In flame photometry, a branch of atomic spectroscopy also called “flame atomic emission spectrometry,” atoms are examined in the spectrometer.

Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum.

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.

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.

Learn recent trends in Raman spectrophometers as well as some of the main questions you should ask before buying one.

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.

ELNs are not the hub for capturing every piece of laboratory data. There will always be a need for LIMS, SDMS and other informatics repositories that are specifically designed to handle structured or unstructured information. ELNs are, however,

Rotary evaporators have for decades been staples in labs and industries performing chemistry, including labs in the chemical, environmental, materials, life science and forensics industries. Key applications include sample concentration, solvent

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

Flow cytometry is a powerful technology that allows researchers and clinicians to perform complex cellular analysis quickly and efficiently by analyzing several parameters simultaneously.

A Laboratory Information Management System (LIMS) serves as the interface to a laboratory’s data, instruments, analyses and reports.

Low-temperature laboratory freezers will achieve temperatures of -40°C to -85°C, much lower than their kitchen-based counterparts.

Microwave digestion is the preparation method of choice for analyzing metals in complex mixtures.

In a laboratory, most materials required for sampling are, in practice, nonhomogeneous mixtures.

Nobody gets excited about lab ovens, but they are definitely essential lab components. Ovens are found in almost every industrial, research and development laboratory.

The expanded features in today’s pH meters reflect the broad use of this technology.

Best practices dictate that pipettes undergo preventive maintenance and calibration at least once per year. Calibration involves dispensing set volumes of a liquid, usually water, into the weighing pan of a calibrated balance.

Titrators are specialized instruments that perform titrations with minimal operator intervention and can thus minimize errors, improve throughput, and facilitate documentation.

A mainstay of environmental and quality control chemistry, TOC analyzers measure the carbon content of dissolved and particulate organic materials in water.

Vacuum pumps are an essential piece of equipment and are used in a wide variety of processes in most laboratories.

Viscometers measure viscosity, the resistance of fluids to flow or stress. In common terms, viscosity is related to a fluid’s “thickness”—a physical property of great interest to manufacturers of liquids, slurries, and pastes.

A successful water system design begins with a clear and precise definition of user needs throughout the facility.

Find out the main questions you should be asking when buying an automated liquid handling system.

Electrophoresis relies on a basic process—particles moving in an electric field, more or less. Although known for more than 200 years, this phenomenon still drives fundamental techniques in many laboratories.

Microplate handlers are specialized robotic devices that transfer microtiter plates in three-dimensional space from one location within a workflow to another.

Microplate readers are widely used in research, drug discovery, bioassay validation, QC, and manufacturing processes for the detection of biological, chemical, or physical processes in samples contained in microtiter plates.

Within a decade of its discovery in 1983, Real-Time PCR—also called quantitative polymerase chain reaction (qPCR)—evolved into one of the most powerful and sensitive gene analysis techniques available.

Reagent companies sell RNAi reagents as “virtual kits” consisting of the shRNA or siRNA sequences and an appropriate transfection reagent.

This year marks the 25th anniversary of commercial thermal cyclers for the polymerase chain reaction (PCR). In brief, this technology amplifies segments of DNA. In such a device, PCR tubes go in holes in a thermal block.
