The Optek Turbidity Sensors (Optek-ASD series) are precision-engineered NIR absorption sensors designed to deliver real-time data on the growth of microorganisms and cell cultures. Mounted directly into a 12 mm or 25 mm vessel port, these sensors provide reliable optical density and turbidity measurements, ensuring optimal monitoring and control during bioprocessing and fermentation.

Perfect for scale-up and process optimization, Optek turbidity sensors allow researchers to track biomass concentration with exceptional accuracy. The system supports high-density microbial applications and low-density mammalian or plant cell cultures, making it a versatile solution for research laboratories and industrial bioreactors alike.

With robust stainless-steel construction, an optimized flow path, and full sterilization compatibility, the Optek-ASD ensures long-term durability and contamination-free operation. Comprehensive data logging and software integration make it easy to compare growth curves, document performance, and create automated feeding profiles based on live biomass readings.
