Mini-UniPrep G2 Syringeless Filters provide a fast and easy way to remove particulates from samples being prepared for Ultra High Performance Liquid Chromatography or High Performance Liquid Chromatography analysis. Simplifying UHPLC/HPLC sample preparation minimizes instrument downtime resulting from use of unfiltered samples.

The design of this next generation product eliminates many consumables from the process, providing immediate time, cost and process benefits: the plunger contains a filtration membrane and an attached cap/septum, while the integral glass autosampler vial eliminates leachables contamination (common with polypropylene vials) that can skew results. Mini-UniPrep G2 can be used with either the single position hand compressor (included) or with a multi compressor that can process up to eight samples at one time.

  • Features an integral borosilicate glass vial, plunger with attached filter membrane, and septum/cap
  • Borosilicate glass vials eliminate leachables that can contaminate the sample
  • Designed to be loaded directly into any autosampler that accepts a 12 x 32mm vials -OR-
    Septum can be pierced with a needle for manual injection into an analyzer
  • Vial holds up to 0.5mL of unfiltered sample or 0.33mL filtered sample
  • Clear vial allow visual inspection to easily confirm that the sample has been filtered
  • Amber glass vials protect light-sensitive samples from damaging UV exposure
  • Wide range of membranes with 0.2μm pore sizes to meet specific requirements
