What Is pH, And How Is It Measured?
By Frederick J. Kohlmann
Almost all processes containing water have a need for pH measurement. Most living things depend on a proper pH level to sustain life. All human beings and animals rely on internal mechanisms to maintain the pH level of their blood. The pH of wastewater leaving manufacturing plants and wastewater purification plants must be within a specific pH "window" as set forth by local, state, or federal regulatory agencies.


How To Choose The Right Connector
By Colder Products Company
With so many connection options, it can be difficult to determine which connector is best suited for a specific application. By understanding your application requirements and selecting the correct connection type, you can achieve better performance and sealing results.


Grignard Reactions Under Control With RTCal — Calorimetry In Real Time
By Mettler-Toledo International Inc.
Reducing development time, resources, and precious material consumption provides significant value for the pharmaceutical industry. Progress in material sciences and technology now enables sensors to be embedded into double-walled glass reactors to measure heat data in real time. RTCal allows adjustments to the actual chemistry and rapid optimization of critical reaction parameters online and in real time.
