Microwell plates: For Plate Reader users, it is important to confirm with your plate manufacturer that your plates, lids, and covers are all DMSO-compatible.

Either discard the first few drops of filtrate or wash the filter with solvent in order to remove particulates from the dry filters. Filters and housings: While we encourage you to optimize your DMSO-compatible filtration system to suit your analyte(s)-we generally recommend Whatman™ polypropylene-based Anotop™ filters, which are adequate for filtering aqueous solvents containing 0-100% DMSO.To maintain clean glassware, rinse out your solvent reservoir with ultra-pure water followed by alcohol to aid in drying prior to filling with your filtered solvent that contains DMSO.Ģ.Ğnsure chemical compatibility with DMSO.Please heed the following best practices for minimizing DMSO-related particle contamination, as well as specific guidelines regarding safe handling of DMSO.ġ.Ělways work with fresh, filtered solvents in clean glassware, and transfer “working volumes” by pouring rather than directly pipetting. While relatively inert and non-toxic, DMSO is a hygroscopic solvent that dissolves a wide variety of different polar and non-polar molecules-this makes it very easy to contaminate your samples with unwanted particles.
