Description
qpore® membrane filters in pure polyethersulfone (PES), non-sterile, with a 0,22 µm pore size and 47 mm diameter, combine an asymmetric pore structure with excellent laboratory performance. Among common membrane materials, this PES design offers the highest flow rate while keeping protein and active-substance binding low, making the filters well suited to life-science filtration. High thermal stability further allows filtration of hot liquids. Hydrophilic PES discs wet readily and support efficient processing of aqueous and related samples where throughput and minimal analyte retention are important. Supplied in packs of 200 pieces from manufacturer neolab - Labor, they fit clarification and preparatory steps in research, biotech and quality-control environments. Select these qpore® PES membranes when fast flow, low binding and the option to handle elevated liquid temperatures are required in a compact 47 mm format.
This article is part of Membrane filters, in Filtration.

Questions about qpore® Membranfilter, PES, unsteril, 0,22 µm, Ø 47 mm
What is this article?
qpore® Membranfilter, PES, unsteril, 0,22 µm, Ø 47 mm is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
