Electronic valve (solenoid?)
The reason why you can't separate substances that boil less than 40-50C apart is because the temp/pressure isn't homogenous in the pre-condensation
path, right?
Is there a piece (electronic maybe) which inserts between heated flask and claisen adapter (or vigreux) which contains a thermometer (ntc or ptc) and
solenoid valve, controlled by computer to only open the valve when a given temperature is/isn't reached?
The heating is also computer/microcontroller controlled, using the din 5 connector at the back of the hotplate

There are PID controllers that have been adapted to operate valves in all sorts of temperature control applications.
For ready made??? you will have to search around. In Lab glass I have only seen custom made bits on Youtube videos.

They tried to have me "put to sleep" so I came back to return the favor.
