MTC Bio T8850 Culture Tube, 14mL, 17 x 100mm, PP, w/ separate 2-positi

The MTC Bio DuoClick culture tubes feature a unique screw closure system. DuoClick tubes eliminate the excess force, splashing, and general frustration of traditional snap-cap culture tubes. The advanced cap design includes two distinct positions for aerobic and anaerobic culturing. Just rotate the cap to the first click to secure the cap in the aerobic position or rotate it past the second click for a leakproof, airtight seal for anaerobic culturing. The tubes are available in two plastic polymers, polystyrene (PS) and polypropylene (PP), and two capacities, 5- and 14-mL. Tubes are available sterile and non-sterile and in a variety of packaging configurations. Sterile tubes feature an attached cap and printed graduations, non-sterile tubes come bulk packed without caps attached and without graduations.
