DuoClick™ Two Position Screw-Cap Culture Tubes

• New patent pending screw-cap!
• Aerobic culturing at first click
• Anaerobic after second click
• Printed graduations
• Flat, markable screw-cap

DuoClick™ tubes feature a unique, patent pending screw closure system. DuoClick™ tubes completely 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 1/4 turn to the first click to secure the cap in the aerobic position. Or, rotate it another 1/2 turn past the second click for a leakproof, airtight seal for anaerobic culturing.

DuoClick™ tubes are available gamma sterilized, with screw caps attached, and in our exclusive ready-to- use rack packaging. Polypropylene tubes can be centrifuged at up to 4,000 x g.

Popular fraction-collector-plate style racks
