A laboratory device to automatically measure growth of cell culture non-invasively

The invention relates to a system for non-invasive and automatic real-time cells culture growth measurements. The system comprises a vessel for holding a liquid sample with cell culture, an optoelectronic circuit system, an electronic system, and a holder. The optoelectronic circuit system comprises a light source configured to emit light radiation onto the liquid sample being held by the vessel, and a photodetector configured to detect the light radiation after the sample has been exposed to the light radiation. The electronic system is configured to receive signals generated by the photodetector and determine the cell growth based on the signals. The holder includes the light source and photodetector of the optoelectronic circuit and is configured to receive and secure the vessel.
