Description
PES combination syringe filter with glass fibre pre-filter 25 mm, 0,22 µm / GF92 1 µm provides dual-stage filtration for laboratory sample preparation requiring finer membrane retention. The polyethersulfone membrane at 0,22 µm is backed by a GF92 glass fibre pre-filter of 1 µm, enabling greater sample throughput by capturing larger particles before they reach the final membrane. The 25 mm housing features a Luer Lock interface for reliable syringe connection. These unsterile filters are intended for aqueous and compatible solvent samples in analytical and research settings, including preparation steps ahead of chromatography or other sensitive measurements. From manufacturer Berrytec, the combination format streamlines workflow by combining pre-filtration and final filtration in one unit, helping maintain flow rate when handling particle-rich or moderately viscous matrices. Suitable for routine QC, method development and general laboratory clarification tasks where a 0,22 µm PES barrier with integrated glass fibre protection is preferred.
This article is part of Syringe filters, in Filtration.

Questions about PES combi-syringe filter with glassfiber prefilter 25mm, 0,22µm / GF92 1µm
What is this article?
PES combi-syringe filter with glassfiber prefilter 25mm, 0,22µm / GF92 1µm 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.
