Centrifuge Tubes, 50 ml, Simport Scientific
These centrifuge tubes are useful for collecting and transporting biological specimens.
- Polypropylene or polystyrene tube options
- Sterile or non sterile versions available
- Cap features a leakproof design
- Polypropylene tubes are autoclavable
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 and they will also resist acids, solvents, and alkalis at room temperature. They withstand centrifugation speeds of 3000×g.
Polystyrene tubes can tolerate aqueous solutions of mild bases or weak acids, but not organic solvents, aromatic or chlorinated hydrocarbons. Polystyrene tubes cannot be autoclaved. They withstand centrifugation speeds up to 1000×g.
Tubes are available in bags or in polypropylene racks for better protection during transport or storage, and for convenient laboratory use. Racks can hold up to 25 tubes. Tubes are supplied sterile with green caps or nonsterile with yellow caps.
