MTC Bio&#153; new DuoClick&#153; 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 (see flow-chart below). 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. Features:<ul Style="Margin-Top:0Px; Padding-Top: 5Px; Padding-Bottom: 5Px;"><li>New patent pending screw-cap</li><li>Aerobic culturing at first click</li><li>Anaerobic after second click</li><li>Printed graduations</li><li>Flat, markable screw-cap</li></ul>
