Macherey-Nagel 729219.400 CHROMAFIL Xtra disposable filter PVDF-45/25 PVDF, Pore size 0.45um, 25mm diameter, non sterile, Housing colourless PP-case, labelled, pack of 400

Syringe filter CHROMAFILTM, Polyvinylidenfluoride (PVDF), CHROMAFIL syringe filters are used for filtration of suspended matter from liquid samples. Advantages: HPLC-Certificationavailable on the internet, Polypropylene housing, better solvent stability compared to acrylate and polystyrene filters, Shells ultrasonically sealed, not glued, no extractable components from glues, Filtration in both directions possible, the liquid cannot bypass the membranes, Luer lock on side of entry, safe connection on the ''high pressure'' side, Luer exit, standard luer for 3mm and 25mm filters, minispike luer with low dead volume and small OD for 15mm filters, Deflector, the stream of liquid is broken and distributed, and does not directly hit the membrane preventing rupture of the membrane, Star-shaped distribution device, the liquid is evenly distributed to the whole membrane surface: this results in a better utilisation of the total area; filter is not rapidly clogged; high flow efficiency, Colour coded with colourless upper housing. colourless; the different membrane types are distinguished by different colours, Low dead volume, ~80ul for 25mm, 12ul for 15mm, 5ul for 3mm. Specifications, The membrane housing consists of polypropylene (PP). This material is very resistant towards most solvents and has a very low extractable substances content. Thus it can be used with almost all solvents, acids and bases. The especially thick rim of the housing is ideal for use with laboratory robots (e.g. BenchmateTM). Filter inlet and filter outlet can be fitted to the CHROMABOND columns for selective sample preparation with the aid of a special adaptor. ChromafilTMXtra: Labelled for method validation and certification. Colour-free plain polypropylene housing, Imprint for direct identification of the membrane type, diameter and pore size. Hydrophilic membrane, for polar and nonpolar solutions, water-soluble oligomers and polymers like proteins binding capacity for proteins 82µg/25mm filter
