I just got my rotovap yesterday and I have not been able to make it work, so maybe im wondering if the pump is not the right pump for this job, I do not have a chiller either so im using a water pump with ice as a chiller, the coldest I was able to get the temp of the water while it circulated was 1C, I got a mini fridge and im in the process of hacking to make it work as my chiller, can I run regular antifreeze through the coil of the condenser ?
I really hope someone could help me figure out if my current pump ok for the job ? and if so, at what Hg should I set it at for best results ?
I will work but wilk injest alcohol. A diapragm pump is the right pump.
But i used a pump like yours until i got a diaphragm pump.
Keep extra pump oil around and change ot after every run
Lol it took me a few minutes to catch it. Not looking to be an asshole either @MissionAcomplished, it happens to the best of us (if that is the actual problem). Remember the prime directive: check the easiest, dumbest thing first.
no bro I wish, I do have the vacuum valve on a shut, it comes with a PTFE tube and in the manual it says im suppose to attach the tube to the feeding cock but I dont understand why
I got my chiller at -6C , the water bath at 40C im pulling vacuum at -5Hg, -10Hg and -15Hg and it does not seem to work, what could I be doing wrong ?? Any help would be amazing at this point I dont know what else to do
Heres my pic
Your is the same as mine, but a 2l maybe? I use a welch wobl for my vac pump, maxed out at -26.5hg, bf bathbtemp set to 50c, chiller runs about -11c on the led panel.
I’ve ran open tap (runoff drains into my garden storage tanks) with great results.
