1. High Pressure Vessels Part 1 4 Polymerization reactors 2x25 mL, 2x100 mL

2. High pressure reactors should only ever be operated by trained person
Operation Conditions – 100 mL reactor
High pressure reactors should only ever be operated by trained person

3. Operation Conditions Pressure: 200 Bar Volume: 100 mL
Operating temperature:
from -10 °C to 350 °C
Year built: 2012
These are maximum reaction conditions, for safety keep within 2/3 of these values
25 mL reactor, 6 mL of monomer to be used
100 mL reactor, 15 mL monomer to be used

4. Operation Conditions – 100 mL reactor
The seal is formed by the metal groove
and the PTFE (polytetrafluoroethylene) O-ring
Note that the O-ring can easily be replaced

5. Split-Ring Clamps

6. High Pressure Vessels
- Remember to tighten screws on opposing sides of the split-ring clamps such that the reactor remains balanced
- Do not over tighten screws

10. Safety High Pressure Vessels
No lone working is permitted
Be sure that the CO2 cylinder is securely fastened.
Periodical leak test in the CO2 regulator, lines and reactor.
Use personal protective equipment PPE (specs, gloves, coat).
Be always aware of the vessel temperature and pressure!
Don’t inject your reaction mixture into the pressurized reactor.
Let someone know if you are unable to open or tighten the reactor.
Let someone know if you have noticed any problem with the temperature, pressure or reactor.
