Our classic port caps for GL45 and GL38 glass bottles, as well as for Nalgene 38-430 plastic bottles, have 1/4-28 threaded ports in a PTFE insert, with expanded PTFE gaskets. Each port has a through-hole for 1/8" OD tubing, machined at a 10 degree angle; push tubing through the cap to supply your system. Cap outer is made of PP or HDPE, depending on the cap type. 1/8" OD supply tubing may be press-fit into the underside of each cap if needed. Also available are Carboy manifold caps with larger holes alongside the 1/4-28 holes.
These caps are the safety solution for scientists, chemical hygienists, and researchers worldwide, designed to ensure proper delivery and waste containment of industrial chemicals and solvents. Our closed system capabilities reduce harmful emissions which are potentially hazardous to employees and our environment.
