Description
Filter units with SFCA membrane are ready-to-use plastic filtration units configured for laboratory vacuum filtration. This version pairs a surfactant-free cellulose acetate (SFCA) membrane of 50 mm diameter and 0,2 µm pore size with a 250 ml volume, offering a larger working capacity than the 150 ml SFCA units in the same family. The 50 mm membrane and 0,2 µm rating support clarification and particle-retention steps on vacuum lines, while the 250 ml format suits moderate sample or media volumes. Classification covers vacuum technology and filtration as well as ready-to-use plastic filtration units and bottle-top filter systems. Units are packed as 12 pc(s) from manufacturer Nalgene for routine laboratory supply. Pack weight is listed as 2,200 kg. All core parameters—SFCA membrane, 50 mm diameter, 0,2 µm pore size and 250 ml capacity—are taken directly from the manufacturer description, providing a straightforward specification set for vacuum-assisted filtration workflows.
This article is part of Bottle-top & vacuum filtration units, in Filtration.

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