Introduction to Non-Contact Flow Detection A non-contact flow meter utilizes ultrasonic technology to measure flow rate at critical points of various biotech processes. Ultrasonic technology enables non-contact detection of flow, independent of liquid composition (turbidity, charge, temperature etc.). ProA Flow ultrasonic flow sensors clamp on to the outside of flexible or rigid tubing, send ultrasonic […]

Dissolved CO2 in Bioprocess CO2 has many important roles in growth and maintenance of cell and bacteria cultures. CO2 acts as an additive product which affects a wide range of metabolic and critical process parameters. It is important to track dCO2 in your cultures for: Intracellular/Extracellular pH changes Glycosylation and Molecule Stability Lactate production Monitor […]

One of the primary technological advantages of Tornado Raman analyzers over conventional Raman devices is the significantly higher optical efficiency delivered by our HTVS™ platform (described in this prior blog post). With 10x to 30x more photons per second, Tornado systems provide superior spectral data for better precision and sensitivity for PAT measurements, as we […]
