The ID Sensor pH is 7mm in diameter which makes it a compact solution to meet the needs of the tiniest of cell cultures. ID·Sensor pH enables real-time measurements in multi-well culture plates, microfluidics devices, tissue culture flasks, shake flasks, and bioreactors. Biocompatible, sterilizable, and non-invasive, ID·Sensors provide data exactly where the cells are, at the pericellular level, so you can be confident about the pH and DO levels your cells are experiencing.

Traditionally the pH of small-scale cultures has been difficult to monitor. The challenge of accurately monitoring environmental conditions as well as controlling process parameters was difficult to address. SBI's optical pH sensor effectively addresses this issue. When compared to standard electrochemical probes, this sensor's measurements had a 99.7% correlation with standard instruments. The optical pH sensor's performance was also compared in regular (320 mOsm/kg) and high-osmolality (450 mOsm/kg) cell culture media to simulate the increase in osmolality in pH-controlled cultures. Over a pH range of 6.38-7.98, the average difference between pH readings of SBI's optical sensor and the standard electrochemical probe was 0.04 pH units.
