In-line sensor for measuring glucose and lactate concentrations
Based on YOKOGAWA's original calibration model and instrumentation, the concentration of glucose and lactic acid in the culture medium can be measured in real-time and with high accuracy based on the absorption characteristics of near-infrared light.
In-line sensor to measure live cell density
Based on YOKOGAWA's original calibration model, the live cell density can be measured in real time from changes in the capacitance characteristics of the cell suspension. The unique calibration model also maintains high accuracy throughout the entire cell culture timeline, from seeding to high cell densities.
Soft sensor for estimating glucose consumption rates in real time
A model prediction and control algorithm processes the data obtained by the in-line sensors and outputs a highly accurate glucose consumption rate trend in real time.
Advanced control to automatically control glucose concentration
An advanced control algorithm designed specifically for cell culture provides accurate and automatic control of glucose based on in-line sensor values. Peristaltic pump systems dynamically deliver sterile glucose solution as needed to maintain the glucose set-point concentration value.
Features of the system
The instrument provides basic control of pH, temperature, and dissolved oxygen, a near-infrared sensor for monitoring cell activity, a viable cell density sensor, feed control, and data logger, all integrated into one complete system.

A critical requirement in biopharmaceutical development is the integration and automation of process equipment and analytical instruments used in the laboratory. Bioprocess labs with multiple lab-scale bioreactors often execute cultivation experiments in parallel for research or process development purposes.
As part of a collaboration between Securecell (Zurich, SW) and Yokogawa Life Science (Tokyo, Japan), this application note demonstrates the effective use of the Lucullus® Process Information Management System (Lucullus®) to assist in the control of three Advanced Control Bioreactor Systems (BR1000) to study glucose utilization of CHO cells for optimal monoclonal antibody productivity.
This paper describes how the Yokogawa BR1000 bioreactor can be used to automate through real-time sensing and improve productivity through accurate and efficient glucose control.
Our approach is to leverage state-of-the-art technologies for real-time monitoring and predictive control that allow virtual environments where "digital twin" processes can provide distinct advantages.
