Read the fascinating results of Lab Manager's survey on UV-Vis spectrophotometers.

Oil-free diaphragm pumps have earned a reputation for environmental- friendliness for low- to medium- pressure applications. At the low-pressure end, pumps do not continuously send water down the drain as do aspirators.

Although serious Fourier-transform infrared spectroscopy (FTIR) research and core analysis facilities are still alive and well, traditional applications are giving way to more dynamic uses such as controlling processes and field work.

Despite their maturity as a product category, chillers and baths continue their slow evolution, particularly in the areas of controls and user interface.

Despite the technique’s maturity, ultraviolet and visible (UV-Vis) spectroscopy has been a fertile area for innovation, both in terms of underlying technology and instrumentation.

In many applications, contamination of the gas stream must be prevented. When processing gases or sampling elements within a controlled environment, conveying the gas desirably cannot add trace elements such as lubricants or wear particles.

The simplest lab vacuum applications require little or no control; vacuum filtration and aspiration require only the simple application of modest suction.

Must-have features of the SC 920 system are 2 mbar end vacuum, excellent flow at end vacuum, efficient solvent recovery, and automatic boiling point detection.
