Product news

CHROMAFIL® Xtra filters are ideal for GC, HPLC and UHPLC sample purification and are labelled for method validation and certification. The range of CHROMAFIL® disposable filters has now been enlarged by the new CHROMAFIL® Xtra filters, a range of 25 mm diameter filters with different membranes.


Special features of all CHROMAFIL® Xtra filters:

- Different membrane types to meet multiple filtration needs
- Labelled with membrane type and pore size for method validation and certification
- Low levels of extractable compounds ensure reliable analyses
- Superior chromatography column protection helps extend column life
- Fast flow geometry for easy and faster filtration
- Low hold-up volume for maximum filtrate recovery
- HPLC certified for reliable quality
- Designed to be compatible for use with SOTAX dissolution systems


CHROMAFIL® filters are tested and inspected to provide high quality syringe filters.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.
