1, Plastic Centrifuge Tube Advantages of plastic centrifuge tube transparent or translucent, its small hardness, can puncture remove gradient. The disadvantage is easily deformed, poor corrosion resistance to organic solvents, life is short. To prevent sample leaking plastic centrifuge tube has a lid, its role is to prevent sample leakage, particularly for radioactive or corrosive samples have time is a very important point; there is a lid is to prevent sample volatilization and support tube to prevent tube deformation. Note also that in the selection of this time to check whether the tight lid, in the test can Gaiyan to reach the inversion does not leak; We all know that in the plastic centrifuge tube, commonly used materials are polyethylene (PE), polycarbonate (PC), polypropylene (PP), of which polypropylene PP tube performance is relatively good, so we in the selection of plastic centrifuge possible consideration of polypropylene plastic centrifuge tube when the tube. 2, Glass Centrifuge Tube When using glass centrifugal force should not be too big, we need to pad rubber mat to prevent broken pipes, generally do not use the high-speed centrifuge tube. Tube cap closure is not good enough, the liquid can not fill (for high-speed centrifuge and using angle rotor) to prevent spills, loss of balance. Spillover effects of pollution rotor and centrifugal chamber, the impact of the sensor to work properly. When ultracentrifugation, liquid filled tubes must be, because the ultra-high vacuum pump from need only to fill in order to avoid tube deformation. 3, Steel Centrifuge Tube The steel tube strength, no deformation, can heat, frost, resistance to chemical corrosion, its application is quite extensive, but when using the same should also avoid contact with corrosive chemicals, such as acids, alkalis and so on. Try to avoid corrosion of these chemicals.
