Description
Cylindrical dropping funnel 100 : 2 ml K+H NS 14/23 with pressure equalisation, graduated is a precision laboratory dosing funnel manufactured to DIN 12567. The cylindrical body is graduated and fitted with pressure-equalisation tubing, an NS stopcock plug secured by a threaded stopcock retainer, and ground joints (cone and socket) of size NS 14/23. The stopcock bore measures 2,5 mm, allowing controlled addition of reagents under equalised pressure. This configuration from manufacturer Witeg is intended for accurate volumetric delivery in synthesis, titration support and general preparative chemistry. The 100 : 2 ml graduation scale supports clear volume reading during addition. Supplied in packs of 2 pieces, the funnel is ready for immediate incorporation into standard ground-joint glassware trains. Net weight is 0,125 kg per unit. The combination of pressure equalisation, secure stopcock retention and standardised NS 14/23 joints ensures reliable, leak-resistant operation in both atmospheric and slightly pressurised setups common in modern laboratories.

Questions about Dropping funnels cylindrical 100: 2ml C+S ST 14/23
What is this article?
Dropping funnels cylindrical 100: 2ml C+S ST 14/23 is the article on this page. Luminix Health distributes Witeg 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.
