Beschrijving
Screw filter 30 ml is a modular laboratory filtration assembly intended for small-volume solid-liquid separations. The unit is supplied with funnel, attachment and two seals, yet without a filter plate, so users can select the porosity that matches their protocol. Filter plate diameter is 24 mm and the thread measures 28 mm, ensuring compatibility with common laboratory glassware. Manufactured by Witeg, this screw filter supports vacuum or gravity filtration in analytical chemistry, organic work-ups and sample preparation. Its compact 30 ml capacity suits micro-scale reactions, residue collection and routine clarification steps where minimal hold-up volume is advantageous. The glass construction provides chemical resistance to a wide range of solvents and aqueous media. Net weight of only 0,04 kg keeps the assembly light and easy to handle on the bench. Researchers value the open design that allows rapid plate exchange and thorough cleaning between runs. Ideal for teaching laboratories and research groups that require flexible frit-based filtration hardware without fixed porosity constraints.

Questions about SCREW FILTER 30 ML, WITH FUNNEL, HEAD,
What is this article?
SCREW FILTER 30 ML, WITH FUNNEL, HEAD, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Trechters, in Labmateriaal.
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.
