Overview

Transform your HPLC and UHPLC sample preparation with our Mini-UniPrep™ syringeless filters. These filters combine four steps into one to offer a fast, efficient, and environmentally friendly solution to sample filtration prior to chromatography.

Chromatography sample preparation steps traditionally involve multiple consumables like syringe filters, vials, and septa, which increases costs and time required for sample filtration. Mini-UniPrep™ syringeless filters eliminate the need for these separate disposable components and prepare samples in one-third the time required by other methods used for high performance liquid chromatography.

By excluding large particles from a chromatography sample, the time required to process the mobile phase is shortened and HPLC column life is extended by reducing contamination that causes clogging and back pressure build up.

  • Features an integrated autosampler vial, plunger with attached filter membrane, septum and cap: eliminates the need for separate syringes, syringe membrane filters, vials, and septa.
  • 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 sample filtration requirements.
  • Housing options: amber to prevent photodegradation of light-sensitive samples, or translucent for easy visual inspection made from polypropylene (PP) material.
