[Hand centrifuge]: uses mechanical principles to increase the centrifugal force of the liquid and accelerate the precipitation rate of solid particles in the liquid [Separation principle]: During the working process, coarse particles and fine particles in the liquid are separated based on the difference in particle size and specific gravity [Capacity]: It can accommodate up to 15ml*4 centrifuge tubes. Its operation does not rely on electricity. It can be used anytime and anywhere. It can be used for centrifugal separation demonstration experiments [High quality]: The test tube holder and test tube cover are made of high-strength PP material, which is corrosion-resistant and safer. The machine can be screwed and fixed on the desktop, making it more convenient to use [Application]: Suitable for qualitative analysis of plasma, serum, and urea in hospital laboratories, biochemical laboratories, etc
