what’s new

Stable-labelled internal standards of antifungal agents Cerilliant has introduced five stable-labelled internal standards of the antifungal agents fluconazole, itraconazole, ketoconazole, posaconazole and voriconazole at 1 mg/mL concentrations.

Scientific and vacuum applications for DC motors are varied, an example being the Watt balance — a machine developed to compare masses with electrical values in a vacuum. The balance seeks to use Planck’s constant to redefine the kilogram in terms of voltage and current. The vacuum-capable motor has allowed scientists to build a 3-axis robot, providing the necessary mass movements for the experiment. maxon motor Australia Pty Ltd www.maxonmotor.com.au
