Description
CHROMAFIL Xtra PTFE-45/13 is a disposable syringe filter intended for laboratory sample clarification and preparation. The polytetrafluoroethylene (PTFE) membrane provides a pore size of 0,45 µm with a membrane diameter of 13 mm, suitable for retaining coarser particulates before instrumental analysis. A colourless polypropylene housing carries labelling for easy recognition during daily use. The inlet is configured as Luer-Lock and the outlet as a standard Luer connector, ensuring reliable coupling to syringes throughout the filtration step. Packs contain 100 pieces and are available from manufacturer Macherey-Nagel under the CHROMAFIL Xtra PTFE-45/13 designation. PTFE membrane chemistry supports work with organic solvents and chemically demanding samples where broad chemical resistance is required. The 13 mm format is practical for limited sample volumes while maintaining effective filtration performance. These single-use filters fit standard HPLC, GC and general laboratory clean-up procedures, helping laboratories keep sample preparation consistent from run to run without modifying existing protocols or connection hardware.

Questions about CHROMAFIL Xtra PTFE-45/13
What is this article?
CHROMAFIL Xtra PTFE-45/13 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.
