Mini-UniPrep G2 Syringeless Filters are all-in-one filters that replace syringe filters, and speed up and simplify UHPLC/HPLC sample preparation. Mini-UniPrep G2 Syringeless Filters provide a fast and easy way to remove particulates from samples being prepared for Ultra High Performance Liquid Chromatography (UHPLC) or High Performance Liquid Chromatography (HPLC) analysis. In fact, Mini-UniPrep G2 lets you prepare samples three times faster compared to the syringe filter method. Thanks to the design of this “next generation” product, the filtered sample is stored within an integral borosilicate glass vial, minimising the risk of leachables contaminating the sample. Standardizing UHPLC/HPLC sample preparation with Mini-UniPrep G2 ensures that every sample is filtered prior to analysis, and hence minimises instrument downtime due to unfiltered samples. The elimination of multiple consumables from the sample preparation process also provides immediate time and cost benefits. The Mini-UniPrep G2 glass chamber can hold up to 0.5mL of unfiltered sample, While the integral borosilicate glass vial within the plunger can hold up to 0.33mL of filtered sample. The plunger contains a filtration membrane at one end and a pre-attached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the integral glass vial. Air escapes through the vent hole until the locking ring is engaged, providing an air-tight seal. Once compressed, Mini-Uniprep G2 can be placed into any autosampler that accepts 12mm x 32mm vials for injection into your instrument. Alternatively, the septum can be pierced with a needle and the sample drawn off for manual injection into an analyser. Mini-UniPrep G2 can be used with either the hand compressor (single position) or with a multi compressor. The multi compressor can process up to eight samples at one time, further improving sample processing time. A range of Mini-UniPrep G2 filters is available to meet specific needs. For customers who need to filter light sensitive samples, there is Amber Mini-UniPrep. For customers using robotics to maximise throughput, we offer Slit Septa Mini-UniPrep G2.
Mini-UniPrep G2 consists of an integral borosilicate glass autosampler vial, plunger with attached filter membrane, and septum/cap.
Glass construction of Mini-UniPrep G2 minimises the risk of leachables contaminating the sample.
Designed to be loaded directly into the autosampler.
Visual indication that the sample has been filtered. Minimise instrument downtime due to unfiltered samples.
Wide range of membranes with 0.2 and 0.45μm pore sizes to meet specific sample filtration requirements.
