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.

As we wind up this year’s Salary & Employee Satisfaction Survey, it seems that little has changed for many
of our 1,199 survey respondents. 

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.

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

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.

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.
