The tubes are molded from premium grade polystyrene for clarity or polypropylene for impact strength and stability to common acids, alkalies, and solvents. Polystyrene tubes can withstand 1500 RPM during centrifugation. Polypropylene tubes can withstand 3000 RPM and are autoclavable and freezable. Tubes with dual position snap caps (LDPE) provide either aerobic or anaerobic storage of samples
The dual position cap is produced from low density polyethylene (LDPE) and is ribbed for easy handling. The cap is specially designed to provide aerobic or anaerobic storage of culture samples. When snapped into the tube, the cap provides a leak-resistant seal.
Note: Leave the cap in the loose position for aerobic work and in the sealed position for anaerobic cultures.
Materials: Tube: Choose from polystyrene (PS) or polypropylene (PP) Cap: Low density polyethylene (LDPE)
