The technology behind visible light microscopes, the oldest true laboratory instruments, has not changed much in fundamental operation in 200 years.

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.  

Integration is the main reason for the virtual disappearance of the specialist GC or MS supplier that produces chromatographs for someone else’s mass detector, and vice versa.

One of the primary safety devices in laboratories where chemicals are used is the laboratory fume hood.

The use of freeze dryers extends from applications in academic labs to zoos. Moreover, this technology contributes to basic research and manufacturing.

HPLC is, for many scientists, an essential apparatus for the separation, identification, purification and quantification of various compounds.

In HPLC columns, reverse-phase and normal-phase chromatography separation methods are based on polarity. Reverse phase columns separate analytes based on their hydrophobicity, with the more hydrophobic compounds being retained longer on the column.

As a mature market, filtration moves forward incrementally through improvements in filter media and housings. 

Chromatographers who learned their craft 20 years ago may not have been familiar with autosamplers then, but today nearly every high performance liquid chromatography (HPLC) instrument includes an autosampler as standard equipment.

Cell culture incubators, also known as carbon dioxide (CO2) incubators, are by far the largest group in terms of sales and applications. CO2 incubators support cell culture work in basic research and in the biotechnology industry where CO2 is used

Centrifuges separate particles and structures suspended in liquid by applying thousands of gravitational force equivalents to the sample through spinning. Laboratories use centrifuges to clarify suspensions, separate liquids, isolate suspended particles, perform density measurements and for many other applications.

Biological safety cabinets (BSCs) are enclosures that protect users and the environment from biohazards by removing particulates and aerosolized pathogens from the work area through HEPA filtration, then recirculate or exhaust the purified air, hence, cleansing the workspace air.
