Pre-filters and filter holders are indispensable components for precise sample preparation in modern laboratory analytics. These specialized filtration solutions ensure reliable removal of particles and contaminants before downstream analytical procedures such as UHPLC, HPLC and GC technology.

Diverse material options for different applications

The product range includes filter holders made from various chemically resistant plastics. Polycarbonate (PC) offers excellent transparency and mechanical strength, while polyoxymethylene (POM) convinces with high rigidity and low water absorption. Polysulfone (PSU) is characterized by exceptional temperature resistance, polypropylene (PP) by universal chemical compatibility. For highest requirements, filter holders made from polytetrafluoroethylene (PTFE) and perfluoroalkoxy (PFA) are available, offering nearly universal chemical resistance.

Specialized pre-filters for optimal sample preparation

Disposable filter attachments with hydrophilic properties enable efficient filtration of aqueous and solvent-containing samples. Glass fiber reinforced filter membranes ensure fast flow rates while maintaining high particle retention. Hydrophobic variants are particularly suitable for organic solvents and aggressive chemicals. The integration of Luer-Lock connections enables secure and leak-free connection to syringes and other laboratory equipment.

High-pressure inline filters for demanding applications

Inline filters made from polyetheretherketone (PEEK) are specifically designed for high-pressure applications in HPLC analytics. These filters are installed directly before chromatographic columns and protect them from particles and contaminants. Polyvinylidene fluoride (PVDF) offers excellent chemical resistance to polar and non-polar solvents.
