Mini-UniPrep syringeless filters are available in a veritable alphabet soup of filtration media options: polypropylene (PP), polytetrafluoroethylene (PTFE), nylon (NYL), glass microfiber (GMF), polypropylene depth filter (Depth PP), polyvinylidene difluoride (PVDF), polyethersulfone (PES), and regenerated cellulose (RC).
Whatman Mini-UniPrep syringeless filtration for HPLC
Chromatography sample preparation steps involving multiple consumables like syringe filters, vials, and septa increases costs and time required for sample preparation. Whatman Mini-UniPrep syringeless filters eliminate the need for these separate disposable components and prepare samples in one-third the time required by other methods used for high performance liquid chromatography.
By excluding large particles from a chromatography sample, the time required to process the mobile phase is shortened. Also, HPLC column life is extended by reducing contamination that ultimately causes clogging and back pressure build up.
How the Mini-UniPrep syringeless filter works
Mini-UniPrep syringeless filters can be used either manually or with a multicompressor. The multicompressor allows for processing of multiple filtration samples, further reducing sample preparation time for chromatographic analysis.
Using the Mini-UniPrep syringeless filter is easy. If you are not using a multicompressor, simply place your sample in the Mini-UniPrep device, insert the plunger, and compress. Your sample is filtered rapidly and easily. The unique design allows the liquid sample to be forced into the reservoir of the plunger. Any excess air escapes though the vent hole until the seal is engaged. The Mini-UniPrep syringeless filter can then be used in an autosampler.
