Description
Filter units with PES membrane are ready-to-use plastic filtration units for laboratory vacuum and bottle-top filtration workflows. Each unit combines a PES membrane of 50 mm diameter with a pore size of 0,2 µm and a 250 ml working volume, giving a clearly defined geometry for routine sample and media handling. The configuration matches established bottle-top filter systems used in research, quality control and general laboratory practice where vacuum-assisted filtration is required. Units are supplied in a pack of 12 pc(s), supporting continuous bench use without frequent reordering. Total pack weight is 3,000 kg according to the stated unit data. These filter units from manufacturer Nalgene sit within the range of ready-to-use plastic filtration units intended for vacuum technology and filtration by means of bottle-top filters and systems. Laboratories can select the 50 mm, 0,2 µm, 250 ml format when membrane diameter, pore size and volume must align with existing protocols. The PES membrane construction and fixed pack quantity provide a practical, catalogue-consistent option for everyday filtration tasks that rely on defined membrane area and retention characteristics.

Questions about Filter units with PES-membrane, Ø 50 mm, pore size 0.2 µm, 250 ml, 12 unit(s)
What is this article?
Filter units with PES-membrane, Ø 50 mm, pore size 0.2 µm, 250 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 Consommables.
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.
