Abstract
A reversible vacuum filter cartridge for connection to a pair of tubes or other entities to filter a liquid medium placed in one of the tubes or other entities is described. The filter cartridge is comprised of a male coupling and a female coupling. The couplings are interconnected to one another by simply pushing a mating projection of the male coupling into a mating cavity of the female coupling. A connecting port is provided in the male and female coupling and has a conduit communicating with tube connecting ends of each of the couplings which communicate with an open end of a tube connected to each of the couplings. The connecting port is identical in each of the couplings and serves either as vacuum port or an air intake port. A filter disk is retained captive between perforated outer walls of each of the couplings when interconnected together in fluid-tight relationship.
