For serum, biochemistry, immunology, drug testing, etc., on the inner wall of the uniform coating coagulant, 

can greatly shorten the blood coagulation time, due to the introduction of Japanese imports of separation 

gel was pure substance, its physical and chemical properties is stable, strong heat resistance, effectively 

avoid in the process of storage and transportation, separation gel decomposition degeneration, centrifugal 

separation adhesive to form a barrier to to fully separate the serum and blood cells, effectively prevent 

between material exchange, to obtain the high quality of the serum, make the test results more real, 

increase the rate of serum collected and maintained serum stability over a period of 48 hours, does not 

have a significant change in the composition of its biochemical properties and chemical can be directly 

on the machine. Blood clots completely contraction for 20-25 minutes, speed centrifugal to 3500-4000 

rpm, centrifugal time of 5 minutes, it is recommended storage temperature 25 degrees
