Description
Dropping funnel 100 ml NS 29/32 is a cylindrical, graduated laboratory dosing funnel for controlled addition of liquids in synthesis, extraction and general preparative chemistry. It offers a 100 ml working capacity with graduation marks every 2 ml, enabling clear volume tracking during dosing operations. Cone and socket joints in NS 29/32 size provide secure connection to matching ground-joint glassware assemblies. Flow control is achieved with an NS stopcock plug featuring threaded stopcock security, which helps keep the stopcock firmly seated under normal laboratory handling. The stopcock bore measures 2,5 mm, supporting smooth and consistent reagent delivery. Manufactured according to DIN 12567, this dropping funnel from manufacturer Witeg follows recognised dimensional standards for ground-joint dosing funnels. Net weight is 0,126 kg, combining a practical mid-range capacity with easy bench handling. Typical applications include dropwise reagent addition, phase separations and controlled transfers in organic and inorganic workflows. The cylindrical body gives a stable working profile and facilitates cleaning between experiments. Supplied as 2 pieces for ready use in standard NS 29/32 setups found in research and quality-control laboratories.

Questions about Dropping funnels 100ml ST 29/32
What is this article?
Dropping funnels 100ml ST 29/32 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.
