Growth Profiler 960 • Generates growth curves of up to 960 microbial cultures (10 MTPs) in microtiter plates • Because oxygen-transfer rates of 40 mmol/L. h are readily reached (at 225 rpm/50mm), exponential growth (no O2-limitation) occurs up till OD600 values of 3 -10 (depending on the strain and its specific oxygen demand), which allows an accurate determination of maximal growth rates (see example curves at the bottom of this page) • Shaker unit can be set to slow down (e.g. every 30 minutes) to 30 rpm for a few seconds: in these few seconds the culture comes temporarily to a rest (surface becomes close to horizontal), and the 10 cameras make photos of the bottom of the (transparent) wells. • Image analysis software (included) quantifies the cell density, and produces growth curves for all 960 strains (see example growth curves at the bottom of this page; in this case, the biomass levels are expressed in OD600 equivalents) • Biomass concentrations can be quantified up to 20 g dry wt / L (corresponding to approx OD600 = 60) using a previously prepared calibration curve) when grey or black-walled MTPs are used • Biomass levels down to OD600 values of 0.05 or 0.1 (below 0.05 g dry wt/L) can be measured (see example growth curves at the bottom of this page) when white-walled MTPs are used. • Compatible with our standard microtiter plates and sandwich covers (that prevent cross-contamination and excessive evaporation) • Clamp system identical to the system used for our universal clamps • Incubator with heater allows temperature control between 20 and 40 degrees Celsius. • Suitable for bacterial and cell cultures • Until now only supplied to selected customers/collaborators, but available from stock to everyone soon (May 2016)
