The pH of the culture medium is a critical process parameter in cell culture bioprocesses. To successfully transfer processes between bioprocess systems and sites (i.e., in the course of process ...

A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...

pH meters are used to determine the pH of a water sample or solution. There are four pH meters in the engineering laboratories. pH meters use electrodes to determine the difference in electrical ...

In coal-fired power plants, measurement and control of pH is critical to the efficient operation of wet flue gas scrubbers. However, harsh process conditions can necessitate frequent cleaning and ...

Methods for efficiently identifying subjects with constantly acidic pH in epidemiological and clinical studies have not been assessed. We recruited 30 volunteers to estimate the minimum number of ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

When Arnold Beckman, a professor of analytical chemistry at the California Institute of Technology, was asked to devise a way to measure acidity in citrus fruit, the resulting “acidometer” ...
