Liquid filter assemblies including an upper sample reservoir, a sample filter and a lower storage bottle are supported by a vacuum base. The base has a vacuum inlet port and, for connection to the liquid filter assembly, a vacuum outlet port. A vacuum is provided through the base to below the sample filter to draw sample liquid through the sample filter into the storage bottle. The base may include an auxiliary vacuum outlet port for connection with additional devices. The bases may be connected from one to another through auxiliary vacuum outlets and the vacuum inlets to make a chain of liquid filter assemblies supplied from one vacuum source. Alternatively, one base may include multiple vacuum outlet ports so that it may support and supply vacuum to a plurality of liquid filter assemblies.

Vacuum base and related methods and apparatus for vacuum filtration

Methods for vacuum filtration

A method of removing a filtrate storage bottle from a water bath includes inserting at least two finger underneath a radially protruding lip of a filtrate storage bottle sealing cap and raising the at least two fingers to lift the bottle from the water bath. A side wall portion of the filtrate storage bottle sealing cap is smaller in perimeter than a circle surrounding the radially protruding lip. The cap creates a liquid tight seal with the filtrate storage bottle.

Filtrate storage system

A portable fixture for supporting a vacuum filtration device includes a cradle portion and a clamping portion. The cradle portion supports the vacuum filtration device. The clamping portion removeably attaches the portable fixture to a support in order to secure and support the filtration device above a workspace. The portable fixture may also provide a vacuum to the filtration device. To that end, the portable fixture may have a vacuum inlet port which may be connected to a vacuum source and a vacuum outlet port that is fluidly connected to the vacuum inlet port.

Apparatus for supporting a vacuum filtration device

A flow diverter, vacuum control and tilting of the liquid filtering system are used alternatively or in conjunction to reduce foam production in a filtered liquid sample. A liquid filtering system includes an upper sample reservoir, a filter and a lower storage bottle. A vacuum is applied below the sample filter to draw sample liquid through the sample filter into the storage bottle. A flow diverter may be used to direct flow of the filtered liquid sample onto a sidewall of the storage bottle or guide flow to a bottom of the storage bottle. The vacuum may be regulated to reduce foaming. The liquid filtering system may be tilted to direct fluid to the sidewall of the lower storage bottle and reduce foaming.
