kLa values are based on measurements with PreSens’ SFS v4 plastic shake flasks at 50 mm shaking diameter and PBS buffer in the temperature range 30°C - 37°C. kLa for other diameters can be estimated according to kLa (other) = kLa (50 mm) x (d (other) / 50 mm)0.33.
Please note, that kLa values can only be calculated in a range from 60 to 250 rpm!
Results are estimates only. For precise measurements you can determine kLa values in your conditions. Please see our sensor knowledge page on methods to determine kLa, contact our service team for further information or consult the SFR vario manual.
