The wide spectrum of columns available makes selecting this most important component of an LC system extremely difficult. Column choices span normal phase, reverse phase, size exclusion, ion exchange, hydrophobic interaction, & affinity chromatography. One is hard-pressed to find a more innovative, self-reflective instrument market.

Thermal analysis is the broad category of at least 20 techniques that measure some fundamental property of matter as a result of adding heat. For example, dilatometry measures volume changes upon heating, thermomechanical analysis quantifies the change in dimension of a sample as a function of temperature, and thermo-optical analysis detects changes in optical properties on heating or cooling.

Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; they are visible from 4000 to 7000 angstroms.

Vacuum pumps are an essential piece of equipment and are used in a wide variety of processes in most laboratories. Over the past 25 years, it has become apparent that vendors have made significant innovative improvements to vacuum pumps, with important developments in high vacuum technology, corrosion resistance, vacuum control, and improvements in the efficiency and ecological impact of vacuum pumps.

Electronic laboratory notebooks (ELNs), one component of a lab’s information infrastructure, help laboratories capture and manage knowledge, streamline data management, protect intellectual property and foster collaboration. Both non-specific/generic ELNs (which compete directly against paper notebooks) & application/task-specific ELNs exist, each with their own fans.

CO2 incubators are designed to copy a cell’s natural environment with a relative humidity of around 95 percent, a temperature of 37°C and a pH of 7.2 to 7.5. They are most common in biology labs performing tissue or cell culture and are used in any process where cells need to be cultured for a few hours or many weeks or where cells need to be expanded or maintained.

Gas chromatography (GC) is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. GC is typically used for separating the different components of a mixture, improving the purity of a particular substance, or identifying a particular compound. GC is a ubiquitous technique, and the various GC instruments available are designed to achieve every requirement of the technique.

Common laboratory ovens maintain temperatures ranging from just above ambient to about 300°C and are ubiquitous in chemistry, biology, pharmaceutical, forensics, and environmental labs. Units operating at temperatures above 300°C are normally dedicated to specialized applications in physics, engineering, electronics, and materials processing. Typical lab ovens use four to six cubic feet of space and are located on benchtops or stacked atop another oven; other units may be much larger.

Whether to employ central washing stations or point-of-use washers located under a lab bench or in a corner is also 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 who, almost universally, hate to “wash the dishes.” The downside for central washing stations is that glassware tends to disappear over time, due to breakage and operator error.

High-performance liquid chromatography (HPLC) is, for many scientists, an essential chromatographic technique. HPLC systems used for the separation, identification, purification and quantification of various chemical and biochemical solutions are composed of a pump, a sample injector, a separation column, a detection unit, and a data-processor.
