systems for real time OD acquisition on shaking incubators: get the most out of your cultivations
​
Real-time biomass monitoring is a valuable tool with diverse applications. It enables rapid strain screening, determination of minimal inhibitory concentrations for antimicrobial susceptibility testing, optimizing media composition for enhanced productivity in bioprocesses, monitoring cell growth in tissue engineering, assessing microbial activity in environmental studies and more. By providing real-time data on biomass levels, this approach facilitates quick decision-making, improves experimental throughput and reproducibility, as well as enhances overall efficiency across various scientific disciplines.

​Essi.tech is pioneering online biomass monitoring based on transmitted light detection, but our range of applications is extended with systems based on scattered light detection.
our technologies
accuRead
transmitted light detection
scatterRead
scattered light detection
The light source and detector are facing each other. Biomass prevents the light from travelling through it; the higher the biomass, the lower the optical readout.
The light source and detector are next to each other. Biomass scatters light in all directions and some of it is bounced onto the light detector; higher biomass titers casue more light to be detected.
accuRead
transmitted light detection
The transmitted light detection principle of the accuRead technology is similar to spectrophotometers with two additions:
-
the detection principle is adapted to work online during the shaking operation
-
the dynamic LED power adaptation reassures readouts also in high biomass ranges
Because of this it is possible to measure a large range of biomass titers (ODs) during the shaking operation with the acquired data directly comparable to offline spectrophotometric measurements.
scatterRead
scattered light detection
The transmitted light detection principle of the scatterRead technology features an accelerometer to determine the optimal timeslot to take a measurement. Although the acquired data is not directly comparable to offline measurements with spectrophotometers, it is exceptionally simple to integrate and works with a large range of vessels.
comparison of technologies
*Occasional discrepancies between spectrophotometers as well as accuRead sensors are possible.
​OD dock software powers most of our biomass monitoring systems. It is easy to use, enables seamless parallelization and reliably acquires data that is easy to handle.
