Abstract
A vessel into which previously used, dirtied ethylene glycol type antifreeze may be entered to be purified by sedimentation. After sedimentation is essentially completed and the antifreeze appears clear to the human eye, it may be drawn off by means of a side spigot without disrupting the sediment which has collected at the bottom. The apparatus further serves to register the degree of freeze protection of the antifreeze contained therein and serves as a storage container for the antifreeze until transferred.
