First introduced by Beckman in 1936, pH meters have become a mainstay of academic, industrial, and manufacturing laboratories. pH meters determine the acidity or alkalinity of a solution by measuring the concentration of hydrogen ions; H+; or, more a

Total organic carbon (TOC) analyzers are a mainstay in industries that must detect and quantify carbon content from many samples and sources. Unlike spectroscopy, which measures specific carbon species from their unique interactions with light, TOC a

Light microscopes, which view objects illuminated by visible light, have been around for centuries. Related are instruments that image nonvisible infrared or ultraviolet radiation, or ones that view fluorescence or Raman effects. All of these use opt

Oil-free diaphragm pumps have earned a reputation for environmental- friendliness for low- to medium-pressure applications. At the low-pressure end, pumps do not continuously send water down the drain as do aspirators and there is no contaminated oil

Time-of-flight (TOF) mass spectrometry (MS) works by imparting equal energies to all fragments. Since smaller particles thereby travel faster, their masses are determined by how quickly they travel from the source to the detector.

Whether to employ central washing stations or point-of-use washers located under a lab bench is something that has to be addressed with regards to laboratory glassware washers. The former provide an economy of scale and are popular with lab workers w
