Mini UniPrep Syringeless Filter, Slit Septa 0.2µm Polypropylene 100/pk (WH/US203NPEPP)
Cytiva’s Whatman Mini-UniPrep Syringeless Filters provides efficient and cost-effective sample preparation for HPLC and other applications.
Cytiva’s Whatman Mini-UniPrep Syringeless Filters combine four products into one syringeless filter solution for efficient chromatography sample preparation for a broad range of applications. They are built for fast and easy high performance liquid chromatography/ultra high performance liquid chromatography sample preparation and analysis.
- All-in-one filtration device for quick and cost-effective chromatography sample processing
- Eliminates the need for separate syringes, syringe membrane filters, vials, and septa
- Designed for use with an UHPLC or HPLC autosampler for high-throughput analysis
- 0.2 µm and 0.45 µm filter pore sizes available to meet filtration sample requirements
- Housing options: amber to prevent photodegradation of light-sensitive samples, or translucent for easy visual inspection made from polypropylene (PP) material
A borosilicate glass vial version is available, Whatman Mini-UniPrep G2, eliminating plastic-based leachables that can originate from a polypropylene vial.
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.
