Description

Port Cap Waste Manifold with built-in venting, GL38, 10-Port, size Large, includes (4) 1/4" NPT ports and (6) x 1/4-28 UNF ports.

Although practically all the safety port caps provided here could be used for either solvent extraction or waste collection, the difference in function lies in how ventilation is handled. During solvent extraction, air must enter the bottle to displace solvent removed - a problem resolved with a one-way check valve. The removeable valve is constructed of inert PTFE components with stainless spring, compatible with most laboratory solvents, with a low opening pressure below 1psi to avoid pump cavitation.

Tubing is secured to threaded ports in the inert PTFE insert. The insert rotates independently from the Polypropylene cap collar - a feature which prevents twisted tubing when the cap is removed. 

Container Type and Thread Size

The 4-liter amber glass bottle with distinctive finger grip is as common in most labs as Parafilm® and pipettes. Used by many chemical manufacturers as the containment vessel of choice for solvents, these bottles are (thankfully) supplied with a more-or-less standardized finish: the "GL38" glass thread. Although compatible with 38-430 caps used on some plastic bottles - such as Nalgene - it’s important to note that the GL38 caps supplied here are not deep enough to engage and seal on many plastic 38-430 bottles. Watch out for 38mm thread variants: increasingly, chemical suppliers utilize a 38-415 thread on 4L bottles instead of the more common 38-430. Although identical in appearance, these two threads aren’t interchangeable.
