1. Take 1 part of silicide and add 100-200 parts of petroleum ether (60-90 ℃ boiling range) (concentration is 0.5-1.0%), mix well.
2. Spray the mixed solution into the test tube, make the inner wall of the test tube uniformly adhere to a layer of the above solution, or immerse the test tube in the above solution, and then take it out after a short stay.
3. Drain the solution downward from the glass tube mouth, place it at room temperature for 2-4 hours to solidify, and then add other reagents after the tube wall is dry and the petroleum ether volatilizes completely, or dry it at high temperature of 90 ℃.
4. Place the plastic test tube at room temperature for 2-4 hours to cure, and add other reagents after the cure is complete, especially when the reagent is an aqueous solution, it can only be added after it is fully cured and the petroleum ether is completely volatilized.
[special storage conditions and methods] the product is sealed and protected from light and water under normal temperature and pressure. It is suggested to store it at 0-15 ℃, and the prepared silicon liquid should be sealed and waterproof.
1. The high-efficiency silicide is a high polymer organosilicon material, which is hydrolyzed and gelatinous in case of water. During tube silicification and solution preparation, the tube, container and measuring tool must be kept dry and clean.
2. This product is mainly used for silicification treatment of glass or plastic surface. In view of the differences of products, technology and environment of each enterprise, small batch test should be carried out before batch use of this product.
[validity period] five years (subject to the production date).
Wuhan Desheng Biochemical Technology Co., Ltd. is a blood testing reagent company established in 2005. The series of blood sampling additives are the first developed and produced by the company, and also one of the most important series products in the past decade.
Blood collection additives include serum gel, heparin sodium, heparin lithium, EDTA K2, EDTA K3, coagulant, coagulant powder and silicide agent introduced here.
The silicide can clean the blood vessels, prevent the blood rupture in the vessels, and make the additives better adhere to the walls of the vessels. Therefore, before adding additives, the manufacturers of blood vessels will carry out necessary silicification treatment.
Desheng biochemical has two kinds of silicides, oil silicide and water silicide. The price of oil silicide is much higher than that of water silicide, and there is a certain risk because it needs to be mixed with petroleum ether. Of course, the effect will be better than that of water-based silicide, but we recommend using water-based silicide, whether for cost or safety.
