Description
Bottle-top filters with PES membrane are ready-to-use plastic filtration units for laboratory vacuum filtration. Each unit combines a polyethersulfone (PES) membrane of 90 mm diameter with a pore size of 0,2 µm and a 1000 ml working volume, matching the stated bottle-top filter format for aqueous sample handling. The PES membrane geometry supports clarification and particulate retention steps typical of bottle-top filter systems used on vacuum lines. These filters belong to the ready-to-use plastic filtration unit category within vacuum technology and filtration workflows, where upper bottle-top assemblies are mounted for direct transfer into receiving vessels. Offered in a pack of 12 pc(s) from manufacturer Nalgene, the set suits laboratories that process larger media or buffer volumes through a defined 0,2 µm barrier. Pack weight is 1,000 kg according to the product data. The combination of 90 mm membrane area, 0,2 µm pore size and 1000 ml capacity gives a clear specification profile for routine bottle-top filtration without additional accessories beyond a compatible vacuum source and receiver.
This article is part of Bottle-top & vacuum filtration units, in Filtration.

Questions about Bottle-top filters with PES-membrane, Ø 90 mm, pore size 0.2 µm, 1000 ml
What is this article?
Bottle-top filters with PES-membrane, Ø 90 mm, pore size 0.2 µm, 1000 ml 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.
