Macherey-Nagel Chromafil® Colourless/Orange Polytester (PET) Non-Sterile Syringe Filters with Mini Tip Outlet; Pore Size 0.45 µm
Item No.
4003398
CHROMAFIL® syringe filters are used for filtration of suspended matter from liquid samples. HPLC-Certification available 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: this prevents 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; the filter is not rapidly clogged up; high flow efficiency. Colour coded: Filters with 0.2µm pores have a yellow upper housing; for filters with 0.45µm pores this is colourless; the different membrane types are distinguished by different colours. Low dead volume: ~80µl for 25mm; 12µl for 15mm; 5µl 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 (see table). The especially thick rim of the housing is ideal for use with laboratory robots (e.g. Benchmate™). Filter inlet and filter outlet can be fitted to the CHROMABOND® columns for selective sample preparation with the aid of a special adaptor. All filters can be autoclaved at 121°C and 1.1bar for 30min. Hydrophilic membrane for polar as well as non-polar solvents. The HPLC filter; especially suited for mixtures of water and organic solvents; for TOC/DOC determination; not cytotoxic; does not inhibit the growth of microorganisms and higher cells. Polyester filter with integrated glass fibre prefilter (GF/PET): recommended for solutions with a high load of particulate matter or for highly viscous solutions.
