We used simply glass fiber filters, which can be moistened with the liquid
you prefer for the removal of tritium. When being put into the cocktail
(any cocktail) they are perfectly transparent. No dissolution is necessary.
When using water for moistening you can use membrane filters as well,
because they become transparent in the cocktail and the cocktail penetrages
them.
