The Grant bio PSU-20i is a powerful and efficient microprocessor controlled multi-functional orbital shaker providing all that is required – rotation, reciprocation and vibration – for thorough mixing in flasks, beakers, Petri dishes and other laboratory vessels.

• Orbital motion, reciprocation and vibration functions all in one product
• Reliable direct drive system
• Fully programmable sequence of functions
• Simple to set up and easy to operate
• Interchangeable platforms, including multi-level platform option
• Loads up to 8 kg
• Orbital and reciprocating speed: 20 to 250 rpm
• Reciprocal rotation: 30 to 360º turning angle
• Vibration: 0 to 5º turning angle, programmable in a burst of 0 to 5 seconds
• All mixing functions – orbital motion, reciprocation and vibration – can be set for continuous or timed operation, or be linked together in different combinations to ensure optimum and accurately repeatable mixing conditions for your application
• Direct drive system
• Brushless motor for longetivity
• Powerful, reliable and exceptionally quiet motor –  combines 8 kg loading capacity with consistent even motion and quiet operation
• Very easy to operate, with simple set-up of multi-segment programs via push buttons and the 2-line LCD status display. Microprocessor controls for making corrections without stopping the program.
• Universal detachable platform can accommodate vessels of different shapes and sizes for maximum flexibility.
• Optional flat platform PP-20 with non-slip mat accommodates low profile containers. Can be extended to create up to four levels to maximise the throughput per cycle.
