Inline filters and precolumn filters

Product / Chromatography

Inline filters protect sensitive equipment from particulate contamination (between pump and injection valve/autosampler), and precolumn filters protect the column inlet: analytical and semi-preparative versions, Inline MicroFilters, Mini MicroFilters and Precolumn MicroFilters. Some have a metal-free PEEK-based biocompatible flow path; replacement frits are sold separately. Precolumn filters use smaller thru-holes and frit diameters to minimise effects on peak shape.
