Whatman filters are world-renowned as a standard for laboratory filtration and are associated with quality, reliability, and reproducibility. Products such as our ready-to-use glass fiber filters, for determination of suspended solids in water, or our Mini-UniPrep G2 filter vial, for preparing multiple HPLC/UHPLC samples simultaneously, help
Use the same material for mobile phase filtration and sample filtration to: • Reduce variation of analysis • Reduce rate of column clogging • Enhance lifetime of column If inline degassing is required, consider the Whatman Inline filter/de-gasser. Choose from two membrane options: • Nylon - when mobile phase is > 20% aqueous

The Whatman Mini-UniPrep G2 is an all in one device that functions both as a filter and a glass autosampler vial for sample preparation prior to UHPLC/HPLC. Liquid stored in glass, reducing leaching (specially with organic solvents) Works well for aqueous based samples; Sample only contacts plastic during the actual act of compression
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
1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.
Pore Sizes and Pore Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are usually for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm
