pH Online

pH is one of the most critical parameters regarding the performance of culture media. The embryo´s internal pH which is known to regulate various metabolic and transport processes can only be maintained in an appropriate environment. Typically, checking media pH by conventional pH meters is too cumbersome and time-consuming to be done in regular intervals.

pH Online^TM is able to continuously monitor media pH in a reference dish placed in the incubator. Measurement is based on a non-contact, internally referenced dual luminophore technology which has huge advantages over conventional pH electrodes.

Second generation pH Online^TM is operated via the OCTAX Log & Guard^TM (Link) controller providing a sophisticated and extremely user-friendly software environment. New features comprise pH measurement and logging independent from a PC, web interface based data access, various alarming options and single point calibration.
