As a veteran manufacturer of blood collection tube additives, Desheng has a small workshop to today's large factory. In the ups and downs of the world, it can always maintain its progress, which can only mean that it has been keeping up with the pace of this era, working hard to make every product of it, so that all those who have been exposed to their products Both individuals and companies applauded. I think the success of an enterprise is ultimately inseparable from product quality and service. Since it is an old blood collection tube additive manufacturer, what are their blood collection tube additive products? Serum separation gel, heparin sodium, lithium heparin, dipotassium EDTA, tripotassium EDTA, coagulant, siliconizer, sodium citrate, potassium oxalate, etc. Each product has its characteristics and uses, but who is the one among these products? From the point of view of use, sales and production, the serum separation gel deserves to sit on the throne. Serum separation gel is a substance that separates serum (plasma) and blood cells (blood cells). Separating gel can not only be used with coagulant but also with anticoagulant such as heparin salt, EDTA salt and sodium citrate. The separation glue is used for the preparation of high-quality specimens and for specimen storage and transportation. If separation gel is not used in the blood collection tube of the coagulant, although it can also accelerate blood coagulation and form a blood clot and separate the serum, but the blood clot is in contact with the serum for a long time, there will be material exchange, and the blood cells are very fragile and hemolysis is easy to interfere with the serum sample , The use of separating glue to separate the barrier can solve the problem. Generally, 0.8-1.2g of separating glue is added to each blood collection tube to form an isolation layer of at least 5mm between different components of the blood to ensure the high quality of blood samples. The pure EDTA additive is a routine blood tube, while the use of EDTA dipotassium and serum separation gel together is suitable for the collection, transportation and storage of venous blood samples for nucleic acid testing. It is for DNA amplification testing of HBV DNA, HCV, and HIV. Serum separation gel can effectively block the interference of hemoglobin in red blood cells on nucleic acid detection experiments. We invest a lot of manpower and material resources in serum separation gel every year. Last year we also obtained a patent due to the technical improvement of separation gel, which increased our output from 500 tons per year in the previous period to 800 tons. Sales are also large. The rate of increase is even more exported to home and abroad. No matter from which aspect, the serum separation gel is one of the blood collection tube additives. And our other products are only relative to the separation glue, which may not be so brilliant, but the market share is also commendable.
