Contactless and non-invasive measurement of total cell density in your bioreactor with OPTURASPY.


We are excited to announce the newest family member of the ABER Instruments probe family, the OPTURASPY.

Measuring biomass inside your bioreactor has never been easier! Stick the SPY sensor of the OPTURASPY to your bioreactor surface and start monitoring your cell density in real-time. The sensor can be used for most transparent surfaces, from benchtop models to bioreactors at scale.

The OPTURASPY is a bio-reflectance sensor, which emits near-infrared light from the sensor into the medium of the bioreactor. Cells in the medium will reflect the light, which is then returned to the sensor. The intensity of the reflected light directly correlates with the overall cell density. This measurement can be conveniently adjusted to match any familiar offline reading.

Key features include:

  • Bubble filter algorithm removed background signals
  • Monitor biomass online and real-time
  • Accurate and precise readings
  • Wide linear range allowing use from seeding to harvest
