2 Position cap for 12mm diameter tubes
Description
Our two position caps for 12mm diameter tubes are designed so that the cap allows for either a vented closure or a liquid tight closure. If you put the cap on the tube and press the cap all of the way down on the tube, the seal will be liquid tight. If you put the cap on the tube but do not seat it all of the way down, gas can vent in and out of the tube. The cap remains snugly on the tube in either position. The caps are made from polyethylene and are not autoclavable. Packaging is a plastic bag of 1,000 caps.
