PH Meter

The RI pH Meter provides accurate, real-time analysis of media pH within all incubators using its unique custom IVF pH probe. Measuring the pH of culture media accurately is extremely difficult because the pH of media droplets under oil shifts above 7.4 within just 2mins 30 seconds of removal from the incubator.

• All new data logging software with auto-archiving of measurements
• Culture dish probe design
• Excellent calibration response and repeatability
• Robust probe design
• 24 hour drift stability
• Compatible with all common incubators including Minc

Why use the RI pH Meter?

Measuring the pH of culture media accurately is extremely difficult because the pH of media droplets under oil shifts above 7.4 within just 2mins 30 seconds of removal from the incubator. So the likelihood is, if measuring the pH of media outside of the incubator, that you are measuring artefact pH Levels.
The RI pH Meter provides accurate, real-time analysis of media pH within the incubator using its unique custom IVF pH probe. The probe fits into all incubators and allows embryologists to adjust the CO2 concentration to obtain the correct pH in the media. No more guesswork or assumptions when trying to deliver the correct pH for the media being used.

State-of-the-art image quality

A media droplet is made up in the pH probe well and placed in the incubator. The thin ribbon cable can be passed out through a sample port or through the incubator door. The pH meter will then measure the pH in real-time displaying the value on the digital readout.

The probe has a semiconductor sensor at the tip. The probe is placed in the Petri dish shaped holder. This holder has a well where the media sample is placed. The probe contains a reference electrode that measures the temperature of the sample and compensates the pH reading accordingly.

As an optional extra the meter can have on board memory for datalogging. Test results stored by the pH meter may be easily downloaded to a personal computer for analysis and printing. With the new auto archiving feature, the software is very easy to use.
