Description
Bottle-top filters with PES membrane are ready-to-use plastic filtration units intended for vacuum-assisted bottle-top filtration. Each filter is fitted with a polyethersulfone (PES) membrane of 50 mm diameter and 0,45 µm pore size, together with a 150 ml upper reservoir for controlled sample processing. This configuration supports clarification and particulate removal of aqueous laboratory solutions where a 0,45 µm PES membrane is specified. The units integrate into standard bottle-top vacuum setups and reduce the need to assemble loose membranes for routine work. Supplied as 12 pieces per pack with a total weight of 1,020 kg, they are practical for laboratories running repeated small-volume filtrations. The 50 mm membrane diameter and 150 ml capacity provide a compact format suited to everyday media, buffer, and solution handling. These bottle-top filters from manufacturer Nalgene form part of ready-to-use plastic filtration systems used in vacuum technology and laboratory filtration. Defined pore size, diameter, and volume make selection straightforward for protocols that require 0,45 µm PES bottle-top filtration at the 150 ml scale.
This article is part of Bottle-top & vacuum filtration units, in Filtration.

Questions about Bottle-top filters with PES-membrane, Ø 50 mm, pore size 0.45 µm, 150 ml
What is this article?
Bottle-top filters with PES-membrane, Ø 50 mm, pore size 0.45 µm, 150 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.
