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.

Modern titrators can be simply classified as one of two types: potentiometric and Karl Fischer, with the latter available in both coulometric and volumetric versions. While titration may be considered a basic analytical method, modern titrators are far from simplistic. Many titrators offer a variety of automation options and can perform titrations with great accuracy with minimal operator intervention. According to this year’s survey results, over 82% of survey respondents use automated titration in their labs, with fully half of respondents also using an autosampler.

Microplate readers are commonly used in biological research for assay development (39.4%), measurement of biomolecule concentration (34.5%), cell biology (25%), biomarker research (24.0%), and DNA quantification (20% of survey respondents). In addition, microplate readers find use in disease study, IVF, proteomics, PCR setup, and stem cell research. With multiple read modes available and numerous accessories, choosing a microplate reader that meets your current and future needs can prove a daunting task.

Laboratory ovens are common instruments in most laboratories and are used across most scientific disciplines. Lab ovens are most commonly less than 12 cu.ft. in volume, although a great variety of sizes are available in benchtop, stackable, and floor-standing models. Over 25% of survey respondents reported using larger ovens in their labs. While lab ovens are most commonly used for heating and drying (75.6% of respondents), they find a variety of other uses including temperature-linked experimentation (41.7%), evaporating (37.0%), baking (16.5%) and sterilization (11.8%).

Freeze dryers find use in a variety of research and manufacturing environments and are commonly used for material storage, food and pharmaceutical processing, as well as for less common applications such as taxidermy and document recovery. With a wide variety of options available, there is much to consider when purchasing a new freeze dryer.

One of the primary safety devices in laboratories where chemicals are used is the laboratory fume hood. It allows a researcher to work with—but not be exposed to— materials that create toxic fumes or particles when it is properly installed and maintained.

A Laboratory Information Management System (LIMS) serves as the interface to a laboratory’s data, instruments, analyses, and reports. For many analytical laboratories, a LIMS is an important investment that assists management in evaluating the efficiency of the laboratory’s operations and reducing costs.

When it comes to common technology in a laboratory, centrifuges rise toward the top of the list. Centrifuges separate particles and structures suspended in liquid by applying thousands of gravitational force equivalents to the sample through spinning and play a role in a wide range of workflows and applications.

Microplate handlers are specialized robotic devices that transfer microtiter plates in three dimensional space from one location within a workflow to another. The “locations” are actually operations such as solvent addition (through liquid handling), aspiration, heating, shaking, incubation, washing, reading, and storage.

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.
Achieving water of a high quality requires the careful use of purification technologies and a method for accurately measuring and monitoring contaminants.

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 recycling, extractions, and separation of solvent mixtures.

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.

The wide variety of lab-shaker designs on the market reflects the increasing diversity of scientific experimentation. Labs now use a greater range of sample sizes than ever before, from liters to microliters. And while replicate and combinatorial studies increase the number of samples, requirements for environmental control create yet a third dimension that shaker designers must consider.
