Description
25 mm HPLC syringe filter ProFill with polyamide (PA) membrane and 0,45 µm pore size is a disposable filtration device for sample preparation ahead of HPLC and related liquid chromatography workflows. The light-green colour coding supports quick visual identification of the PA / 0,45 µm variant on the bench. Membranes and housing are designed with a low level of extractable compounds, helping to keep background interference low when clarifying solvents, buffers and analytical samples. The filter body is a polypropylene housing fitted with an improved Luer Lock inlet that reduces the risk of leakage and sample loss during syringe-driven filtration. Supplied in packs of 100 pieces from manufacturer Altmann Analytik, these ProFill units suit routine laboratory clarification where a 25 mm diameter and 0,45 µm PA membrane are specified. They integrate readily into standard syringe workflows for particle removal prior to injection, protecting columns and improving chromatographic consistency without adding unnecessary handling steps.
This article is part of Syringe filters, in Filtration.

Questions about 25 mm HPLC syringe filter ProFill, PA, 0.45 µm, light green, 100 pieces/pack
What is this article?
25 mm HPLC syringe filter ProFill, PA, 0.45 µm, light green, 100 pieces/pack is the article on this page. Luminix Health distributes Altmann Analytik 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.
