The PSU-15i belongs to a new generation of multifunctional mixing devices: The new design, direct drive system, brushless motor (service life
up to 35000 hours) and automatic loading balancing system make the new PSU-15i even more reliable especially for the long non-stop operation. The PSU-15i has a microprocessor control which allows real-time program correction, indication of set and actual speed, angle and time, operation timer in the display.

1. Orbital motion 
simple even circular motion - common type of motion used in shakers. Adjustable speed from 20 to 250 rpm.

2. Reciprocal motion 
vertical rotation with changing direction of rotation. Adjustable turning angle (from 15° to 360°, increment 30°) sets the limits for this type of motion. The speed is the same as set for rotational motion (from 20 to 250 rpm).

3. Vortex motion of the platform (vibration) 
intensive mixing of samples at high speed with small amplitude - Vortex motion. Adjustable turning angle of 0° to 5° (increment 1°)
