Grant Instruments has introduced a heavy duty microprocessor controlled 3-in-1 multi-Functional orbital platform shaker, designed for use in biotech, biopharmaceutical and academic research laboratories. The latest addition to the Grant-bio product range, the PSU-20 platform shaker combines three mixing functions - orbital motion, reciprocation and vibration - into one easy to use benchtop unit. Following on the success of the smaller PS-M3D system, the first platform shaker to offer the three programmable shaking modes, the PSU-20’s mixing functions are fully programmable and can be set for continuous or timed operation (1 min to 96 hours) to achieve optimum mixing either in a single mode or in any different combination of the three functions.
