Bio-reflectance Sensors

OPTURA SPY Bio-reflectance Sensors

At the speed of light

The ABER OPTURA SPY uses patented bio-reflectance technology to bring live biomass readings in real-time. The OPTURA SPY adheres to glass reactors, SU Bags, Assemblies, and SU vessels (Ambr®15 & 250, BioBLU®, Shake Flasks, etc.). The bio-reflectance sensor emits a single wavelength of NIR light into the medium. The light is then reflected by the cells and returns to the detector. The detected light intensity is directly proportional to total live cell density.


OPTURA bio-reflectance technology uses a patented bubble algorithm. This bubble filter allows the OPTURA technology to provide consistent live biomass readings across a range of gas flow rates.
