Complete Assembly Instructions
The unjacketed process reactor, the fully assembled reactor head, stirrer shaft & agitators, Tru-Stir™ stirrer
shaft coupling, flake retaining cup, PTFE stirrer bearing, temperature probe & adapter, and motor are shipped
assembled on the support frame. Use the following instructions should you need to remove or adjust these
components.
1. Attach the zero dead space drain valve (CG-1968-Q)
coupling (CG-1968). Tighten the coupling to the specified torque setting.
2.
ring. Replace the front reaction vessel clamp and tighten the torque knobs evenly until you hear a
3. Place the 200mm Perfluoro o-ring into the groove of the reaction vessel flange.
4. Assemble the stirrer shaft, agitators, and PTFE flake retaining cup and lower into the reaction vessel.
5. While lowering the reaction vessel lid onto the vessel, carefully insert the end of the stirrer shaft
through the 45/50 center neck of the lid. PLEASE NOTE: THE PTFE STIRRER BEARING IS NOT
INSERTED IN THE HEAD AT THIS TIME.
6. Dismantle then slide the PTFE stirrer bearing over the end of the stirrer sh
center neck, sealing the o-ring.
7. Position the powder fill port towards the front of the reactor.
8. Secure the vessel and lid together with the quick release PTFE coated clamp, making sure the entire o-
ring is seated in the groove. Adjust the threaded bolt to improve the seal around the flange.
9. Attach the Tru-Stir stirrer shaft coupling to the 1/4 HP electric stirrer motor shaft. Then attach the
motor to the support frame via the supplied four socket head cap screws.
10. Insert the end of the stirrer shaft into the stirrer shaft coupling and tighten the collar with an Allen
wrench. Check the vertical alignment of the reactor and adjust if necessary.
11. Tighten the black compression nut on the PTFE stirrer bearing, which compresses the bearing onto the
stirrer shaft.
12. Attach the electric stirrer motor controller and the digital temperature monitor to the support frame via
13. Attach the control cord from the electric stirrer motor to the rear panel of the controller. Make sure that
the speed control knob on the controller is turned completely off BEFORE turning the controller on. If
using the air motor, attach air source to the motor. The brass needle valve on the back of the air motor
should be CLOSED.
14. Loosen compression nut and insert the thermocouple thru the thermocouple adapter and then insert the
adapter into the desired side neck. Adjust the depth of the thermocouple by tightening the Chem-Thread
at the top of the adapter. PLEASE NOTE: CHECK TO SEE THAT THE THERMOCOUPLE DOES
NOT COME INTO CONTACT WITH EITHER OF THE AGITATORS BY MANUALLY
TURNING THE STIRRER SHAFT. Attach the thermocouple cord to the probe then to the
temperature monitor.
15. Place the digital temperature controller on the side stand and plug in heating jacket, lower heating
mantle and thermocouple.
16. Attach the condenser and any other peripheral glassware.
