Product news
Suspended matter in liquid samples has to be removed before injection by filtration, in order to protect the analytical instruments and columns.
Therefore, MACHEREY-NAGEL offers a broad range of colour coded 25, 15, or 3 mm diameter CHROMAFIL® disposable filters, with a solvent resistant polypropylene housing and different membranes like cellulose mixed esters, cellulose acetate, regenerated cellulose, polyamide, PTFE, polyether sulfone, polyester and PVDF.
For a better storage, visual control of fill-up quantity and more safety during transport we offer a new crystal clear packing for the 15 and 25 mm diameter filters.

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.
