Description
Bottle-top filters with PES membrane are ready-to-use plastic filtration units designed for vacuum bottle-top filtration at medium sample volumes. Each unit is equipped with a polyethersulfone (PES) membrane of 75 mm diameter and 0,45 µm pore size, combined with a 500 ml upper reservoir for convenient handling of aqueous laboratory solutions. This format supports clarification and particulate removal where a 0,45 µm PES membrane and larger working volume are needed. The filters fit standard bottle-top vacuum systems and help streamline routine filtration without manual membrane mounting. Supplied in packs of 12 pieces with a total weight of 1,650 kg, they are suited to laboratories performing repeated filtrations at the 500 ml scale. The 75 mm membrane diameter provides increased filtration area relative to smaller bottle-top units, while the 500 ml capacity accommodates typical media and buffer volumes. These bottle-top filters from manufacturer Nalgene are part of ready-to-use plastic filtration systems used in vacuum technology and laboratory filtration. Pore size, diameter, and volume are clearly defined to support selection for 0,45 µm PES bottle-top applications.

Questions about Bottle-top filters with PES-membrane, Ø 75 mm, pore size 0.45 µm, 500 ml
What is this article?
Bottle-top filters with PES-membrane, Ø 75 mm, pore size 0.45 µm, 500 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.
