ID Sensor

Intelligent, Dynamic pH and Dissolved Oxygen Sensors

Sensors so small that fit in even the smallest culture systems are redefining cell culture. The 5mm diameter ID·Sensor DO and 7mm diameter ID·Sensor pH enable 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.


How can I incorporate optical sensors in my custom cell / tissue / organ culture system?

The ID • Developer’s Kit is well-suited for a wide range of custom microbial and mammalian cell culture systems.

  • ID • Sensor pH and ID • Sensor DO can be as small as 4mm in diameter to fit even the smallest culture systems. Attach the sensor to the bottom inner surface of your culture vessel.
  • ID • Reader is placed below a flat glass or plastic surface within 1cm from the smallest sensor and can be further away for larger sensors. Sensor placement is parallel to ID • Reader.
  • ID • Data Hub software loaded onto your laptop collects data through the ID • Converter.
