Grant Bio PSU-20i Orbital Multi-Platform Shaker


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.

Suitable for use in different laboratories in microbiology, chemistry, immunology, biochemistry and molecular biology.

  • 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.
