Macherey-Nagel CHROMAFIL Xtra Disposable Filter MV-20/25 Cellulose Mixed Esters, 0.2 µm, 25 mm, colourless PP-case, labelled, pack of 100 is designed for efficient and certified filtration of suspended matter from liquid samples. HPLC-certification is available online for quality assurance.
Product Features
- CHROMAFIL syringe filters for reliable filtration of suspended matter from liquid samples
- HPLC-certification available online for quality compliance
- Polypropylene housing offers better solvent stability than acrylate and polystyrene filters
- Shells ultrasonically sealed, not glued – ensuring no extractable components from adhesives
- Supports filtration in both directions; liquid cannot bypass the membranes
- Luer lock on side of entry 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 and small OD for 15 mm filters
- Deflector breaks and distributes the liquid stream, preventing direct impact and rupture of the membrane
- Star-shaped distribution device evenly distributes liquid to the whole membrane surface for better utilization, less clogging, and higher flow efficiency
- Colour coded design: 0.2 µm filters have yellow upper housing, 0.45 µm filters are colourless; different membrane types distinguished by unique colours
- Low dead volume: approx. 80 µl for 25 mm, 35 µl for 15 mm, and 5 µl for 3 mm filters
- CHROMAFIL Xtra: labelled for method validation and certification, with imprint showing membrane type, diameter, and pore size
- Colour-free plain polypropylene housing for easy identification
- Hydrophilic membrane recommended for aqueous or polar organic sample filtrations
Specifications
- Membrane housing made of polypropylene (PP), highly resistant to most solvents
- Very low content of extractable substances, ensuring sample purity
- Compatible with almost all solvents, acids, and bases
- Especially thick rim design suitable for use with laboratory robots (e.g., Benchmate)
- Filter inlet and outlet can be fitted to CHROMABOND columns with special adaptor for selective sample preparation
- All filters can be autoclaved at 121°C and 1.1 bar for 30 minutes
Benefits
- Ensures reproducible and safe sample preparation for analytical workflows
- Prevents clogging and membrane rupture, increasing efficiency
- Highly compatible with solvents, acids, and bases for versatile laboratory use
