EloCheck: Inline/Online measurement of optical densities
EloCheck is an automatic bypass-photometer for continuous analysis of cell suspensions and chemical solutions. Flexible polynomic functions allow the calibration to free definiable units like CFU/ml, g/l, NTU etc. EloCheck provides various ways of measuring, storing, viewing, comparing and exporting of optical data. A convenient comparison with previous fermentations grants a user-friendly control of reproducibility and optimal improvement of the yield quality.
The integrated high-end sensors and the optimized measuring cuvettes allow a real-time recording of optical densities of 70 and higher (OD10 mm) without any further pipetting or dilution steps.
