Sublimation apparatus is a piece of laboratory glassware used in the technique of sublimation usually used by chemists to purifycompounds. Typically a solid is placed in a vessel which is then heated under vacuum. Under this reduced pressure the solid volatilizes and condenses as a purified compound on a cooled surface, leaving the non-volatile residue impurities behind. This cooled surface often take the form of a cold finger. Once heating ceases and the vacuum is released, the sublimed compound can be collected from the cooled surface.

Not usually but if the water softener's resin is leaking into the water supply - to your sink and washing machine - that could explain the orange stains because some water softener resins are orange in color. If the resin vessel is cracked the water softener is only fit for scrapping. It is not usually economic to get a water softener repaired by fitting a new resin vessel as other parts will also be worn out. If you buy a brand new one it will normally come with at least one year's warranty. In an older home sometimes rust from non-copper plumbing will stain your washing.

Copper is a metal which is acidic in nature. Thus if curd is stored in copper vessel, it shall react with the curd and turn the curd poisonous.
If the vacuum pump is on, the water will continue to boil. If the vacuum pump is off as the vessel is sealed, the boiling will stop at a point of equilibrium.
