The ReactoMate DATUM is a dual-rod stainless steel and aluminum support system built to ensure the stability and safety of your lab reactor. The ReactoMate DATUM support system can accommodate a wide range of reaction vessels from 100 mL up to 5000 mL. Designed by chemists for chemists, low-friction polymer bearings line both the overhead stirrer alignment chuck and the neck support. Each DATUM system is also supplied with a molded drip tray that fits within the base of the support, for catching any drips and spills from the reaction vessel during draining.
