Description
CHROMAFIL Xtra PTFE-20/13 is a disposable syringe filter for sample preparation in analytical and research laboratories. Its polytetrafluoroethylene (PTFE) membrane has a pore size of 0,2 µm and a membrane diameter of 13 mm, supporting fine particulate removal ahead of chromatographic or spectroscopic work. The colourless polypropylene housing is labelled for quick identification at the bench. Inlet geometry is Luer-Lock and the outlet is a standard Luer fitting, allowing secure connection to common laboratory syringes during filtration. Offered in packs of 100 pieces from manufacturer Macherey-Nagel, the CHROMAFIL Xtra PTFE-20/13 format suits small-volume samples where PTFE chemical resistance is advantageous for organic solvents and demanding matrices. The compact 13 mm membrane diameter keeps hold-up volume modest while still delivering effective filtration. These single-use units integrate readily into HPLC, GC and general clean-up workflows without changing established sample-handling steps. Clear housing labelling and standardised Luer interfaces help maintain consistent, reproducible preparation across routine series and method development alike.

Questions about CHROMAFIL Xtra PTFE-20/13
What is this article?
CHROMAFIL Xtra PTFE-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.
