Many scientists separate solutions with high-performance liquid chromatography (HPLC). “With this technology and others, users need data faster,” says Michael Frank, PhD, analytical HPLC marketing manager at Agilent (Santa Clara, CA). Other factors must also be considered. Ade Kujore, marketing specialist at Cecil Instruments (Cambridge, UK), says, “Users require HPLC systems that are fast, sensitive, stable, and easy to operate, with wide dynamic ranges.” She adds, “The ability to efficiently perform robust method development and to produce consistently reliable, inter-laboratory data are also requirements of HPLC systems.”
Universities are fuming over the money that hoods suck out of their systems. There’s good reason to get upset—research indicates that a traditional fume hood can use as much energy as a house, and some studies say as much as a few houses. Consequently, many universities run contests to reduce the energy consumption of fume hoods. Best of all, several advances in fume hoods can dramatically raise their efficiency.
Turning a sample into a suspension— the essence of homogenizing—occurs in a wide range of laboratory applications. In life science and clinical research, scientists often homogenize tissue samples for various analytical studies. One of
In the mid-1930s, Arnold Beckman created one of the first commercial pH meters— made originally to measure the acidity of lemons. Then an assistant professor of chemistry at the California Institute of Technology, he started selling his device
