What’s up gang
So I have been running a 2 liter system for a while and have it dialed in pretty well. As a circulator I was using a bucket heater and aquarium pump but just ordered (Chinese supplier) a 10L turnkey system that came with a vacuum pump and low temp circulator
I am struggling to get the circulator above 35 degrees Celsius. Even when I make the set point 100 degrees it won’t go over 35. I am using 710spirits ethanol/heptane mix as my medium.
Past that the mantle over shoots temps like crazy and seems to have a better chance of stabilizing under vacuum. Either way I was pulling ridiculous vacuum on the system -30hg on my gauge and had to scale my temps all the way up to 267 degrees before getting a reaction. Can anyone make any suggestions or give me some questions to answer to help you help me? Here’s a pic of my setup
