Description
PTFE syringe filter hydrophilic 4 mm, 0,45 µm is a miniature laboratory syringe-tip filter for clarification of small aqueous sample volumes. It features a hydrophilic PTFE membrane with a 4 mm diameter and a pore size of 0,45 µm, allowing aqueous solutions to wet the membrane surface without the extensive pre-wetting often needed for hydrophobic PTFE. The unit is equipped with a Luer Lock connection for reliable coupling to standard syringes during manual filtration steps. Supplied non-sterile, these filters are intended for general laboratory sample preparation rather than sterile applications. Packaged as 1000 pieces from manufacturer Berrytec, the compact format supports efficient processing of limited sample amounts in analytical and research environments. Hydrophilic PTFE provides chemical durability together with practical wettability for water-based media commonly handled in the laboratory. Typical applications include particulate removal from aqueous aliquots prior to instrumental analysis, clarification of buffers and reagents, and routine filtration tasks where a 0,45 µm pore size and small membrane diameter help minimise sample loss while maintaining straightforward syringe-based handling in everyday laboratory workflows.
This article is part of Syringe filters, in Filtration.

Questions about PTFE syringe filter hydrophilic 4mm, 0.45µm
What is this article?
PTFE syringe filter hydrophilic 4mm, 0.45µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Syringe filters, inside Filtration, in Lab consumables.
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.
