Hydrodynamics inside wells of a 24-roundwell microplate
For 24-roundwell microtiter plates, culture volumes between 0.5  and 1 ml are used, mostly either at 300 rpm on a shaker with a 25 mm amplitude (video on the left) or at 225 rpm on a shaker with a 50 mm amplitude (video on the right).Under both conditions (at a culture volume of 0.75 ml), oxygen-transfer rates approximate 30 mmol O2 l-1 h-1  (corresponding to kLa values of 150 h-1).For the (slowed-down) high-speed videos below we used 24-well plates from Corning, which are widely used for the c*tion of bacteria and cells, also because they are worldwide available with various surface treatements (causing different binding characteristics) and gamma irradiated.
