Capillary action with elemental Selenium

AI Thread Summary
The discussion centers on designing an experiment to convert elemental selenium gas into liquid form using capillary tubes and a pump under specific conditions of 500K and 120 PSI. The main challenge is finding reliable information on capillary action related to elemental selenium, particularly regarding the appropriate materials and inner diameters for the capillary tubes. A suggested resource is an older paper that discusses the use of an Ubbeholde type viscometer, which includes relevant details on capillary diameter and material suitable for this application.

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.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'
I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
