Lab water, purified by any of a number of means, is a vital resource in most laboratories. Purified lab water ranges from Type I, which is suitable for analytical tests requiring minimal interference and maximum precision and accuracy, through Type II for analytical tests in which the presence of bacteria can be tolerated, to Type III, which is suitable for general washing and for use as feedwater for producing higher grade water, as well as bacteriological media preparation.

Indispensible equipment for laboratories, fume hoods and biological safety cabinets (BSCs) protect personnel from exposure to chemicals and pathogens handled during experiments.

Mass spectrometers, one of the principal instruments for investigating chemical composition, operate by separating ions according to their mass/charge ratio by transmitting them through a magnetic and electrical field.
