Macherey-Nagel Chromafil disposable syringe filters are designed for reliable filtration of suspended matter from liquid samples. Featuring glass-fibre (GF) membranes with a nominal pore size of 1.00 µm, they allow higher flow rates and are ideal for solutions with high particulate loads or highly viscous samples. Certified for HPLC applications, they can also serve as prefilters for other CHROMAFIL filters, preventing membrane clogging.
Product Features
- Used for filtration of suspended matter from liquid samples
- HPLC certification available online
- Polypropylene housing with better solvent stability than acrylate or polystyrene
- Shells ultrasonically sealed, not glued – no extractable glue components
- Allows filtration in both directions; liquid cannot bypass the membranes
- Luer lock on entry side ensures safe connection for high-pressure use
- Luer exit: standard luer for 3 mm and 25 mm filters, minispike luer with low dead volume for 15 mm filters
- Deflector breaks and distributes liquid stream to prevent membrane rupture
- Star-shaped distribution device ensures full membrane use, prevents clogging, and improves flow efficiency
- Colour-coded housings: 0.2 µm = yellow, 0.45 µm = colourless; membrane types differentiated by housing colour
- Low dead volume: ~80 µl (25 mm), 35 µl (15 mm), 5 µl (3 mm)
- Chromafil Xtra: plain polypropylene housing labelled for method validation and certification
- Imprint identifies membrane type, diameter, and pore size
- Inert glass-fibre membrane with 1.00 µm pore size allows higher flow rates
- Recommended for solutions with high particulate matter or highly viscous solutions (e.g., soil samples, fermentation broths)
- Can be used as a prefilter to prevent plugging of other CHROMAFIL membranes
- Autoclavable at 121°C and 1.1 bar for 30 minutes
- Filter diameter: 25 mm
- Pore size: 1.00 µm
- Pack quantity: 100 filters
Specifications
