Cold trap bath is the laboratory device specially designed to convert or condense the gases except the permanent gases into volatile substances. It is generally consists of the cooling bath which is filled with liquid like liquid nitrogen, acetone or dry ice which causes the fall of the temperature to their lowest points. When gas passes through the cold trap the decreased temperature condenses the gas & captures in the trap by removing its gas phase. These prevent vapours entering in vacuum pump which can cause contamination
