Description
Cylindrical dropping funnel with pressure equalisation and PTFE stopcock, 29/32, 500 ml is a laboratory dosing funnel for controlled liquid addition in synthesis and analytical work. Made from high-quality borosilicate glass LBG 3.3, it offers chemical resistance and thermal stability for routine laboratory use. The cylindrical body has a 500 ml capacity and a ground joint NS 29/32 for secure connection to reaction apparatus. A PTFE stopcock provides smooth, chemically inert flow control, while the integrated pressure-equalisation arm allows safe addition under reduced or elevated pressure without opening the closed system. A plastic stopper completes the assembly. This glassware item from manufacturer Labbox belongs to the GLASSCO line and is supplied as one piece with a net weight of 0,240 kg. It suits organic synthesis, extraction setups and general dosing tasks where precise liquid transfer through standard ground joints is required in research, teaching or quality-control laboratories.
This article is part of Dropping funnels, in Funnels.

Questions about Pressure equalising dropping funnel, cylindrical, with PTFE stopcock, 29/32, 500
What is this article?
Pressure equalising dropping funnel, cylindrical, with PTFE stopcock, 29/32, 500 is the article on this page. Luminix Health distributes Labbox 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.
