Description
Reusable bottle-top filter holders made of PSF are intended for vacuum filtration on laboratory bottles with a 45 mm thread. With a 500 ml holder capacity, the unit supports bottle-top filtration tasks such as sample clarification, media preparation, and general removal of particulates from aqueous laboratory liquids. The product is supplied as 1 pc(s) and weighs 0,362 kg, providing a compact upper assembly that couples directly to compatible 45 mm threaded receiving bottles. From manufacturer Nalgene, these reusable PSF holders fit into vacuum technology and ready-to-use plastic filtration workflows where a durable bottle-top interface is required. Operators can equip the holder with appropriate membrane filters for successive filtrations in line with laboratory procedures. The 45 mm thread matches widely used wide-mouth bottle closures, helping standardise filtration setups across research, teaching, and quality-control benches. This configuration is suited to laboratories that prefer reusable plastic filter holders instead of fully disposable bottle-top units for routine vacuum filtration.
This article is part of Bottle-top & vacuum filtration units, in Filtration.

Questions about Reusable bottle-top filter holders, PSF, for thread 45 mm, 500 ml, 1 unit(s)
What is this article?
Reusable bottle-top filter holders, PSF, for thread 45 mm, 500 ml, 1 unit(s) is the article on this page. Luminix Health distributes Nalgene 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.
