24 Well 10 mL UNIFILTER microplate
The 10 mL 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 10 mL UNIFILTER microplate enables chemical and heat-resistant operation. The long drip directors facilitate collection of filtrate with no crosstalk.

384 Well 100 µL UNIFILTER microplate
The 100 µL UNIFILTER is the only 384 well filter microplate with a 100 µL well volume to allow a large enough sample for recovery after filtration. Beneath the filter plate are long drip directors designed to eliminate well to well contamination during the filtration process. 

The 384 well filter plate has been successfully used for DNA template cleanup, cell capture, and for the removal of unwanted debris.

96 Well 2 mL UNIFILTER microplate
The 2 mL UNIFILTER microplate is widely used for applications that require larger 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 2 mL UNIFILTER microplate enables chemical and heat-resistant operation. The long drip directors facilitate collection of filtrate with no crosstalk.

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