Description
Filter units with PES membrane are ready-to-use plastic filtration units intended for laboratory vacuum and bottle-top filtration. Each unit is equipped with a polyethersulfone (PES) membrane measuring 90 mm in diameter and offering a pore size of 0,2 µm, paired with a 1000 ml working volume for larger sample handling. These filtration units support routine clarification and preparation steps in research, analytical, and quality-control laboratories. The PES membrane format is applied in aqueous filtration workflows within vacuum technology setups. Available as a pack of 12 pieces from manufacturer Nalgene, the units arrive as complete plastic filtration assemblies suited to established bottle-top filter practices. The pack has a total weight of 5,000 kg, convenient for stocking shared laboratory benches and media preparation areas. By combining a defined pore rating, fixed membrane diameter, and practical 1000 ml capacity, the product helps standardise filtration protocols across multiple operators and experiments within ready-to-use plastic filtration unit workflows.

Questions about Filter units with PES-membrane, Ø 90 mm, pore size 0.2 µm, 1000 ml, 12 unit(s)
What is this article?
Filter units with PES-membrane, Ø 90 mm, pore size 0.2 µm, 1000 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.
