Description
Steritop™ bottle top filters are ready-to-use sterile filtration units equipped with a polyethersulfone (PES) membrane at 0,22 µm pore size and a 150 ml process volume. They are intended for vacuum-assisted bottle-top filtration of aqueous media, buffers and similar laboratory solutions where particulate and microbial reduction is required before storage or downstream use. The PES membrane is widely chosen for aqueous filtration because of its favourable flow characteristics and low non-specific binding profile in many media preparations. Each unit is supplied sterile, supporting aseptic workflow practices when transferring filtrate directly into a receiving bottle. The 150 ml format suits smaller batches, pilot media prep and applications that do not require large single-pass volumes. Offered in packs of 12 pc(s), the filters from manufacturer MERCK MILLIPORE fit routine cell-culture, microbiology and general laboratory filtration setups that rely on bottle-top vacuum systems. Consistent membrane specification and sterile presentation help standardise filtration steps across parallel experiments and shared preparation areas without additional assembly of loose filter holders.
This article is part of Bottle-top & vacuum filtration units, in Filtration.

What is this article?
SteritopTM bottle top filters, PES-membrane, sterile, 0.22 µm, 150 ml is the article on this page. Luminix Health distributes MERCK MILLIPORE 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.
