Description
PES Filter Holder LF3a 300 ml with Bottle Adapter is a vacuum filtration unit engineered for direct collection into laboratory bottles. The assembly features a 300 ml PES funnel with 47 mm filter diameter, a polycarbonate filter base, a polypropylene intermediate piece and a PP lid set, completed by a bottle adapter and supplied without membrane filters. This configuration allows filtered filtrate to pass straight into a receiving bottle, reducing transfer steps and contamination risk. Manufactured by Witeg, the LF3a holder is intended for Witt-style vacuum filtration of aqueous samples and many routine laboratory solvents. Its compact build (net weight 0,3 kg) supports easy positioning on the bench and straightforward disassembly for cleaning or filter replacement. Applications span microbiology media preparation, environmental sample processing, buffer clarification and general analytical workflows. The modular PES–PC–PP construction provides a durable, chemically resistant platform for daily vacuum filtration tasks in research, quality-control and teaching laboratories that require reliable 47 mm disc filtration with bottle collection.

Questions about PES filter holder LF3a 300ml with bottle adapter
What is this article?
PES filter holder LF3a 300ml with bottle adapter is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Lab consumables.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
