Abstract:
A series of vertically oriented filters of decreasing pore size is sealed from the atmosphere. Pressurized gas is used to force the liquid to be filtered through the filters. The filter stages are thermally insulated from ambient temperatures in order to maintain the liquid passing through at a reduced temperature. Each filter stage has a removable lid, which provides convenient access for replacing the filter cartridge, allowing it to be changed without disturbing the thermally insulated sidewalls of the filter stage.

Claim (Index 1):
A filtration system comprising a solvent vessel, a plurality of filter stages and the same plurality of transfer tubes wherein:\n each filter stage has:\n a thermally insulated cylindrical side wall; \n a lid that is removable from said wall; \n a replaceable, elongated filter cartridge; \n a support having a surface that positions a base of said filter cartridge centrally in the filter stage; \n an inlet port in the lid located to introduce liquid into the filter cartridge; \n an inlet port located to introduce pressurized gas into the filter stage outside of the filter cartridge; and \n a base with an outlet port that drains fluid from outside the filter cartridge; the solvent vessel has: \n a thermally insulated side wall; \n an inlet port for introducing pressurized gas; and \n an outlet tube having a first end located at a bottom region of the solvent vessel and a second end located outside the solvent vessel; \n and the transfer tubes are each removably connected:\n at an outlet end thereof to one of the inlet ports in one of the lids of he filter stages; and \n at an inlet end thereof to either the second end of the outlet tube of the solvent vessel or the outlet port of another of said filter stages such that the solvent vessel and the filter stages are connected in series.
