06 Feb 2024

Cytiva's Whatman Mini-UniPrep Syringeless Filters provide efficient and cost-effective sample preparation for HPLC and other applications.

These syringeless filters combine four products into one solution for efficient chromatography sample preparation across a broad range of applications. They are built for fast and easy high performance liquid chromatography sample preparation and analysis.

Features and Benefits

  • hand holding syringe filterAll-in-one filtration device for quick and cost-effective chromatography sample processing
  • Eliminates the need for separate syringes, syringe membrane filters, vials, and septa - significant reduction in waste.
  • Designed for use with an UHPLC or HPLC autosampler for high-throughput analysis
  • 0.2 µm and 0.45 µm filter pore sizes available to meet filtration sample requirements
  • Compatible with most major autosamplers
  • Amber option to prevent photo-degradation of light-sensitive samples, or translucent for easy visual inspection. Made from polypropylene (PP) material
The Whatman Mini-UniPrep G2, which is a borosilicate glass vial version is also available, eliminating plastic-based leachables that can originate from a polypropylene vial.

How the Mini-UniPrep Syringeless Filters Work?

Mini-UniPrep syringeless filters can be used either manually or with a multicompressor. The multicompressor allows for processing of multiple filtration samples, further reducing sample preparation time for chromatographic analysis.

Using the Mini-UniPrep syringeless filter is easy. If you are not using a multicompressor, simply place your sample in the Mini-UniPrep device, insert the plunger, and compress. Your sample is filtered rapidly and easily. The unique design allows the liquid sample to be forced into the reservoir of the plunger. Any excess air escapes though the vent hole, until the seal is engaged. The Mini-UniPrep syringeless filter can then be used in an autosampler.
