Abstract
A device which in combination with a vacuum creating source and a pressurized source of a first liquid, permits all or a portion of a number of second liquids to be selectively filtered either singly or concurrently, and the particulates resulting from the filtering operation washed separately with the first liquid prior to the particulates being removed from the device. The device is of such structure that a number thereof may be connected by tubular means end-to-end to permit the separate filtering of any desired number of second liquids and the subsequent washing of the particulates from the second liquids with a first liquid from a pressurized source thereof.
