Compact Fiber Optic pH Meter
The pH-1 mini is a precise fiber optic pH meter. It is used with pH sensors based on a 2 mm optical fiber. A PC is connected to run the easy-to-use software and control measurements. pH-1 mini is equipped with an analogue out and a trigger input. pH sensors type HP5 & HP8 are compatible with the pH-1 mini and are optimized for physiological solutions.
- For use with non-invasive pH sensors, dipping probes & flow-through cells
- One calibration for a multitude of sensor spots
- Software included
Bioprocess Development: pH Monitoring in Shake Flasks
The pH is one of the major issues in the cultivation of cells, yeast or bacteria. Shake flask cultures are widely applied in academic and industrial bioprocess development. As adequate methods for real monitoring of pH were not available, cumbersome at-line sampling was used. The combination with non-invasive oxygen sensors in shake flasks provides new insights into metabolic activity and changes in metabolic pathways.
