Rotary shakerss are used in research institutes, workshops, chemical and agricultural laboratories to shake solutions in Erlenmeyer flasks. This shaker is combined with a rotating motion. The shaker is a sheet metal enamelled to specification that houses the motor, which is coupled to the pulley via a thick M.S. V belt on all sides.

Sturdy platform with adjustable neoprene rubber washers to accommodate various volume Erlenmeyer flasks. A crankshaft with ball bearings is mounted on the platform and gives the piston orbital motion with an eccentricity of about 100. The shaker has variable speed ranging from 20 to 240 rpm.

The drive motor is of standard type and is suitable for operation with single-phase 220 V AC voltage. of 50 cycles.
