The slow pumps are currently operated independently of the main eVOLVER GUI and pump liquid at a rate of X mL/min.
The eVOLVER slow pumps currently operate exclusively through the command line. The navigate to the run_slow_pumps.py file similarly to starting an experiment via command line.
In the run_slow_pumps.py script you only need to modify one of two lines for time settings, one for modifying specific pumps and the other for modifying all pumps
Modify specific pumps timing
Modify all pumps timing
Traditionally it takes about 200-300 seconds to fill the lines with liquid using the slow pumps, however this is dependent on the length of tubing.
