Description
Steritop™ bottle top filters are sterile, ready-to-use bottle-top filtration devices featuring a polyethersulfone (PES) membrane with 0,22 µm pore size and a 250 ml working volume. They support vacuum filtration of aqueous laboratory media, buffers and related solutions when a sterile filtrate is needed for cell culture, microbiology or general wet-lab preparation. The PES membrane is commonly selected for aqueous streams because it combines efficient flow with low binding behaviour for many media components. Sterile supply allows the filter to be placed directly onto a compatible receiving bottle, helping maintain aseptic technique during media and buffer clarification. The 250 ml capacity balances batch size and handling convenience for mid-scale preparations that exceed small aliquots yet do not require large-volume systems. Packaged as 12 pc(s), these units from manufacturer MERCK MILLIPORE integrate into standard vacuum bottle-top filtration workflows used across research, quality-control and production-support laboratories. Uniform pore rating and sterile presentation promote reproducible filtration steps from run to run without assembling separate holders or membranes.
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, 250 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.
