Description

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

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
