Greetings PFers.

I'm designing an experiment that needs to take elemental selenium gas at 500K at 120 PSI to a liquid form at any temp and pressure. I would like to use capillary tubes in conjunction with a pump to convert the gas to a liquid.

However, i'm having difficulty finding information on capillary action when using elemental selenium. Primarily, what material do I need to use and what inside diameter. Can anyone point me in the right direction or give me a tip?

Thanks!

check this paper out. its old but they used a Ubbeholde type viscometer. they describe capillary diameter and material.
