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
Whatman filters are suitable for sample preparation in applications such as filter, a vial and a cap. Right: The Mini-UniPrep G2 multicompressor can filter up ... PES 0.2 Translucent Slit septum US203NPEPES US503NPEPES PES 0.2 Amber Standard UN203APEPES
General Info Technical Resources Request A Sample. Filter Vials are a single system which replaces HPLC Vials, HPLC Caps, Syringes, & Syringe Filters for the filtration of samples. In 15 seconds, Thomson Filter Vials allow for sample preparation of unfiltered samples to filtered samples in an autosampler-ready vial.

Recommended for samples containing less than 10% solid particulates. Easy-to-use vials offer fast sample filtration and require only a squeeze of your fingers. Minimize sample loss by eliminating multiple transfers. Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon.

Sample Preparation by Filtration. Filtration is a separation technique used to concentrate or purify substances based on their physical or chemical properties. It is a simple and routine method used in many laboratories to remove insoluble particles from solutions and to prepare samples for analysis. Filtration is used to reduce sample
