How to choose centrifuge tube centrifuge bottle

Centrifuge bottles, centrifuge tubes, and pipette tips are mainly made of glass, plastic and stainless steel. Commonly used materials for plastic centrifuge tubes are polyethylene (PE), polycarbonate (PC), polypropylene (PP), etc., among which PP tubes have better performance . Plastic centrifuge bottles, centrifuge tubes, and pipette tips have the advantages of transparency (or translucent), low hardness, and the gradient can be taken out by puncture. The disadvantages are easy deformation, poor resistance to organic solvents, and short service life. The stainless steel tube has high strength, no deformation, heat resistance, frost resistance, and chemical corrosion resistance. However, avoid contact with highly corrosive chemicals such as strong acids and alkalis.

Plastic centrifuge bottles, centrifuge tubes, and pipette tips all have caps. The caps must be tightly closed before centrifugation to prevent leakage. The cap has three functions: ①Prevent the sample from leaking out. This is especially important when used in radioactive or highly corrosive samples. ② Prevent the sample from volatilizing. ③Support the centrifuge tube to prevent deformation of the centrifuge tube. When using glass tubes, the centrifugal force should not be too large. Rubber pads are needed to prevent the tubes from breaking. High-speed centrifuges generally do not use glass tubes.
