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.

A fume hood is an essential piece of equipment found in almost all laboratories, from teaching labs to research labs to industrial labs.  Learn the history of this important part of the lab.

Ultra-high-throughput screening (uHTS) is an automated methodology for conducting hundreds of thousands of biological or chemical screening tests per day using liquid handling devices, sensitive detectors, robotics, data processing, and control software.

Liquid chromatography is an essential process in many laboratories for the separation, identification, purification and quantification of various compounds.When purchasing a liquid chromatography system, consider a more general purpose HPLC system.

This purchasing guide attempts to simplify the range of available particle characterization instruments by categorizing them according to type and function.

There are a number of standard laboratory procedures and processes that need to be conducted at specific and stable temperatures.

Most modern laboratories rely on some form of integrated Laboratory Information Management System (LIMS) to improve efficiency and productivity in the lab.

Mixing solutions is one of the most common laboratory tasks. Over the years, a number of automated methods for mixing have been devised, all of which remove this burden from the operator by offering a sustained and controlled stirring action for indefinite periods of time.

This purchasing guide presents models of benchtop elemental analyzers currently available for the laboratory.

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