Filters

Laboratory filtration spans a broad range of applications from gravimetric analysis and particle collection through vacuum filtration of bulk reagents, in-line system protection, and analytical sample preparation. Filter selection requires matching membrane or paper composition, pore size, and chemical compatibility to the specific matrix, solvent system, and downstream analytical method in use. Quantitative ashless filter papers retain fine precipitates for gravimetric work without contributing residue to the final measurement, membrane filters provide precise pore size cutoffs for particle sizing and microbiological applications, and in-line filters protect HPLC systems and analytical instruments from particulate contamination that would otherwise accumulate in frits, injector ports, and flow cells over time.

Ibis Scientific supplies laboratory filters including qualitative and quantitative filter papers, membrane filters in a range of pore sizes and materials, in-line HPLC filters, and vacuum filtration assemblies suited to gravimetric analysis, sample preparation, microbiological testing, and general laboratory filtration applications.
