What is the lowest elution volume that can be used with QIAprecipitator Midi and Maxi Modules?
FAQ ID -307

The lowest elution volume that should be used for both the QIAprecipitator Midi and the Maxi Module provided in the HiSpeed Plasmid Kits is 500 ul. The official elution volume for both modules is 1 ml. If a higher DNA concentration is desired and a reduction in yield of up to 10% is acceptable, the elution volume can be reduced. Elution volumes smaller than 500 ul will lead to incomplete wetting of the QIAprecipitator membrane and further reduced DNA yields.
