Whatman™ Mini-UniPrep™ G2 syringeless filters

Mini-UniPrep™ G2 is an all-in-one syringeless filter with a borosilicate glass chamber. It replaces syringe filters for autosampler-supported UHPLC/HPLC sample preparation with easier handling and fewer consumable components. Transform your HPLC and UHPLC sample preparation with our Mini-UniPrep™ G2 syringeless filters. These filters combine four steps into one to offer a fast, efficient, and less wasteful solution to sample filtration prior to chromatography.

• Features an integrated autosampler vial, plunger with attached filter membrane, septum, and 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

How the Mini-UniPrep™ syringeless filter works

Mini-UniPrep™ G2 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™ G2 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.
