The unique 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 well volumes of 100 and 800µL, and 10mL.

Features and Benefits

  • No crosstalk. 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

24-Well 10mL UNIFILTER microplate

The 10mL UNIFILTER microplate is widely used for applications that require very large sample or reagent volumes. Typically these applications include biomolecules purification by solid phase extraction and organic synthesis in combinatorial chemistry library generation. The glass-filled polypropylene construction of the 10mL UNIFILTER microplate enables chemical and heat-resistant operation. The long drip directors facilitate collection of filtrate with no crosstalk.
