Mar 18, 2018

Used to deal with the tube wall of the silicone oil has a lot of kinds, there are soluble in water and insoluble in water, soluble in organic solvents and insoluble in organic solvents, viscosity is extremely easy flow of liquid and semisolid fluid. In the meantime, it is not easy to choose the silicone oil which is suitable for the treatment of blood vessel wall and has good chemical and physiological inertia. The inner wall should be very smooth. Through the simple water experiment, we can distinguish the good and bad treatment of the tube wall. The two milliliters of water will be put in a test tube and then poured out, and the inside wall of the tube that is silicified is the one that is not scattered. It is conceivable that the vacuum tube without the wall phenomenon of blood cells has laid a good foundation for the separation of high quality serum.
