Hudson Robotics’ Rapid_pH is an accurate and reliable workcell for high-speed pH measurement in microplates. Using a proprietary technique, the workcell provides simple, fast and accurate measurements of the pH of a large number of samples in microplates, without the delays and inaccuracies inherent in electrode-based measurements. This workcell can measure the pH of every well in a 96-well microplate in under 6 min, with 0.1 accuracy. This compares to several hours that a traditional pH probe would require to perform 96 separate readings.
