Description
Filling/vent cap in polypropylene (PP), 83 mm, is a practical closure for laboratory carboys, canisters and similar bulk vessels where controlled filling and venting are required. The cap provides dedicated hose connections sized for 12,7 mm tubing, supporting secure transfer lines during liquid handling, media preparation or bulk reagent storage workflows. Manufactured from durable PP, it suits routine laboratory use with aqueous solutions and many common process liquids. Supplied as a single unit weighing 0,189 kg, the component integrates readily into existing carboy and canister setups used in research, quality-control and production support laboratories. This filling and venting accessory from manufacturer Nalgene helps maintain orderly fluid paths while reducing the need for improvised adapters. It is intended for laboratory containers in the carboys, canisters and barrels category and complements standard labware systems for safe, organised liquid transfer. Ideal where a robust PP cap with defined hose ports is needed for everyday filling, emptying or pressure-equalising operations on larger vessels.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Filling/vent cap, PP, 83 mm, connections for hoses 12,7 mm, 1 unit(s)
What is this article?
Filling/vent cap, PP, 83 mm, connections for hoses 12,7 mm, 1 unit(s) is the article on this page. Luminix Health distributes Nalgene for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
