Micro scale vacuum distillation
Microscale vacuum distilation can be a pain and often lead to low yields...
try this setup

Problem here would be that the slightest bit of bumping and the sample your collecting will be contaminated. I prefer to have the glass vial after
the condenser in the more traditional way. You can chill the collection flask to help with the collection.

You apparently haven't seen the way vacuum distillations can bump.

well that is a factor that would have to be dealt with.. the thing here was to make the yield higher when working with tiny quantities

I have used this type of apparatus for microscale distillations with good results.
Amounts have been >1ml though. Might be too big for <1ml.
