Description
PTFE syringe filters with a hydrophobic membrane, 4 mm diameter and 0,45 µm pore size support laboratory filtration of organic solvents and aggressive media during sample preparation. The polytetrafluoroethylene membrane provides wide chemical compatibility, and the hydrophobic surface is suited to non-aqueous solutions and comparable filtration tasks. A Luer Lock interface ensures a firm connection to standard syringes and reduces the chance of leakage when pressure is applied by hand. Delivered non-sterile in packs of 100 pieces from manufacturer Berrytec, the small 4 mm design is practical for limited sample volumes and applications that benefit from low hold-up volume. Common uses include particle removal before chromatographic or spectroscopic measurement, solvent filtration and safeguarding analytical equipment against particulates. The 0,45 µm pore size offers efficient retention of fine debris while maintaining workable flow for everyday laboratory procedures. These hydrophobic PTFE syringe filters are a compact choice for benches that need reliable chemical resistance in a ready-to-use Luer Lock format.
This article is part of Syringe filters, in Filtration.

Questions about PTFE syringe filter hydrophobic 4mm, 0.45µm
What is this article?
PTFE syringe filter hydrophobic 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.
