How to choose a centrifuge tube for a centrifuge

November 07, 2022

The centrifuge tube is mainly made of plastic and stainless steel. The commonly used materials for plastic centrifuge tubes are polypropylene (PP), polyethylene (PE), polycarbonate (PC) and the like. Among them, the performance of PP tube is good. The advantage of plastic centrifuge tube is transparent (or translucent), the hardness is small, the gradient can be taken by puncture method, the defect is easy to deform, the corrosion resistance to organic solvent is poor, the service life is short; the strength of stainless steel centrifuge tube is large. It is non-deformable, can resist frost, heat and chemical corrosion, but it should be used to prevent contact with highly corrosive chemicals such as strong acids and alkalis.

Here we mainly introduce plastic centrifuge tubes: plastic centrifuge tubes have tube caps, and the tube caps must be tightly sealed before centrifugation. The tube cover has three functions: 1 to avoid sample leakage, when used for samples with radioactivity or strong corrosivity; 2 to avoid sample evaporation; 3 to support the centrifuge tube to avoid deformation of the centrifuge tube. The data, chemical stability and physical properties of plastic centrifuge tubes are as follows:
Plastic centrifuge tube data

Information (Chinese and English) title	Abbreviation	Performance
Polyethylene	PE	Good chemical resistance
Polypropylene	PP	Medium strength, high temperature and high pressure sterilization, brittle translucent below 4°C
Polycarbonate	PC	High transparent strength, high temperature sterilization
Stainless steel (Stainless)	SS	High strength, high temperature and high pressure sterilization
Cellulose	CAB	Transparent
