Description
These centrifuge tubes are also useful for collecting and transporting biological specimens. Leakproof characteristics are ensured by a flat top plastic screw cap with an inner sealing lip. Tubes are made of translucent polypropylene or optically clear polystyrene with molded graduations from 2.5 to 50 ml.
Polypropylene tubes can be autoclaved and will resist temperatures up to 121 °C; they will also resist acids, solvents, and alkalies at room temperature. They withstand centrifugation speeds of 3000 x g.
Polystyrene tubes can tolerate aqueous solutions of mild bases or weak acids, but not organic solvents, aromatic or chlorinated hydrocarbons, and they cannot be autoclaved. They withstand centrifugation speeds up to 1000 x g.
Tubes are available in bags or polypropylene racks for better protection during transport, storage, and convenient laboratory use.
