Description
Nalgene™ 25 mm sterile syringe filters with PES membrane are intended for filtration of sample volumes from 10 to 100 mL in cell-culture and related laboratory applications. Each unit features a polyethersulfone (PES) membrane with 0,45 µm pore size in a polypropylene housing, providing a compact syringe-filter format for sterilisation and clean-up steps. Primary applications include sterilisation and purification of cell culture media, serum and additives, where PES membrane performance supports aqueous biological fluids under sterile handling conditions. The sterile presentation addresses workflows that demand a controlled barrier in addition to defined pore retention. Filters are supplied as a case of 50, matching moderate batch sizes typical of media preparation and additive filtration. These Nalgene™ 25 mm syringe filters from manufacturer Thermo Scientific - Laboratory Plastics unite PES membrane chemistry with a polypropylene housing for reliable syringe-driven processing. The 25 mm diameter and 0,45 µm rating align with standard laboratory protocols for media and serum clarification, helping laboratories maintain consistent filtration practice across routine sterile sample preparation tasks.

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.
