Vacuum-driven filters are essential consumables for sample and solvent pre-filtration prior to HPLC and GC analysis. They effectively remove particulate contaminants from liquid samples and mobile phases to safeguard high-performance chromatography instruments and ensure reliable analytical data.
Impurities contained in samples and solvents may scratch liquid chromatography pumps, block injection valves, pipelines and chromatographic columns, and create unwanted interference peaks that compromise detection results. By pre-filtering liquids with our vacuum-driven filters, users can minimize pump wear, prevent column clogging, reduce impurity interference on chromatograms, and significantly enhance the sensitivity and accuracy of qualitative & quantitative testing.
✅ Multiple optional filter membrane materials to match diverse sample matrices ✅ Designed for sample & solvent pre-filtration before HPLC and GC pretreatment ✅ Standard Luer connector for convenient connection and operation ✅ Ultra-clean polypropylene housing with low solubility, ideal for trace analysis ✅ Low residual volume to save precious sample ✅ Cost-effective and eco-friendly
Q: Why use vacuum-driven filters for HPLC/GC? A: Particulate impurities in solvents and samples easily damage pumps, valves and chromatography columns. Vacuum filtration removes particles in advance to protect expensive analytical instruments and eliminate impurity interference on chromatograms.
Q: What material is the housing? A: The filter shell is made of ultra-clean polypropylene with low solubility, which will not introduce extra contaminants and meets the requirements of trace analysis.
