Carbomer is a kind of nano grade acrylic acid resin. When water is rising and a small amount of mixture is added (such as triethanolamine and sodium hydroxide), a high transparent gel is formed. Different types of carbomer represent different viscosity, such as short rheological or long rheological, such as: carbomer 940 has short rheological property, and its viscosity reaches 63000MPA.S at 0.5%. It is suitable for high viscosity products. Carbopol 941 has long rheological properties, and its viscosity reaches 7500mpa. S at 0.5%. It is suitable for low viscosity products. Carbopol 941 has ion or salt resistance, and is suitable for daily chemical and industrial products.   The thickening mechanism of carbomer is as follows   Neutralization thickening: carbomer is usually neutralized to form salt, which makes the curly molecules thicken due to the opening of electric repulsion force. Sodium hydroxide and triethanolamine are commonly used neutralizing agents, which is also the reason why carbomer is sensitive to ions. Hydrogen bond thickening: as carboxyl donor, Carbomer molecules can combine with one or more hydroxyl groups to form hydrogen bond and thickening. This neutralization method takes time, and the commonly used hydroxyl donors are non-ionic surfactants, polyols, etc.   There are two dissolution methods of carbomer A: The common method is to dissolve every other day. If you want to use it on the next day, soak it on the previous day. First, add carbomer into deionized water according to the actual production requirements to dissolve it without stirring. After carbomer absorbs water naturally, the neutralizer (triethanolamine or sodium hydroxide solution) is added, adjust the pH value to about 7, and use a round tool or disperser And stir evenly at low speed.   B: was dissolved by high-speed dispersant and added to the actual production ratio. The disperser did not have white powder and added neutralizer to form the gel. Then the vacuum emulsification pot was used to remove the air from the gel, and then worry too much.     It should be noted that when using common methods, Carbomer can not be stirred in water. For example, when adding carbomer while stirring, Carbomer will form a white water ball. The surface has absorbed water, but there is no water in it. After neutralization, many water white spots can be seen, and a large number of bubbles can be formed. Carbomer has high viscosity, and bubbles are difficult to eliminate by themselves. Even if a certain amount of defoamer is added, it is difficult to eliminate the bubbles. In this case, the vacuum pot can only be used to eliminate the bubbles, which increases the difficulty of operation to a certain extent.   Warm tips of carbomer dissolution The dispersion time of various types of carbomer in water is related to the water temperature and quality. It is recommended to use deionized water to make the product more stable. If it is dissolved directly in organic solute, it will take longer. For example, for solid alcohol, Carbomer 940, 941, 934, 980 and 981 need soaking for about 8 hours, Carbomer 2020 U10 U20 needs to be soaked for about 4 hours. The specific dissolution time is related to the dissolution amount. If you have more questions, please contact the customer service on Desheng's official website at: www.whdsbio.com

Novel coronavirus pneumonia has been nip in the bud. Recently, the European and South American multi national epidemic situation is again in urgent demand. The three regions of France and Spain, the two Greek area are again blocked, and the emergency situation in many countries is once again extended. Although our country is relatively safe at present, it is also necessary to intensify the prevention and control of the epidemic side to prevent the disease. In response, it is not too much to say that it is a worthy meritorious official to launch an efficient and stable Virus Transport Media to assist nucleic acid detection.   First of all, let's understand the characteristics of the virus. The virus is composed of a nucleic acid molecule and protein or only protein. The individual is small and the structure is simple. The common epidemic infectious diseases are usually RNA viruses, such as influenza virus, HIV and influenza A virus.   Because there is no cell structure, the virus itself can not replicate. Instead, it invades the host cells with genes and uses the latter's replication system to replicate new viruses. What we call COVID-19 is also RNA virus. New Coronavirus is not an independent life body. It needs invasion to live cells. It can reproduce and release more progeny virus particles by using the energy and material and molecular encoding function of living cells.     High concentration guanidine salt can quickly inactivate and preserve respiratory pathogens in inactivated Virus Transport Media, which makes the samples lose infectivity. The inactivated samples can be used with a variety of virus DNA / RNA extraction kits, M32 / M96 nucleic acid extraction instrument for rapid nucleic acid extraction, and PCR detection kit for respiratory pathogens for rapid detection. The specificity and sensitivity are not affected.   In addition to inactivated virus, there are also non inactivated virus. The non inactivated virus contains Hanks solution, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids. The combination of multiple antibiotics has anti-tumor effect   The function of bacteria and antifungal; bovine serum albumin (BSA) as a protein stabilizer can form a protective film on the protein coat of the virus, making it not easy to decompose and ensuring the integrity of the virus; the neutral environment constructed by Hanks buffer can help to increase the survival time and infection stability of the virus.   Desheng's non inactivated Virus Transport Media has the advantages of good sampling effect and more accurate detection. It can provide free samples of {Virus Transport Media} according to customers' needs. Desheng's Virus Transport Media has both inactivated and non inactivated types, which can meet the different needs of different organizations for Virus Transport Media. Each bottle is packed with 1L and 5L separately, which is convenient to use, with good sampling effect and reliable quality, For you to bring a different use experience. For example, the conventional packaging is 1L / bottle and 5L / barrel. Of course, if you need other specifications, it also supports customization.

HEPES buffer is 2 - (4 - (2-hydroxyethyl) piperazine) ethanesulfonic acid, CAS 7365-45-9. This buffer is usually used in biochemical experiments to adjust the pH value of the reaction system, such as virus preservation solution or cell preservation solution.   There are two types of HEPES buffer on the market: powder reagent and solution reagent. The concentration of HEPES solution is 10-50 mmol / L, and the buffer capacity can be achieved when the culture medium contains 20 mmol / L HEPES. Moreover, this kind of buffer has many advantages over phosphate buffer. It is non-toxic to cells and can control the constant pH range for a long time. It is a good hydrogen ion buffer.   hepes powder   The dissociation constant of HEPES buffer is 7.65 (at 20 ℃), and the pH buffer range is 6.6-8.6, which is generally suitable for the reaction system with pH 6.8-8.2. It can be used directly with sodium hydroxide, or mixed with salt and adjusted pH with sodium hydroxide.   1、 500 ml of 1 mol / L HEPES, pH 7.0, stock solution: weigh 0.5 mol (119.15 g) of hydroxyethyl piperazine ethanesulfonic acid, then adjust to the required pH value with 0.5 m ~ 1 M sodium hydroxide, finally fix the volume with distilled water, and seal at 4 ℃.   2、 HEPES buffer 500ml with a small amount of salt: HEPES ＞ 6.5g, NaCl ＞ 8.0g, na2hpo4.7h2o ＞ 0.198g, adjust pH value with 0.5m NaOH ＞ water solution, finally fix volume and store at low temperature.   3、 Preparation of 2 × HEPES buffer salt solution: 1.6g NaCl, 0.074g KCl, 0.027g na2hpo4.2h2o, 0.2g glucan or dextran and 1g HEPES were dissolved in 90ml distilled water, adjusted to the required pH value with 0.5m NaOH, and then diluted to 100ml with distilled water.   Although the buffer system of HEPES is not as extensive as that of PBS, it has more advantages. The ionic strength of PBS is higher than that of HEPES, and the ionic strength will affect the solubility of other solutes in the mixed solution. In general, where PBS can be used, HEPES can be used, but where HEPES is used, PBS cannot be replaced.   HEPES buffer is similar to pipe, but the water solubility of pipe is poor, so it can be made into sodium salt of pipe. The two buffers provided by Desheng are powder reagents, which can also be prepared into ready-to-use buffer solutions with specific concentrations if required.

Bicine, N, n-di (hydroxyethyl) glycine, CAS 150-25-4, is a white crystalline powder. Soluble in water, insoluble in acet one, DMAC, DMSO, DMF and other organic solvents.   Bicine buffer is a pH buffer suitable for biochemical and medical research. In the range of pH 7.6 ~ 9.0, the pKa value is 8.3 at 25 ℃. This property makes bicine often used as a buffer solution for capillary electrophoresis. It is also the recommended buffer for low temperature biochemical work. Its molecular structure is similar to glycine. Buffer is recommended in low temperature biochemical work of biological buffer. It was used to prepare stable substrate solution for the determination of serum guaninase. It is also a widely used buffer for enzyme reaction buffer and electrophoresis buffer. The working concentration is 3-100ml   Product packaging   [recommended usage]   1. Preparation of storage solution for cell culture related experiments: dissolve according to the solubility in the table.

There are many kinds of additives for blood collection, such as anticoagulants, accelerators, separation gels, etc. In order to distinguish the use of different blood collecting vessels and additives, different cap colors are used internationally to mark blood collecting vessels. The functions of different color caps are different, some added anticoagulants, some added accelerators, and some blood collecting vessels without any additives. What is the role of different additives in blood collection? Desheng, as an old manufacturer of vascular additive, can help you solve your doubts.   Red head: no additives, common serum tube for routine biochemical and immunological tests.   Orange red head cap: coagulant, can activate fibrin, make soluble fibrin into insoluble fibrin polymer, and then form a stable fibrin clot. The rapid serum tube can coagulate the collected blood in 5 minutes, which is suitable for emergency series tests.   Golden head cover: separation gel and accelerator. After centrifugation, the separation gel can completely separate the liquid components (serum or plasma) and solid components (red blood cells, white blood cells, platelets, fibrin, etc.) in the blood, and completely accumulate in the center of the test tube to form a barrier. The sample remains stable within 48 hours. Coagulant can quickly activate the coagulation mechanism and accelerate the coagulation process, which is suitable for emergency series tests.   Green head cover: heparin, suitable for hemorheology, erythrocyte fragility test, blood gas analysis, hematocrit test, general biochemical determination. Heparin has the function of antithrombin and can prolong the clotting time of samples, so it is not suitable for hemagglutination test. Excessive heparin can cause leukocyte aggregation and cannot be used for leukocyte count. Because it can make the background of blood stained light blue, it is not suitable for morphological examination. Light green head cover: separation gel and heparin lithium can achieve the purpose of rapid separation of plasma. It is the best choice for electrolyte detection. It can also be used for routine plasma biochemical detection and emergency plasma biochemical detection in ICU.   Purple head cover: EDTA anticoagulant, the anticoagulant is ethylenediamine tetraacetic acid (EDTA), which can combine with calcium ion in blood to form chelate, and make Ca2 + lose coagulation, so as to prevent blood coagulation. It is suitable for many kinds of hematological examination. However, EDTA can affect platelet aggregation and is not suitable for coagulation test, platelet function test, calcium ion, potassium ion, sodium ion, iron ion, alkaline phosphatase, creatine kinase and PCR test.   Light blue head: sodium citrate anticoagulant, sodium citrate mainly through chelating with calcium ions in blood samples and anticoagulant effect, suitable for coagulation test.   Black head cover: sodium citrate ESR test tube, the concentration of sodium citrate required for ESR test is 3.2% (equivalent to 0.109 mol / L), and the ratio of anticoagulant to blood is 1 ∶ 4.   Gray head cover: potassium oxalate / sodium fluoride. Sodium fluoride is a weak anticoagulant. It is usually used in combination with potassium oxalate or sodium ethyliodate. The ratio is 1 part of sodium fluoride and 3 parts of potassium oxalate. It can not be used in the determination of urea by Urease method, nor in the determination of alkaline phosphatase and amylase. It is recommended to be used in the determination of blood glucose.   What we should pay attention to after blood collection: A. After the injection of blood, pay attention to shake well, the force should be moderate to prevent hemolysis. B. The amount of blood injected should be strictly in accordance with the volume marked on the test tube. C. The blood from different color tubes should not be poured into other color tubes, otherwise it will lead to wrong results. D. The needle should not contact the wall of the test tube to avoid contact with anticoagulant, resulting in wrong results.

As we all know, Carbomer belongs to acrylic resin. As a kind of high-quality thickener raw material for cosmetics, it has the remarkable characteristics of thickening, suspension, emulsification and pseudothixotropy. According to the customer's search needs, Carbomer 940 and carbomer 2020 are the most popular thickeners. Desheng technology, as a professional manufacturer of carbomer series products, has a professional R & D team and mature production technology. The following is a brief summary of the differences in performance characteristics between carbomer 940 and carbomer 2020.   Carbopol raw material   First of all, let's understand some common features of Carbopol resin   1. Swelling: Kaposi resin is hydrophilic in acidic form and easy to swell in water and polar organic solvents.   2. Weak acidity: Kaposi resin is an acrylic polymer containing polyether crosslinking. Because of 56% - 68% carboxylic acid group in the molecule, these resins are weakly acidic. Although they are weaker than acetic acid, they are easy to react with inorganic bases and organic bases to form salts.   3. Functions and uses: Carbopol resin can be used as excellent suspending agent, stabilizer, emulsifier, transparent matrix of high-grade cosmetics and pharmaceutical excipient matrix, and is also the most effective water-soluble thickener.   Performance characteristics of carbomer 2020:   Carbomer 2020 is an easily wettable hydrophobically modified acrylic (ester) cross-linked polymer. As a water-soluble rheological modifier, it not only has the functions of thickening and suspension, but also has a short wetting time in water, which is better than carbomer 940 and more convenient to use. In addition, it has excellent salt resistance and is compatible with surfactants It can be used in the formula containing electrolyte, but carbomer 940 is not ion resistant and cannot exist in the strong electrolyte system. Applications: skin care emulsion, cream, alcohol based transparent gel products, transparent skin care gel, hair styling gel, shampoo, shower gel.   Features of the carbomer 940:   Carbomer 940 is a white loose powder with strong hygroscopicity. The pH of 1% aqueous dispersion is 2.5-3.0. Gel can be neutralized by alkaline substances.   After carboxy group is ionized by carbomer neutralization, the molecular chain is dispersed and extended due to mutual repulsion of negative charges, showing a state of great expansion and viscosity. The effective thickening range of the hydrogel system is within PH5-10. Application: Carbopol 940 can be used as excellent suspending agent, stabilizer and emulsifier. Carbopol resin can be used as transparent matrix of high-grade cosmetics and pharmaceutical excipient matrix. Carbopol resin is also the most effective water-soluble thickener.   In cosmetic gel, water must be soaked or taken for a long time, because carbomer 940 has a swelling process with water, and the time is too short to dissolve the ball. Secondly, we need to see if other components in the system contain electrolytes. Many natural plant components basically have electrolytes, such as flower water, extract, plant extract and so on. When there is electrolyte, it is necessary to select ion resistant thickener carbomer 2020; if there is no electrolyte problem in the system, Carbomer 940 can be selected.   Carbomer gel   Therefore, in the cosmetic configuration, Carbomer 940 and carbomer 2020 are widely used as thickening agents. General cream (no strong electrolyte) is mainly used in carbomer 940, while carbomer 2020 is mainly used in skin care emulsion, cream, alcoholic transparent gel products, transparent skin care gel, hair styling gel, shampoo and Shower Gel.   Desheng technology is a professional manufacturer of carbomer, with advanced production equipment and mature production technology, with an average daily output of tons. The carbomer powder produced by the company is whiter and more fluffy than that on the market, with better transparency after dissolution. According to the customer response, the effect of product use is good, can support free application sample trial, welcome to inquire and order!

  Tris(hydroxymethyl)aminomethane is also abbreviated as tris base, CAS77-86-1, alias tromethamine, ammonium tromethamine, trimethylaminomethane, is a commonly used biological buffer, conventionally produced as white crystalline powder, PH value Weak base, the buffer range is between 7.0-9.2.   Application of Tris in activated carbon   Modern people pay more and more attention to the quality of life, but many living environments and office environments have more or less harmful gases such as formaldehyde and benzene. The use of activated carbon has become the choice of many people, using activated carbon to adsorb these harmful gases. Among them, tris is used as modifier, and then through hydrothermal reaction, the denatured activated carbon is better used in life.   Preparation method of Tris in activated carbon   What is introduced here is the method of adsorbing trace sulfur dioxide by modified activated carbon fiber, which belongs to gas adsorption and separation technology. Using tris, serine, alanine, etc. as the basis to make modifiers to treat viscose activated carbon fibers, through hydrothermal reaction under fixed conditions, to prepare chemically modified activated carbon fibers with a large number of amino groups on the surface.   Preparation by this method has the following advantages: (1) Small molecules are used to ensure the modification of the modifier surface, and the high ratio of activated carbon fiber is maintained, so that the porous structure in the activated carbon will not be destroyed, thereby better adsorption The harmful substances in the air increase the amount of adsorption; (2) This method is relatively mild, has less pollution, is easy to scale up production and guarantees the environment to a certain extent; (3) Use tris (hydroxymethyl) aminomethane and other chemical reagents to modify After modified activated carbon, its adsorption capacity can be increased to 40-60mgSO2/g adsorbent, which is 4-6 times higher than before modification.   Desheng tris meets the requirements for activated carbon modification   In fact, the number of tris manufacturers on the market is decreasing, not only because of the relatively serious safety accidents in 2019, but also because of the emphasis on the environment, many manufacturers actually cannot meet certain requirements. Desheng Biochemical has been testing tris since 2012. It has a professional R&D team, and has accumulated experience in continuous experiments. According to market requirements, it has invested in pilot and large-scale trials, and it has the current large-scale production. The amino methane products are adapted to various needs, and there is no problem with modified activated carbon. Special indicators can also be customized! The quality of a manufacturer can be seen from the receipt of the goods, Desheng welcomes your consultation!      

Carbomer is a high molecular polymer crosslinked by acrylic acid and allyl sucrose or allyl pentaerythritol. It was first produced by g00drich company of the United States, and its trade name is carbomer. Chinese Pharmacopoeia 2005 edition has been included. This product is a loose white powder, with acidity, hygroscopicity and special odor. It is soluble in water, ethanol and glycerin.   The advantages of carbomer are good gel, sticky, thickening, emulsifying, suspending and film-forming properties. The chemical properties are stable, safe, non irritating and hypersensitive. They are very compressible under low pressure and are compatible with most other excipients.   It can increase the bioavailability and show a good correlation in vitro and in vivo. The drug preparation with zero order release rate can be made. It can form soluble gel type internal salt with basic drugs, so that the drug can release slowly. Salt electrolytes can reduce the viscosity of carbomer gel. Alkaline earth metal ions and polymers can be combined to form insoluble salts. Strong acids can also cause carbomer to lose viscosity, and must be avoided in compatibility.   Disadvantages: 1, hygroscopicity, easy to caking, storage should pay attention to moisture. 2. Carbomer dry powder and high concentration mucilage are irritating to eyes, nose and throat. After contact, it can be rinsed with physiological sodium chloride solution. 3. Non solid state has no antibacterial effect, but does not support the growth of bacteria, so preservatives should be added.   carbomer gel   Because of its advantages, Carbomer is widely used, but it also has disadvantages, among which group formation is the problem that most customers respond to. Many manufacturers will encounter various problems when using Carbomer, because carbomer has strong hydrophilicity. Carbomer of dry powder has strong hygroscopicity. Like other hygroscopic powders, it is easy to form clusters or incomplete wetting when it is put into water or other polar solvents by improper methods.   Other powders will eventually decrease and dissolve after agglomerating, but carbomer will not dissolve easily after agglomerating, because once the outer layer of the agglomerate is completely infiltrated, water is not easy to penetrate into the internal dry part, and finally agglomerate.   Desheng, as a professional manufacturer of cabom, according to the experience of engineers in the technical department, sorts out several methods here for reference. 1. Sprinkle carbomer on the water (Note: carbomer sprinkles on the water, not carbomer adds water), and keep it still for one night to make it fully dissolve and swell; 2. Grind carbomer and glycerin (or propylene glycol, according to the prescription) in mortar, and then add water to grind evenly; 3. Add a certain amount of water into the mixer, slowly add carbomer under rapid stirring, and continue stirring for 1-2 hours after adding to make it fully dissolve;   Desheng friendly reminder:   1. If it is a laboratory test, it is recommended to use 2 and 3 methods;   2. If it is a pilot plant or production, it is more appropriate to use methods 1 and 3. If method 1 is used, there may be jelly like lumps, but it is not a big problem: after a colloid mill, a very uniform colloid can be obtained. After the colloid mill, there may be more bubbles, which can be eliminated by vacuumizing and placing overnight;   3, the above method is only to get carbomer colloid. To get gel matrix, we must adjust PH to 6-10 by triethanolamine or sodium hydroxide solution. The resin particles must be evenly dispersed in cold water. Under the high speed of 500-800rpm, the carbomer can be sieved into the stirring vortex by screen. The optional dispersion equipment can be ejector, flocculation disperser and conventional disperser.   The methods explained above are purely personal experience. The Carbomer manufacturing equipment used by each company is different, and the methods vary from person to person. If you know other good ways to avoid kapom forming a group, you are also welcome to leave a message for Desheng to learn together. Kapom has many different models. Desheng's current sales volume and feedback are Carbomer 980 and Carbomer 940, which are available from stock. Welcome to contact us Inquiry and order!

Situation Analysis of Tris   In the past few years, the development speed of tris base (tris(hydroxymethylaminomethane)) CAS77-86-1 is very fast and has achieved visible growth. This is not only the case in China, but also in North America, Europe, the Middle East, Africa and other regions. Large companies in many countries directly use mergers and acquisitions to promote the growth of the entire market.   The relatively large manufacturers of tris hydroxymethylaminomethane have certain plans for market liquidity and future development. Along with different influencing factors, all will be directly related to the market of tris. More new tris production capacity will also get new opportunities.   Factors affecting tris   TRIS (Tris(hydroxymethylaminomethane)) (CAS 77-86-1) market growth drivers, constraints, future opportunities and challenges. The use of tris in biological buffers is more and more widely used, and there are no alternative biological buffers, making the use of tris indispensable.   The limiting factor lies in the timely supply of raw materials. Compared with domestic considerations of environment and safety, more foreign sources are the timely supply of various raw materials. The future development of tris will be more rapid, but it will benefit from good manufacturers and good product quality.   The Challenge of Tris   Facing the demand for a large amount of tris, the manufacturers of tris is more need to consider how to produce the product more efficiently and ensure product quality. Large-scale production of TRIS (Tris(hydroxymethyl)aminomethane) (CAS 77-86-1) will be a better way to reduce costs, and improving the production process is also an issue. Although the competition is fierce, benign stimulation is necessary.   The impact of the new crown epidemic on the TRIS (Tris(hydroxymethyl)aminomethane) (CAS 77-86-1) market The impact of the COVID-19 epidemic on the tris is undoubtedly huge. It brought the global economy into a deadlock suddenly and caused a catastrophic disaster. However, there are also new opportunities in the tris. The newly developed virus preservation solution often requires the tris for debugging. Compared with other products, tris has shown some growth.   Global TRIS (Tris(hydroxymethyl)aminomethane) (CAS 77-86-1) market   North America (U.S., Canada, Mexico) Europe (Germany, United Kingdom, France, Italy, Russia, Spain and the rest of Europe) Asia Pacific (China, Japan, India, Russia and other Asia Pacific regions) Latin America (Cuba, Brazil, Argentina and The rest of Latin America) the Middle East and Africa (South Africa, the Gulf Cooperation Council, and the rest of the Middle East and Africa).   As a professional manufacturer of tris (tris (tris(hydroxymethylaminomethane)) CAS77-86-1, Desheng Biochemical not only maintains the quality of the products, but also pays attention to the timely supply of products. Friends in need can contact Desheng!

The 2019 new crown pneumonia (COVID-19) is affecting the entire global market. In addition to the cost of human life, the impact of the spread of the virus on the global economy has begun to be recognized and has a profound impact on the world's technology supply chain. Measures such as large-scale quarantine, travel restrictions, and social isolation have led to a sharp drop in personal and corporate spending. Companies lose income, lay off employees, and unemployment has risen sharply. Carbomer was once the darling of daily chemical products due to its application as a hand sanitizing gel. It is precisely because of the surge in market demand that carbomer was out of stock for a time.   Facing this severe situation, Desheng looked for opportunities in adversity, established a technology research and development center, increased investment in research and development, and received a good market feedback. There are currently hundreds of cooperative enterprises, so why Carbomer With so many manufacturers, does the customer prefer AdSung? Here are the following points.     1. Is a real manufacturer, not a trader It is also necessary to understand the supply background. Although there are some domestic manufacturers that produce carbomers, some of them are not of good quality, and some are not specialized in producing this product. Perhaps because they think it is the general trend, they did not spend too much. Human, material and financial resources to develop and produce, if the inventory is not enough, this will also bring a lot of inconvenience to subsequent cooperation, and the real manufacturer will not worry about this problem, for example, Desheng has its own professional R&D team. There is no need to worry about the quality of the product at all, and if there is a problem, you can return it without worry.   2. Product trial available If the product is good or not, you can tell when you try a sample. Nowadays, when looking for a product, some purchasers usually communicate in words first, and then communicate by phone when they think it’s suitable. This is actually low efficiency. More importantly, some customers don’t pay attention to the performance parameters of the product at all. Ask the price, if the price is right, if you don’t want to buy it, then you don’t need to talk about it. At this time, it is a very good experience to provide samples for trial. Customers will no longer struggle with the price. If the trial is good, they will naturally "visit" again, and they will naturally choose another home if they are not used well. . Desheng has done statistics, as long as the customers who have tried the product have 100% repurchased,   3. High daily output and fast delivery Many customers’ order quantity is very large.
