Description
Pressure equalisation set GL 14 is a laboratory accessory for controlled pressure balancing on vessels and bottles fitted with a GL 14 thread. It incorporates a membrane with a diameter of 12 mm and is supplied as 1 pc, with a net weight of 0,006 kg. The set belongs to seals, hose connectors and related container accessories used with laboratory glass, vessels, bottles and canisters. By equalising internal and external pressure through the membrane interface, it supports safe handling and storage of liquids in closed systems where pressure differences can otherwise form. The GL 14 connection matches common laboratory bottle and vessel closures of that thread size. This pressure equalisation set from manufacturer Bohlender is suited to routine labware configurations that require a compact membrane-based venting solution. It is positioned for use alongside containers, bottles and sealing accessories in analytical and preparative laboratory environments where reliable pressure equalisation at GL 14 ports is required without complex additional hardware.
This article is part of Dropping funnels, in Funnels.

Questions about Pressure equalisation set GL 14, Membrane-Ø 12 mm, 1 unit(s)
What is this article?
Pressure equalisation set GL 14, Membrane-Ø 12 mm, 1 unit(s) is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Dropping funnels, inside Funnels, in Labware.
A dropping funnel adds a liquid slowly into a closed reaction through a stopcock and usually a ground joint. A pressure-equalising arm keeps the funnel from air-locking. The joint size and the volume are the specification.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
