VM cleaning

Putting older posts here. Going to try to keep the novice forum pruned about 90 days work. The 'good' old stuff is going to be put into appropriate forums.

VM cleaning

Post by Cmonster »

%^&*% - firstly my apologies, the forum search demands that words are at least 3 letters long - so a search under this topic was not successful.

So ...

I'm about ready for a cleaning run on my VM still. I have a 50mm column that is 1.7 metres high. On top is a cooling coil and just below this is a horizontal takeoff to a gate valve with a liebig condensor that is 1 metre long.

If I understand the principles of VM right, then only the alcohol (ethanol plus some of the lower temp components) from a normal run will find its way down the liebig. As I want to do a water and white vinegar run, I suspect this would not clean the liebig part.

Is it appropriate to put a rag plug in the top of the column providing the gate valve is open and thereby forcing the mix down the liebig?

What kind of ratio of vinegar to water should I use?

thanks ... itching to do a real run now :P
