Cylindrical dropping funnel 100:2 ml K+H NS 29/32 with pressure equalisation is a graduated laboratory dosing funnel for controlled liquid addition. The cylindrical body carries clear 100:2 ml graduation markings that support precise volume monitoring during reagent transfer. A stopcock with PTFE valve spindle and a 2,5 mm bore provides reliable flow regulation, while the NS 29/32 ground-joint configuration (cone and socket, K+H) ensures compatibility with standard laboratory glassware. The integrated pressure-equalisation path permits smooth operation in closed systems or under reduced pressure without unwanted pressure build-up. This model from manufacturer Witeg is supplied as a pack of 2 pieces; each unit has a net weight of 0,134 kg. The combination of cylindrical form, graduation scale and PTFE spindle makes the funnel suitable for synthesis, extraction and general dosing work that requires accurate, pressure-balanced addition through ground-joint assemblies. Clear visibility of the liquid column and straightforward handling further support everyday laboratory use in dosing-funnel applications.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel cylindrical 100:2ml C+S ST 29/32
What is this article?
Dropping funnel cylindrical 100:2ml C+S ST 29/32 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Labmateriaal.
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.
