Syringe filters for liquid and gas samples
In laboratories, liquid and gas samples often contain particulate impurities that must be removed before analysis. Methods like HPLC, ion chromatography, and gas chromatography require such filtration to ensure quality and uniformity in results, minimizing downtime and equipment maintenance.
Filter liquid and gas samples effectively
Syringe filters are single-use membrane units designed to eliminate particulate impurities from liquid and gas samples before analysis. Merck offers a range of syringe filters like Millex®, Whatman®, and Corning®, each tailored for specific applications. These filters come in sterile and non-sterile forms and feature various membrane compositions and housings to ensure compatibility with different solvents and sample types. Millex® filters, for example, minimize sample loss through low retention volumes and are perfect for HPLC, tissue culture additives, and dissolution assays. They are available in diameters of 4, 13, 25, 33, and 50 mm, with high-quality Millipore® membranes. Whatman® filters include specialized options like Puradisc® for rapid sample filtration, ReZist® for organic solvents, and Anotop® for ion chromatography with low anionic leaching. Corning® filters offer chemical resistance suitable for HPLC with options like nylon, regenerated cellulose, or PTFE membranes.
