The mission of the Institute for Health and Consumer Protection (IHCP) of the European Commission Joint Research Centre is to provide scientific and technical support to the EU policies for the protection of the interests and health of European citizens in the areas of food, consumer products, chemicals and public health. The Systems Toxicology Unit as part of IHCP is launching a call for tender for the purchase of a High Throughput Multiprobe Sonicator for nanomaterial dispersion and compound solubilisation in liquid media. The sonicator will be integrated into the existing robotic platform Hamilton of the High Throughput Screening facility, and will also have the possibility to serve as a standalone device. The sonicator shall allow the parallel direct sonication in all wells of standard 96 and 384 (or custom formatted) well-plates.
