I tried to make a heat tube using R134a, which is similar to R22. I didn't have much luck.

I have a standard vacuum pump goes down < 50 microns, standard multi way connection hub and hoses etc and a digital gauge so you can measure it with any accuracy.
As the amount of liquid gas in the tube is small, say 100cc in a 10m pipe you need to construct a small charge tank that can be filled from the main bottle of refrigerant. Once evacuated, the contents of the charge tank fills the heat pipe.
Ideally the gas should be a single component, not a mixture of gasses.
