Fluid temperature is maintained at 20°C for 10 minutes.
2 20°C 15 minutes
Controller cools fluid to 10°C set point programmed for
Step 3. Ramp rate is based on the 15 minute step
duration.
3 10°C 15 minutes Fluid temperature is maintained at 10°C for 15 minutes.
4 10°C 1 hour
Controller slowly heats fluid until 50°C set point
programmed for Step 5 is reached. Ramp rate is based
on the 1 hour step duration.
