Description
CHROMAFIL Xtra PVDF-20/13 is a disposable syringe filter equipped with a polyvinylidene difluoride (PVDF) membrane, 0,2 µm pore size and 13 mm membrane diameter. It is built into a colourless polypropylene (PP) housing that is labelled for straightforward grade recognition during sample work-up. The fluid path uses a Luer-Lock inlet and a Luer outlet, matching standard laboratory syringes and downstream fittings for secure, leak-resistant connections. Supplied in packs of 100 pieces, the format suits routine filtration of small to moderate sample volumes before chromatography, spectroscopy or other instrumental methods. PVDF membranes are frequently chosen where chemical resistance and reliable particle retention at 0,2 µm are required. These CHROMAFIL Xtra units from manufacturer Macherey-Nagel are intended for single use, helping laboratories reduce cross-contamination between samples. The compact 13 mm membrane diameter is practical for limited sample amounts, while the labelled PP housing supports fast selection of the PVDF-20/13 specification from mixed filter stocks on the bench.

Questions about CHROMAFIL Xtra PVDF-20/13
What is this article?
CHROMAFIL Xtra PVDF-20/13 is the article on this page. Luminix Health distributes Macherey-Nagel 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.
