How to choose centrifuge tubes and centrifuge bottles
Centrifuge tubes 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 them, PP tubes have better performance. The advantages of plastic centrifuge tubes are transparent (or translucent), low hardness, and the gradient can be taken out by the puncture method. The disadvantage is that it is easily deformed, has poor resistance to organic solvents, and has a 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 tubes have caps, and the caps must be tightly closed before centrifugation to prevent liquid leakage. The cap has three functions:
① Prevent leakage of samples. 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 centrifuge tube force should not be too large. Rubber pads are needed to prevent the tube from breaking. High-speed centrifuges generally do not use glass tubes.
