Syringeless filters, Mini-UniPrep™ G2, Whatman™

Supplier: Whatman (GE Healthcare)
Whatman™ Mini-UniPrep™
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 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 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 GE Healthcare’s Life Sciences business features a borosilicate glass chamber, so sample contact with plastic leachables is minimised.

* With hand compressor
