| Sample Filtration with Whatman Mini-Uniprep filter system |
Overview
Whatman Mini Uniprep syringeless filters offer a convenient way of filtering samples containing particulates prior to introduction on an HPLC system. They come with 2 pore sizes and may different filter substrates [1]. They are designed for manual operation but are not conducive to high throughput - repeated pressing by hand being quite fatiguing.
LEAP has developed a "Press" accessory for the PAL which allows samples to be filtered reliably and repeatably. It does not require external pneumatics, but uses the PAL Z motion itself to compress the filter chambers. Samples can be processes in batch mode or "just in time" before direct injection to the LC valve.
