Aquila - Cell Growth Quantifier (CGQ)
The CGQ is a sensor-based technology that offers highly parallelized, non-invasive online monitoring of biomass in shake flasks and other cultivation vessels. Our patented sensors are easy to install under the vessel and monitor the biomass through the glass wall by backscatter measurements. This enables you to follow the growth of your cultures in real time and generate profound bioprocess understanding.

- Bacteria, archaea, fungi, yeast, algae, plant cells and more
Compatible with various cultivation vessels
- Shake flasks, serum bottles, Schott bottles and others
Works on all types of shakers
- Compatible with any shaker and clamps as well as sticky stuff
One sensor for all shake flask sizes
- Use one sensor for different shake flask sizes by applying our adapters
Highly parallelized measurements
- Monitor up to 64 shake flasks in parallel on one laptop
Easy to install and use
- A plug and play technology with an intuitive user interface
What does the CGQ measure?
Using an array of LEDs and photodiodes, each CGQ sensor plate can adaptively measure the backscatter intensity at different radial positions, thus accounting for a broad variety of liquid distributions in shake flask fermentations. Furthermore, the CGQ’s innovative measuring method treats the signal fluctuations as a valuable information source rather than noise.
How is scattered light used to measure biomass?
The CGQ implements the well-known technique of light scattering with light source and sensor mounted directly into the spring clamp under the shake flask. Depending on the current biomass concentration inside the flask, different amounts of light are scattered towards the sensor.
Has the CGQ technology been used in any published research?
