Description
Filter units with PES membrane combine a 50 mm diameter polyethersulfone membrane at 0,2 µm pore size with a 150 ml capacity for ready-to-use vacuum filtration. These plastic filtration units support clarification and sterile-grade style filtration steps in media preparation, buffer work, and general laboratory sample processing where bottle-top or standalone filter systems are preferred. Each pack contains 12 pc(s) with a total weight of 1,133 kg, suited to routine throughput in research and quality-control environments. The PES membrane is widely chosen for aqueous solutions because of its low protein-binding character and consistent flow behaviour under vacuum. Offered from manufacturer Nalgene, the units fit standard vacuum-filtration workflows without additional membrane assembly. Clear dimensional and pore-size specification (Ø 50 mm, 0,2 µm, 150 ml) helps match the filter to protocol requirements for particle removal and solution preparation. Ideal for laboratories standardising disposable filtration hardware across multiple benches.
This article is part of Bottle-top & vacuum filtration units, in Filtration.

Questions about Filter units with PES-membrane, Ø 50 mm, pore size 0.2 µm, 150 ml, 12 unit(s)
What is this article?
Filter units with PES-membrane, Ø 50 mm, pore size 0.2 µm, 150 ml, 12 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.
