Description
Dropping funnel, cylindrical, with pressure equalisation and PTFE stopcock, 29/32, 100 ml supports controlled addition of reagents in synthetic, preparative, and analytical laboratory work. The cylindrical body gives a clear view of the liquid column, and the PTFE stopcock allows precise adjustment from dropwise to continuous flow. An integrated pressure-equalisation feature helps maintain uninterrupted delivery when the funnel is mounted on closed apparatus. Ground joint NS 29/32 matches larger standard joints on reaction vessels and adapters commonly used in organic chemistry setups. Fabricated from high-quality borosilicate glass LBG 3.3 and fitted with a plastic stopper, this model from manufacturer Labbox combines the durability and chemical resistance of LBG 3.3 glassware with convenient PTFE stopcock operation. The 100 ml capacity is practical for medium-scale dosing and reagent transfer. Net weight is 0,240 kg. Listed under dropping funnels with ground joint and dosing funnels, it is a dependable choice for teaching labs, research groups, and quality-control environments that require transparent, chemically resistant glass dosing equipment.

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.
