Online measurement with methods such as control of pH and dissolved oxygen are common for most biological processes. In fact, many parameters can be monitored but those directly related to cell physiology are time consuming offline measurements that only provide a reactionary window into the past. Incyte and Dencytee sensors provide a means for directly measuring viable and total cell density in real-time. Obtain advanced control with never-before instantly available data. With clear, up-to-date information, critical events that could have been missed between offline samples are now immediately recognizable. Automate production processes and strategize product development with new awareness in R&D.
