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 PP 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

A variety of filter membrane media are available to meet your needs. Browse the Whatman line to find the right filter and compressor for your application.

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.

Once compressed, Mini-UniPrep™ G2 can be placed into any autosampler that accepts a 12×32 mm 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 analyser.

Simplifying UHPLC/HPLC sample preparation minimises instrument downtime resulting from use of unfiltered samples. Excessive leachables contamination from plastic vials can destabilise organic formulations and skew results. Mini-UniPrep™ G2 from Cytiva's business features a borosilicate glass chamber, so sample contact with plastic leachables is minimised.

With hand compressor.
