General description

The Whatman Mini-UniPrep G2 is an all in one device that functions both as a filter and a glass autosampler vial for sample preparation prior to UHPLC/HPLC.

  • Liquid stored in glass, reducing leaching (specially with organic solvents)
  • Works well for aqueous based samples
  • Sample only contacts plastic during the actual act of compression
  • Improved solvent evaporation rates
  • Process samples 3X faster than traditional syringe filter method
  • All-in-one device replaces multiple consumables
  • Reduce lab waste
  • Simplify ordering
  • Fewer consumables to store in lab
  • Designed to fit any autosampler that accommodate standard 12 x 32 mm vials

Features and Benefits

  • 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
