The Mini-UniPrep hand compressor is a time reducing compressor for the Mini-UniPrep G2 syringeless filter, a fast and cost-effective syringeless filter that simplifies UHPLC and HPLC sample filtration.

  • Ergonomic hand compressor allows for sample preparation with increased hand comfort
  • Mini-UniPrep all-in-one syringeless filter prepares samples three times faster than standard syringe filter method
  • Mini-UniPrep glass or polypropylene vials support analyses such as pharmaceutical quality control (pharma QC) and water monitoring
  • Mini-UniPrep vials can be loaded directly into the autosampler

Whatman Mini-UniPrep syringeless filters are available with a variety of membrane types, pore sizes, and vial characteristics. Browse the Mini-UniPrep range to find the right filter for your application.

Streamline filtration with a hand or multi compressor

Mini-UniPrep syringeless filters can be filtered by applying thumb pressure to the cap and forcing the plunger into the vial. Alternatively, use of a hand compressor allows for pressure to be spread over the palm of the hand to reduce fatigue over multiple samples.

Mini-UniPrep syringeless filters

By combining a syringe filter, vial, cap, septum, and plunger into a single device, syringeless filters provide a fast and easy way to remove particles from samples being prepared for Ultra High Performance Liquid Chromatography (UHPLC) or High Performance Liquid Chromatography (HPLC) analysis.
