The 800 µl Unifilter is the microplate most typically used in purifications, isolations, and separations of biomolecules, particularly DNA. The microplate has a well volume of 800 µl, which is excellent for standard DNA plasmid miniprep chemistries. The choice of short or long drip directors is application specific. The Unifilter 800 µl is constructed from rigid high grade polystyrene.
