Description
Dosing funnel for powder 50 ml NS 29/32 is a solid-material dosing funnel engineered for controlled addition of powders in laboratory glassware systems. Featuring core and sleeve joints of NS 29/32, the 50 ml unit includes a cooled lower part and a vertical feed screw that enables steady conveyance of solid reagents. Net weight is 0,344 kg. The cooled base helps manage temperature-sensitive powders during transfer into reaction vessels or multi-neck flasks fitted with matching NS 29/32 connections. Manufactured by Witeg and supplied as 1 pc, this dosing funnel supports precise solid handling in organic synthesis, formulation work, and analytical sample preparation. The vertical Förderschnecke design promotes uniform powder flow while the ground-joint interfaces ensure leak-tight integration with standard laboratory apparatus. It is particularly useful in setups where gradual introduction of solids is required without interrupting the closed system. Overall the construction offers a reliable means of powder dosing within research and process-development laboratories that rely on NS 29/32 glassware.

Questions about Dosing funnel for powder 50ml NS29/32
What is this article?
Dosing funnel for powder 50ml NS29/32 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Powder funnels, inside Funnels, in Labware.
A powder funnel has a wide bore and a short, steep cone so a solid does not bridge on the way into a bottle. A liquid funnel's narrow stem is exactly the wrong tool for a powder.
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.
