Macherey-Nagel CHROMAFIL Xtra disposable filters GF-100/25 are glass-fibre (GF) syringe filters with a colourless polypropylene (PP) housing. They are designed for efficient filtration of suspended matter from liquid samples and are ideal for high flow rates and pre-filtration of highly viscous or particulate-laden solutions.
Product Features
- Syringe filter CHROMAFIL Xtra, Glass-fibre (GF)
- Polypropylene housing for improved solvent stability compared to acrylate and polystyrene filters
- Shells ultrasonically sealed, not glued, ensuring no extractable components from glues
- Filtration possible in both directions; liquid cannot bypass membranes
- Luer lock on side of entry for safe high-pressure connection
- Luer exit: standard 3 mm and 25 mm filters; minispike luer for 15 mm filters
- Deflector prevents direct impact on the membrane to avoid rupture
- Star-shaped distribution device ensures even liquid distribution and high flow efficiency
- Colour-coded housings: 0.2 µm yellow, 0.45 µm colourless; different membrane types distinguished by colour
- Low dead volume: ~80 µl for 25 mm, 35 µl for 15 mm, 5 µl for 3 mm
Specifications
- Membrane housing made of polypropylene (PP), resistant to most solvents, acids, and bases
- Thick housing rim suitable for laboratory robots (e.g., Benchmate)
- Filter inlet and outlet compatible with CHROMABOND columns using a special adaptor
- Autoclavable at 121°C, 1.1 bar for 30 minutes
- Chromafil Xtra: labelled for method validation and certification
- Colourless plain PP housing with direct imprint for membrane type, diameter, and pore size
- Nominal pore size 1 µm for high flow rates and pre-filtration of viscous or particulate-laden solutions
- Prevents clogging of membranes for subsequent CHROMAFIL filters
Benefits
- Reliable filtration of high particulate or viscous samples
- Low dead volume ensures minimal sample loss
- Durable polypropylene housing suitable for harsh solvents
- Colour coding and labelling enable easy identification of membrane type and size
- Autoclavable for sterility and laboratory safety
Why Choose Macherey-Nagel CHROMAFIL Xtra GF-100/25?
CHROMAFIL Xtra disposable filters provide high-performance pre-filtration, preventing membrane clogging and ensuring efficient, reliable filtration for laboratory samples, even with high particulate loads or viscous liquids.
