Title : Filtration
Content : Whether you need to separate and concentrate proteins and other biomolecules or collect and remove contaminants from air or liquid samples prior to downstream analysis, our broad selection of syringe filters, membranes, filter holders, and tangential flow and centrifugal filtration devices ensures we have the right solution for your application. Our time-tested filtration products are proven in HPLC, mass spectrometry, protein preparation, testing lab, and pharma QC workflows. Our products span the full range of scalable consumables and equipment for research, process development, environmental, and commercial manufacturing applications.
Title : Filter Paper
Content : Used commonly in quantitative and qualitative analysis, filter papers must be closely matched to the application according to the physical characteristics of the filter paper. There are many sizes, materials, types, and grades of filter paper available for a variety of applications. Whatman® filter papers use only the highest quality raw materials for high reproducibility and high uniformity. Whatman® cellulose filter papers are manufactured from high-quality cotton liners that are treated to achieve an α-cellulose content >98%. A wide selection of Whatman® filter papers are available to suit numerous laboratory applications. Pre-pleated (folded) filter paper is also available for convenience.
Title : Filtration for Bioprocessing
Content : Buffer Filtration Clarification Filter Holders & Systems Filters for Food & Beverage Production Filter Housings /Final Sterile Filtration & Filling /Gas & Vent Filters /Integrity Testers /Media Filtration /Prefilters & Bioburden Control /Sterile Filters /Virus Filter Holders & Systems /Virus Filters
Title : Laboratory Filter Holders
Content : Filter housings are used in conjunction with cut disc membrane filters providing structural support and creating a seal around the membrane to prevent filtrate contamination. Reusable syringe filter holders are suited for filtering or clearing small amounts of liquid where a replaceable or removable filter is desired. Filter holders for vacuum and pressure filtration are available in a variety of formats and sizes to accommodate a range of filter diameters
Title : Vacuum Filters
Content : We provide bottle-top vacuum filtration and pressure filtration units for routine filtration of buffers, solvents and culture media, syringeless filters for HPLC and UHPLC sample preparation, pressure filter funnels for solute and compound drying, and analytical filter funnels for microbiological testing. Vacuum manifolds and in-line filter devices to help confine and isolate contaminants in vacuum systems are also available for convenience.
