Digital shakers with microprocessor control which are ideal for mixing applications with heavy loads, e.g. cell cultures, solubility studies and extraction procedures. Variable speed control provides consistent, uniform shaking action. The Accu-drive shaking system delivers exceptional speed control, accuracy, safety and durability, the system continuously monitors shaking speed and will maintain the set point even under changing loads.

• Two independent LED displays show speed and time
• Integral timer, 1 s to 160 h, shows elapsed time or counts down, automatic switch off and audible alarm when program is complete
• Can be used at −10 to +60 °C (max. 80% relative humidity, non condensing), in an incubator, CO₂ incubator or cold room
• 5 year warranty on motor and drive mechanism

Displayed speed is accurate to 1% of set speed (when speed is above 100 min⁻¹). The ramping feature slowly increases speed to the set point for added safety. Built-in load sensor can detect an unbalanced condition and will automatically reduce the min⁻¹ to a safe speed to prevent spills and protect samples. Speed calibration mode allows the user to recalibrate the speed display and RS232 serial port provides two-way communication for data logging and unit control.
