Macherey-Nagel CHROMAFIL Xtra disposable PA (Polyamide/Nylon) syringe filters are designed for efficient filtration of suspended matter from liquid samples. These filters provide excellent solvent stability, reliable performance, and are suitable for use in HPLC applications. The polypropylene housing ensures high chemical resistance and minimal extractables, making them ideal for use with most solvents, acids, and bases.
Product Features
- Used for filtration of suspended matter from liquid samples
- HPLC-certified, with certification available online
- Polypropylene housing resistant to most solvents and acids/bases
- Better solvent stability compared to acrylate and polystyrene filters
- Ultrasonically sealed shells, not glued – no extractable components from glues
- Filtration in both directions possible; liquid cannot bypass membranes
- Luer lock inlet for safe connection on the high-pressure side
- Luer exit: standard luer for 3 mm and 25 mm filters; minispike luer with low dead volume for 15 mm filters
- Deflector prevents direct stream impact on the membrane to avoid rupture
- Star-shaped distribution device ensures uniform liquid distribution, better area utilization, prevents rapid clogging, and provides high flow efficiency
- Colour-coded housing: 0.2 µm pores have yellow upper housing, 0.45 µm pores are colourless; different membrane types distinguished by colours
- Low dead volume: ~80 µl (25 mm), 35 µl (15 mm), 5 µl (3 mm)
- Labelled for method validation and certification
- Colour-free plain polypropylene housing with imprint for direct identification of membrane type, diameter, and pore size
- Hydrophilic PA membrane, ideal for medium polar organic/aqueous liquids
Specifications
- Membrane housing material: Polypropylene (PP)
- Highly resistant to most solvents, acids, and bases
- Very low extractable substances content
- Thick rim ideal for laboratory robots (e.g., Benchmate)
- Filter inlet and outlet compatible with CHROMABOND columns via special adaptor
