SST tube is the abbreviation for Serum Seperator Tube, which is an inert separation procoagulant tube, distinguished by a yellow cap, containing blood coagulant and serum separation gel. Serum refers to the clear, pale yellow liquid that precipitates from the upper layer of blood after coagulation. Most clinical biochemical experiments choose serum as the test sample to determine physical condition based on its changes. Blood can naturally coagulate and precipitate into clear blood within 1-2 hours after leaving the human body, but if the coagulation time is too long, the precipitated serum sample will also be damaged to a certain extent.
Related parameters of SST tubes:
| Index | Describe |
| Material quality | High quality glass material with good biocompatibility and chemical stability |
| Appearance | The cap is yellow and easy to distinguish |
| Structure | Contains serum separation gel and blood coagulant to accelerate blood coagulation and obtain high-quality serum samples |
| Use to | Used for clinical biochemical, immunological, and serological testing, suitable for various medical laboratory testing projects |
| Advantage | The characteristics of rapid serum separation, high sample stability, and high biosafety can improve the accuracy and reliability of detection results |
The use of SST tubes can effectively separate and precipitate serum. The coagulant inside the tube can quickly coagulate blood in a short period of time, while serum separation gel can form an isolation layer between serum and blood clots, prevent blood component exchange, improve detection efficiency, and provide convenience for medical staff. The serum separation gel dedicated to SST tubes should meet the following conditions:
1. The specific gravity range is 1.045-1.065g/cm3. Due to the specific gravity of serum being about 1.02 and the specific gravity of blood clots being about 1.09, in order to extract high-quality serum samples and form an isolation layer between serum and blood clots, the specific gravity of serum separation gel should be between serum and blood clots. After repeated experiments by professional R&D personnel, it has been found that the use of serum separation gel with a specific gravity of 1.045-1.065g/cm3 is relatively ideal.

2. Good thixotropy. After the blood sample inside the SST tube solidifies, it is usually centrifuged. Thixotropy refers to the decrease in viscosity and enhanced fluidity of the serum separation gel under the action of centrifugal force. Due to different densities, blood clots in the blood sample sink, serum precipitates, and the serum separation gel floats between the two. After the effect of centrifugal force disappears, the viscosity and fluidity of the serum separation gel return to normal, and the serum is fixed at the position separating the serum and blood clots.
3. Stability. Firstly, serum separation gel has good physiological inertness, does not react chemically with blood components, does not affect the original shape of serum samples, and does not affect the examination items; Secondly, serum separation gel has good hydrolysis and radiation resistance, which can ensure that the relevant parameters of blood samples do not change within their shelf life.
Desheng has a research history of 18 years on serum separation gel, with relatively mature production technology and product parameters that meet the requirements. It is also one of the few manufacturers in China that can provide a complete set of blood collection additives.

FAQ
How does serum separator gel work?
During centrifugal separation, the serum separator gel enters between the serum component and the clot component to form a partition wall. The partition wall formed by the serum separator gel makes it possible to collect the serum component required for blood tests stably and easily.
What is the purpose of the gel in the SST tube?
Clot activator and gel for serum separator Serum separator tube (SST) contains a gel at the bottom to separate blood cells from serum on centrifugation.
What kind of gel is in the serum separator tube?
After centrifugation, the inert acrylic gel at the bottom of the tube normally occupies the middle position between the cells (clot) and the serum, as its density is intermediate between theirs. The gel then serves as a barrier to diffusion, preventing contamination of the serum with cellular components.
