Mini-UniPrep G2 is an all-in-one syringeless filter with a borosilicate glass chamber. It replaces syringe filters for autosampler-supported UHPLC/HPLC sample preparation with easier handling and fewer consumable components. Features an integrated autosampler vial, plunger with attached filter membrane, and septum/cap Borosilicate glass vials eliminate plastic-based leachables that can originate from polypropylene vials Designed to hold up to 0.5 mL of unfiltered sample that can then be loaded directly into an autosampler Easy to see when a sample has been filtered Wide range of membranes with 0.2 and 0.45 µm pore sizes to meet specific requirements Also available in amber glass for light-sensitive samples Also available, the Whatman Mini-UniPrep in polypropeline format, designed for autosamplers. Process samples in one-third the time Mini-UniPrep Syringeless Filters combine a membrane filter, autosampler vial, septum, and plunger into a single device to provide efficient sample filtration for Ultra High Performance Liquid Chromatography (UHPLC)/High Performance Liquid Chromatography (HPLC) analysis. Mini-UniPrep G2 autosampler vials Once compressed, Mini-Uniprep G2 can be placed into any autosampler that accepts a 12 mm × 32 autosampler vial for injection into your instrument. Alternatively, the septum can be pierced with a needle and the sample drawn off for manual injection into an analyzer. Simplifying UHPLC/HPLC sample preparation minimizes instrument downtime resulting from use of unfiltered samples. Minimizes leachables Excessive leachables contamination from plastic vials can destabilize organic formulations and skew results. Mini-UniPrep G2 from Cytiva business features a borosilicate glass chamber, so sample contact with plastic leachables is minimized.
