A variety of stirrer & stirrer drives are available to use glass vessels as agitated reaction equipment.

1. Stirrer material of construction: Glass, Stainless Steel or PTFE Lined.
2. Stirrer Design: Impeller stirrer with blades, Vortex stirrer, Propeller Stirrer & anchor Stirrer.
3. Stirring Drive: Non-flameproof or Flameproof stirrer drive, 192 RPM with Variable Frequency Drive.
4. Stirring Assembly: Stirring Assembly with bellow seal or with mechanical seal.


Stirrers are assembled in a vessel using a chuck, seal and a reducer. A typical arrangement of stirrer fitted in a vessel is shown in the diagram.

CHUCK & SEAL

This unit is suitable for use under corrosive conditions. Only glass and PTFE are exposed to process fluids. Bellow seal can be used under vacuum down to 10mm Hg absolute. Mechanical seal can be use under vacuum 1mm Hg absolute or under pressure permitted into glass vessels. Generally a reducer is require to connect the chuck and seal to top neck of the vessel.
