Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis. AA measures

Whether you are looking for an HPLC or a GC, Buck can design a custom system for your application that will be easy to use, and give you maximum ROI through low cost of ownership. Our Gas Chromatographs can accomdate 6 Detectors from a choice of 9 an

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.

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

Although particle sizing is a mature technology, methods based on ultrasound and light scattering have been evolving slowly toward the characterization of ever-smaller particles, well into the nanometer size domain. Scanning electron microscopy (SEM)

Raman spectroscopy has undergone a revolution during the last seven to 10 years, largely as a result of massive investment in the telecommunications industry. What were previously very large benchtop instruments requiring a Ph.D. operator, liquid nit

Despite the technique’s maturity, ultraviolet and visible (UV-Vis) spectroscopy has been a fertile area for innovation. The continuous xenon light source, which operates from UV to near-infrared, has been an enabling technology for UVVis, says

Analytical balances, which are accurate to at least 0.0001 g or 0.1 mg, represent the highest precision weighing standard for general use. Analytical balances also excel at quantifying changes in mass. Software built into balances is a huge time-

Despite their maturity as a product category, chillers and baths continue their slow evolution, particularly in terms of controls and user interface. Cole-Parmer (Vernon Hills, IL) and other vendors provide units with a temperature stability of 0

Choice of clean room casework, or furniture, is one of the most important decisions made when setting up classified space. Cabinets and associated doors, hinges, handles, panels, benchtops, shelving, and vertical/horizontal surfaces must be compatibl

A clarification to our readers regarding an entry in the "Cleanroom Products" section of our November Product Resource Guide 2012.

“Informatics convergence” has become a buzzword among ELN vendors and their customers. According to Steven Eaton, marketing manager for chemical analysis and informatics at Waters Corporation (Milford, MA), convergence encompasses an info

For decades, rotary evaporators have 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 re

Fume hoods are notorious for consuming expensive resources, particularly electricity and conditioned air that is vented to the environment along with volatile chemicals and other toxins.

Microwave digestion is the preparation method of choice for analyzing metals in complex mixtures. Food and environmental industries favor this technique, which is also applicable to testing materials, soil, agricultural waste products, engine oils, a

Milling and grinding are ancient techniques that are working their way into high-tech markets. Kyle James, VP of sales at Retsch USA (Newtown, PA) notes that demand for particle size reduction systems has grown significantly from “alternati

Most laboratory workers view ovens almost as utilities, using them principally for drying glassware and heat-resistant equipment, regenerating desiccants and catalysts, gently heating samples, and curing or preparing materials and composites.

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

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.

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.

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

Laboratory water purification systems get no respect. They’re used every day, but few lab workers realize— beyond opening the spigot— how they operate. “The level of knowledge in the average lab about lab water is not very

BioTek’s new Epoch Multi-Volume Spectrophotometer System combines two innovative products into system designed for a wide range of applications, from nucleic acid and protein quantification on a micro scale to cell-based assays in microplates,

Introduction It has been known for several years that chemicals (e.g., BPA and phlalates) can leach out of the plastic, such as toys and baby bottles. The impact of these chemicals on human health is well known. Recent scientific reports have now
