DuoClick tubes feature a unique, patent pending screw cap closure system that completely eliminates excess force, splashing and general frustration of traditional snap-cap culture tubes. Advanced cap design includes two distinct positions for aerobic and anaerobic culturing. Easy to use - rotate the cap 1/4 turn to the first click to secure the cap in the aerobic position or rotate cap another 1/2 turn past the second click for a leak-proof, airtight anaerobic seal. Gamma sterilized, polypropylene tubes feature flat, markable screw caps, withstand speeds up to 4,000xg, and are supplied with attached caps.
