Beschrijving
BOLA dropping funnel, 250 ml, NS 29/32 FEP is a transparent laboratory dosing funnel for controlled reagent addition under chemically demanding conditions. The funnel body is manufactured from transparent FEP, while the fine-dosing stopcock carries a ground joint core NS 29/32 made of PTFE. An integrated Combi nut in SAFE LAB design allows simple securing and release of the conical ground joint during setup and dismantling, reducing handling effort at the joint. With a nominal capacity of 250 ml and a net weight of 0,257 kg, the unit suits preparative chemistry and dosing tasks where both chemical resistance and visibility of the contents are required. Supplied as one piece from manufacturer Bohlender, this dropping funnel connects to standard ground-joint apparatus used in synthetic and analytical laboratories. The combination of an FEP body and PTFE stopcock components addresses aggressive media that challenge conventional materials, making it a practical choice for precise addition of corrosive or reactive liquids in routine laboratory workflows.
This article is part of Dropping funnels, in Funnels.

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.
