Chemglass Life Sciences GL-14 Demers TFE Delivery Tip, Package Of 10
GL-14 Demers TFE Delivery Tip, Package Of 10. Removable TFE delivery stem virtually eliminates the breakage normally associated with standard glass stem stopcocks. Made entirely of TFE, the stem attaches directly to the glass thread without o-rings or other gaskets. Glassware equipped with this stem can survive repeated forceful strikes to the stem without breakage. They have also been dropped from a height of 3 ft without breakage, so long as the initial impact was received by the TFE stem. US Patient Number: 5,580,528.
