| 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 |
| 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 |
