Description
Nalgene™ 25 mm syringe filter with polyethersulfone (PES) membrane and 0,2 µm pore size is a sterile disposable unit designed for clarifying and sterilising aqueous laboratory samples in the 10 to 100 ml volume range. The PES membrane offers low protein binding and high flow for cell-culture media, serum, additives and similar solutions, while the polypropylene housing provides chemical resistance and secure Luer connections during syringe-driven filtration. Each filter is intended for single use, supporting clean sample preparation without the need for reusable holders or autoclaving between runs. Typical laboratory applications include sterilisation and purification of media and supplements prior to cell culture, as well as general particulate removal from aqueous reagents. Supplied in a case of 50 filters, the format suits medium-throughput workflows in research, biotech and quality-control settings. These Nalgene™ syringe filters from manufacturer Thermo Scientific combine a 25 mm diameter membrane with a compact housing that minimises hold-up volume and waste. The combination of sterile PES membrane, defined 0,2 µm porosity and robust polypropylene construction makes the units a practical choice for routine sterile filtration of small to moderate sample volumes at the bench.

Questions about Nalgene™ Sterile Syringe Filters
What is this article?
Nalgene™ Sterile Syringe Filters is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
