The expanded features in today’s pH meters reflect the broad use of this technology. Researchers use pH meters in a wide range of research fields—including biological and chemical, agricultural and environmental, and more—and virtually all kinds of manufacturing.

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 recycling, extractions, and separation of solvent mixtures.

Freezers and refrigerators are an integral part of any laboratory that requires temperature controlled storage.

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.

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.

Pipettes can be found in almost every laboratory and, if you’re looking to buy one, there are many options— manual or electronic, single or multi-channel. Luckily, a few main considerations can help in deciding whether or not to buy the latest pipette technology.

Total Organic Carbon (TOC) analyzers are a mainstay of environmental and quality control chemistry. TOC, a crucial metric in many processes, may arise from a combination of living or dead organisms or chemical contamination. Its measurement can serve as a surrogate for more difficult measurements or a screen for further analysis.

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) and application/task-specific ELNs exist, each with their own fans.

Water is the most commonly used laboratory reagent; however, the importance of water quality is often overlooked. Because impurities can be a critical factor in many research experiments, water purity ranks high in importance. There are several types of impurities and contaminants in water such as particulates, organics, inorganics, microorganisms and pyrogens that can adversely affect results.

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.

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.

Automated liquid handling (ALH) systems span the range from semi-automated multichannel pipettors to room-sized systems. The industry is trending toward versatile, modular ALH systems—seemingly for every budget. Likewise, instrumentation, software, and methods have followed the trend toward greater user accessibility.

Whether to employ central washing stations or point-of-use washers located under a lab bench or in a corner 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 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.

Glove boxes go by many different names and are used for many purposes. However, their essential attribute is the ability to maintain a completely separate environment from ambient. Glove boxes are completely closed compartments ranging in size from a few cubic feet to several hundred cubic feet and differ from other safety enclosures in two significant respects: users can introduce articles into glove boxes and manipulate them inside through ports fitted with gloves, and glove boxes typically use a specialized atmosphere.
