Stirrer Shaft and Agitator Assembly
The stirrer shaft and agitators are assembled and installed when shipped. Use the following instructions should you need
to remove or adjust these components.
Components Needed for Stirrer Shaft and Agitator Assembly:
1ea CG-2097
Stirrer Shaft
1ea CG-2093
Flake Retaining Cup
1ea CG-2095
Upper PTFE Agitator
1ea CG-2096
Lower High Viscosity PTFE Agitator
1. The lower agitator assembly (CG-2096) is placed on the end of the stirrer shaft aligning the hole on the stirrer
shaft with the holes in the PTFE hub. The sand blasted portion is the lower end of the stirrer shaft. Insert the
glass filled PTFE pin. The pin must be cut to 24mm long before installing. Tighten the compression fitting.
PLEASE NOTE: THE PTFE PIN MUST BE INSTALLED BEFORE USING.
2. The upper agitator assembly (CG-2095) slides over the end of the shaft. The height from the bottom will depend on
the total volume you intend to run in the reactor.
3. Once you have the upper agitator in place, tighten the compression fitting as tight as possible (by hand). For use at
higher temperatures, Chemglass recommends heating the upper agitator hub with a heat gun and then retightening.
Then tighten the set screw on the flat of the stirrer shaft using a screwdriver. This will minimize the possibility of
the agitator falling or slipping at higher temperatures.
4. The PTFE flake retaining cup (CG-2093) slides over the top of the stirrer shaft and is positioned approximately 18
inches from the bottom of the lower agitator assembly (CG-2096). For the cup to work effectively, the final position
will have to be adjusted so that it is not less than 1 inch away from the bottom of the PTFE stirrer bearing.
