A separatory funnel for the work up of chemical reactions, extraction or separation of liquid phases. The separatory funnel has multi-functional features, which can be used as regular separatory funnels, Erlenmeyer flasks, and filter funnels. A method is also provided of separating a mixture of at least two immiscible liquids with solids or precipitates so that the clear liquids can be separated.

Techniques for separating cuttings from liquid include circulating a drilling fluid that comprises a liquid and formation cuttings to a scree of a screen assembly that includes screen sections; vibrating the screen assembly during circulation of the drilling fluid; while vibrating the screen assembly, separating the liquid from the plurality of formation cuttings; while vibrating the screen assembly, separating a first portion of the formation cuttings of a first size from the drilling fluid with a first screen section; rotating the screen assembly; subsequent to rotating the screen assembly and while vibrating the screen assembly, separating a second portion of the formation cuttings of a second size different than the first size from the drilling fluid with a second screen section; directing the separated liquid through the screen assembly to a liquid outlet; and directing at least one of the first or second portions of the formation cuttings to a cuttings outlet formed in the screen.

A disposable filter for a sink including a substantially inverted disposed conical filter having a rounded conical apex and a continuous horizontally disposed circular bottom rim. A circular top rim is continuously disposed on a top surface of the bottom rim of the filter. A concave-shaped indentation is continuously disposed through each of an exterior edge of the bottom rim and an outer surface of the top rim. A plurality of tabs is attached to the outer surface of the top rim. An adhesive layer is disposed on a bottom surface of the bottom rim of the filter. The filter is removably disposed atop an exterior surface of a sink, with an exterior edge of the indentation disposed around an exterior surface of a base of a faucet.

A filtering system (10) includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter (14) for coupling the filter unit to the receptacle, and also includes a base (12) having a cradle (26) for receiving the filtering apparatus and a base vacuum delivery port (28). The adapter includes an adapter vacuum receiving port (22) 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 (52, 54) 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 (30) constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.

A method of loading stacked strainers in a dispenser while minimizing strainer contamination is disclosed. The method includes providing a stack of strainers that is enclosed in a protective material to form a pod, placing the pod within a dispenser, and removing the protective material from the pod of strainers while the strainers are in the dispenser. The strainers dispensed from the thus loaded dispenser avoid being contamination during loading. The protective material may be perforated to facilitate removal from the stack, and include an extended portion to be grasped during removal from the dispenser.
