Abstract
A filtering system () includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter () for coupling the filter unit to the receptacle, and also includes a base () having a cradle () for receiving the filtering apparatus and a base vacuum delivery port (). The adapter includes an adapter vacuum receiving port () coupled to the vacuum delivery port for driving the liquid through the filter and—as filtered liquid—into the receptacle. The cradle and the adapter have an interlocking mechanism () that locks the filtering apparatus to the cradle in a locking position in which the vacuum receiving port is sealingly coupled to the base vacuum delivery port. The base vacuum delivery port has a vacuum valve () constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.
