Roger, curious if you know of anyone running a peristaltic pump on a 3171. My 3171 keeps putting out lower amounts. Turn it to 25ml minute and over a couple of days it is 15. Not sure why. Co2 pressure does not change. Sump is kept clean. Any thoughts or possible issues running a peristaltic pump for effuelt stability.
I have a masterflex on hand.
