Different materials of centrifuge tubes

PP (polypropylene): Translucent, good chemical and temperature stability, but will become brittle at low temperature, so do not be below 4 ℃ during centrifugation.

PC (polycarbonate): good transparency, high hardness, can be sterilized at high temperature, but not resistant to strong acid and alkali and some organic solvents such as alcohol. Mainly used for ultracentrifugation above 50,000 rpm.

PE (Polyethylene): Opaque. It does not react with acetone, acetic acid, hydrochloric acid, etc., and is relatively stable, and it is easy to become soft at high temperature.

PA (polyamide): This material is a polymer of PP and PE material, translucent, very stable in chemical properties, and not resistant to high temperature.

PS (polystyrene): transparent, high hardness, stable to most aqueous solutions, but will be corroded by various organic substances, mostly used for low-speed centrifugation, and generally one-time use.

PF (polyfluorine): translucent, can be used at low temperature, if it is an experimental environment at -100℃-140℃, centrifuge tubes of this material can be used.

CAB (Cellulose Acetate Butyl): Transparent, can be used for the gradient determination of dilute acids, alkalis, salts, as well as alcohol and sucrose.
