Don't know if it'll work in your set up but I'm using a foot mounted
needle valve (Radiospares # 262-0713) mounted below the horizontal leg of
a Nixon-Stone condenser head. The needle valve is connected to a ¼"
BSP male - male stud coupling (RS # 234-8821) mounted in the bottom of
this leg via a short length (1½") of ¼" OD copper tube. I cut a wide slot
across the end of the stud coupling inside the horizontal leg, the bottom of
this slot being flush with the inside surface of the tube & orientated fore & aft
before being soldered in place. Reason - to ensure that the condensed
distillate flows over the reflux outlet rather than round it. If you've not been
there RS have an excellent web site & you can order items on-line from it.
Hope info is of use.
