Common centrifuge tube materials

Glass centrifuge tubes cannot be used in high-speed or ultra-speed centrifuges.
PP (polypropyiene, polypropylene) is translucent. Stable chemical and temperature performance, but brittle under low temperature. Do not centrifuge below 4°C.
PA (polyallomer, a polymer of polypropylene and polyethylene) is translucent. The chemical property is the most stable, but it tends to become soft at high temperature.
CAB (cellulose acetobutyrate)  LH is used at 0-15℃, HT is used at 20-40℃. transparent. It can be used for dilute acids, bases and salts. But when the pH is above 8, organic solvents, heavy salts such as CsCl can only be used under limited conditions. Suitable for alcohol and sucrose gradients.
PC (polycarbonate, polycarbonate): good transparency, high hardness, and can withstand high temperature disinfection. But it is not resistant to strong acids and alkalis and certain organic solvents such as alcohol, oil, and MDSO. It’s not full. Mainly used for centrifugation above 50,000 rpm.
PCR (polyclear, super transparent)   similar to PC, but harder than PC
PE (polyethylene) is opaque. Stable to acetone, acetic acid, hydrochloric acid, etc. It becomes soft at high temperature and must be filled.
PS (polystyrol, polystyrene) “transparent and hard. It is stable to most aqueous solutions, but can not be stained with many organic substances, and is used for one-time use. Mostly used for low-speed centrifugation.
PF (polyflor, polyfluoride)   -100 ℃-140 ℃ use, translucent.
Stainless steel is resistant to heat, chemical corrosion, and can be autoclaved, but it is heavier and more expensive.
CN tube: The texture is soft and transparent, but it is not resistant to strong acids and alkalis and certain organic solvents, and cannot be autoclaved. It is suitable for sucrose and glycerol density gradient centrifugation. Transparent and easy to collect.
