Description
PVDF syringe filters, hydrophilic, combine a polyvinylidene fluoride membrane with a compact 4 mm housing for small-volume sample clarification and sterile filtration. Each unit offers a 0,22 µm pore size suited to bacterial retention and particulate removal ahead of HPLC, UHPLC, ion chromatography or microbiological workflows. The hydrophilic PVDF surface wets readily with aqueous and many mixed aqueous–organic media, reducing the need for pre-wetting steps common with hydrophobic membranes. Filters are supplied sterile in a pack of 100 pieces, supporting aseptic sample preparation in pharmaceutical, biotech and clinical research laboratories. Manufactured by Membrane Solutions, these syringe filters fit standard Luer connections on disposable syringes for rapid, single-use filtration. The small 4 mm diameter minimises hold-up volume, which is advantageous when only limited sample is available. Laboratories specifying 0,22 µm sterile PVDF benefit from consistent membrane chemistry for aqueous buffers, culture media and light organic blends where low extractables and reliable flow are required.

Questions about PVDF syringe filters, hydrophilic — 0,22 µm — Ø 4 mm
What is this article?
PVDF syringe filters, hydrophilic — 0,22 µm — Ø 4 mm is the article on this page. Luminix Health distributes Membrane Solutions for laboratory use. It sits in Filtres seringue, inside Filtration, in Consommables.
A syringe filter is a membrane in a plastic housing on a Luer fitting. Pore size, membrane polymer and diameter are the three choices. 0.2 µm is the sterilising and the HPLC-particle cut. 0.45 µm is the coarser clarification. Aqueous and solvent-resistant membranes are different polymers.
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.
