Online pH Monitoring in up to 96 Cell Culture Tubes

ITR iTube96Reader

The ITR iTube96Reader is a 96-channel transmitter for non-invasive pH monitoring in a multitude of samples. It is used with iTubes – plastic cultivation tubes with integrated optical pH sensors – which are ready-to-use. The reader fits into most standard shakers and has wireless connection to a PC. A light rack eases loading the reader and guarantees correct positioning of the iTubes on top. The ITR is ideally suited to optimize media composition, find feeding points and to improve harvesting strategies. The simultaneous pH monitoring in a multitude of cultivation tubes eases the work load in bioprocess development considerably.
