Spectroscopy can cover a range of wavelengths, and this article focuses on the ultraviolet (UV) and visible (Vis) spectra, with a bit of near-infrared (NIR) too. These ranges allow for many applications as well as a variety of technologies.
Scientists developed vacuum pumps—and their cousins—centuries ago. Until relatively recently, though, the instruments didn’t include many controls.
Although the electronic laboratory notebook (ELN) market is mature, it has undergone several cycles during the past three decades. This existential back-and-forth has centered on whether ELNs should primarily serve as direct replacements for paper notebooks or something more.
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.
If the voluminous patent filings for new compressors, refrigerants, insulation, and power management are any indication, refrigeration technology is one of the most-researched engineering topics affecting lab operations.
This month, we highlight companies that will be exhibiting at two upcoming scientific trade shows–the American Association of Pharmaceutical Scientists’ Annual Meeting and Exposition (AAPS 2014) and the Society for Neuroscience’s Annual Meeting (Neuroscience 2014). AAPS 2014 takes place at the San Diego Convention Center from November 2-6 and offers pharmaceutical scientists the opportunity to network with others in their field and check out the latest pharma equipment. Neuroscience 2014 will run November 15-19 in Washington, DC, allowing neuroscientists to present emerging science, learn from experts, forge collaborations with peers, explore new tools and technologies, and advance careers.
Problem: The assessment of cell concentration and viability is an important step in the characterization of cell health. This information can be used for monitoring proliferation rates, optimizing growth conditions and normalizing cell data for further studies, such as assessing the impacts of cytotoxic compounds.
Current methods rely on multiple, sometimes complex, instrument platforms to provide these answers, reducing flexibility and increasing research costs. Other, simpler methods provide inconsistent results due to their dependence on single-uptake dyes, which do not effectively discriminate between the various states of cell demise. As a result, there is a crucial need for analytical methods that efficiently provide reproducible count and viability data.
