First walkthrough SPD

First run through with short path distillation. Need a hand. Mantle is up to 220 with no reaction. I let it slide to 250 with no reaction as well. It starts to vaporize but then doesn’t travel up the neck.

It is almost certainly a vacuum leak. Do you have a vacuum gauge?

Yes I do. I’m just not sure how to check it

Post a picture of it.

Thanks. Yeah most def. I have all of summits short path info in front of me. Think I found the leak. Thank you. Will continue to post if need be and of course thank you for your knowledge sir

Could it all be a problem with heat no traveling up the neck far enough? When I had the mantle at 200 there was vapor but it wasn’t traveling through. Or is that the leak doing that. I have another gauge on the vacuum not digital and it reads -1, no leak

That gauge says “atmosphere”, AKA no vacuum at all. So you have either a critical leak or your vacuum pump isn’t working (or did you forget to turn it on)?

Looks like you have no vacuum
