Whatman 7720-7236 Microplate, 96 Well, 2000 microliter Volume, Glass Polypropylene, Fast Flow Filter Media, 1/pk

The 2 ml UNIFILTER microplate is widely used for applications that require larger sample or reagent volumes. Typically these applications include biomolecule purification by solid phase extraction and organic synthesis in combinatorial chemistry library generation.

• No cross talk. Patented integral filter design prevents well-to-well cross contamination.
• Economical to use. Wide range of well volume options ensures efficient use of materials.
• Better control. Choice of filter media allows control of the flow rates and retention characteristics.
• Versatile: A broad range of filtration media is available, including glass fiber, polypropylene, cellulose nitrate, cellulose acetate, nylon, and ion exchange cellulose.

The glass-filled polypropylene construction of the 2 ml UNIFILTER microplate permits chemical- and heat-resistant operation. The long drip directors facilitate collection of filtrate with no cross talk.

Two filter media for the 2 ml chemically resistant filter plate are PKP and GF/D. Both are chemically resistant with the PKP used for retaining solvent, while the GF/D is used for fast flow rates.

Proprietary Whatman UNIFILTER microplates with filter bottom wells are convenient and ready to use. Available in 24-, 96-, and 384-well formats, UNIFILTER microplates offer a choice of filter media to meet exact application requirements.

The novel drip director design of Whatman UNIFILTER microplates ensures precise collection of the filtrate to allow for further processing and analysis. UNIFILTER microplates are available in a range of well volumes from 100 μl to 10 ml.

The Protein Precipitation UNIFILTER FF (Fast Flow) microplate is optimized for removing acetonitrile-precipitated proteins from plasma or serum samples. This 2 ml, 96-well, rigid glass-filled polypropylene microplate is both robust and chemically resistant. The plate contains specially formulated dual membranes with two distinct layers. The top layer acts as a prefilter to remove coarse particulates. The bottom layer is oleophobic for retaining the well contents without dripping. This provides a final filter for removing fine particulate matter when a vacuum is applied.
