Globe Scientific 110409 is a 12 x 75 mm polystyrene test tube, 5 mL capacity.
Globe molds these tubes from polystyrene for clarity and rates its polystyrene tubes to 1,500 RPM in a centrifuge. Its polypropylene tubes are rated to 3,000 RPM and are the ones Globe lists as autoclavable and freezable.
Globe pairs its culture tubes with LDPE dual-position snap caps: left in the loose position for aerobic work, or pressed to the sealed position for anaerobic cultures.
