Borosilicate Glass Centrifuge Tubes

Choosing glass centrifuge tubes, but because of the material characteristics of glass itself, the application of glass centrifuge tube at high speed is restricted. Generally, the highest endurance speed of glass centrifuge tubes is about 4000 rpm.Plastic centrifuge tubes can withstand the need for higher rotational speed, while centrifugation its safety performance is far better than glass centrifuge tubes. But in some specific experiments, such as the need to load some organic solvents, ordinary plastic centrifuge tubes are often not competent. This is mainly manifested in the material problems, may have impurities from the centrifuge tube seepage into organic solution, or because of the centrifuge tube cover sealing problems, leading to leakage of organic volume.
