Re: Reflux splitter
Might I just add a minor note to your very useful notes on dividing
I, too, was intersted in seeing the flow of reflux. I found glass
tube exceptionally easy to work with and under heat could bend 1/4"
tube just about wherever I wanted it - a darned sight easier than
However, at that stage I didn't have proper needle valves, and I
would say, that though one can see the signs of flow, they are not
great. Narrower glass tube would concentrate matters, though I would
keep to the accuracy of needle valve control.
The joins to the copper tube were made from ordinary poly tube and
butt-ended, so the absolute minimum of poly was exposed.
