Mini-UniPrep™ G2 syringeless filter for UHPLC/HPLC sample preparation

Learn about the key components of the Mini-UniPrep G2 filter system: the borosilicate glass chamber, plunger with Whatman filter membrane, and glass collection vial. This streamlined device replaces four separate components for efficient HPLC/UHPLC sample preparation.

Place the glass chamber into the hand compressor base and fill it with sample liquid up to the indicated fill line. Insert the plunger into the chamber until it stands on its own.

Use the hand compressor to safely depress the plunger into the unfiltered liquid. The compressed force drives the liquid up through the filter membrane and into the glass collection vial while removing particulates.

Remove the filtered sample from the collection vial, which is now ready for analysis. The high purity borosilicate glass vial ensures sample integrity and the device can be loaded directly into an autosampler.

For high-throughput applications, use the multi-compressor to process up to eight Mini-UniPrep G2 samples at once. Insert collection chambers, fill with liquid, insert plungers, and depress the handle to filter multiple samples rapidly.

The Mini-UniPrep G2 is compatible with high-throughput robotic systems to further improve workflow and laboratory productivity. This integration ensures consistent filtration and eliminates instrument downtime from unfiltered samples.
