The rocking shaker is a microprocessor controlled instrument for precise rocking control. The operation may be continuous or timed, with the integrated electronic timer ensuring accurate repeatability of time-sensitive incubations. Speed and time setting are straightforward in the LED display. The load weight, up to 8 kg is its outstanding feature. An audible signal accompanies automatic switch-off to indicate the completion of a set time period. The interchangeable / stacking platform and accessories enable a wide choice of vessels to be used, including bottles, flasks and beakers, dishes, boxes and petri-dishes.
