Abstract: There is disclosed a system capable of purifying water to a laboratory grade level that uses redox media, high energy catalytic activated carbon, ultraviolet radiation and high purity ion exchange media in series filtration. The system produces purified water having a specific resistance of at least 18.2 megohm·cm at 25° C. with low organic carbon content. The system is designed to be fabricated on a sufficiently small scale to fit on a lab bench top.

Abstract: A detachable and adjustable adapter assembly for directing fluid flow into and out of a dual cartridge media housing is disclosed.

Abstract: An internally plumbed housing for containing fluid purification media especially suitable for the production of ultrapure water. The device may be installed in a system for the production of laboratory grade water or may be used with pressurized feed for the delivery of purified water or other fluids in multiple applications.

Abstract: An apparatus for the treatment of gases in a positive crankcase ventilation (PCV) system, in an internal combustion engine, is provided with a housing defining a gas treatment chamber. At least one gas filtering medium is disposed in the treatment chamber, and the gases from the engine crankcase are passed through the gas filtering medium in the treatment chamber, before the gases are routed into the air intake portion of the engine. In addition, the gases, after passage through the gas filtering medium, are passed through an ionization device.

Abstract: A manually operable fluid dispensing system having a fluid dispenser connected to a fluid source by flexible tubing. The dispensing system provides a supply fluid path from the source of fluid to the dispenser and a recirculation fluid path from the dispenser to the source of fluid. A dispenser mount is rigidly attached to a support surface for releasably holding the dispenser, and the dispenser mount supports the dispenser in a fixed position for dispensing fluid therefrom. In addition, the dispenser can be removed from the mount for dispensing fluid at a remote location. A manually operable trigger is pivotally connected to the dispensing valve and has a quiescent position which closes the dispensing valve. When in the quiescent position, a trigger handle extends over an exterior portion of the dispenser body in a generally forward direction toward the dispensing outlet and forms an included angle with the dispenser body.

Abstract: A water purifier which produces ultrapure water from a variety of feed sources. The feed source water may be potable tap, distilled, deionized, or water treated by reverse osmosis. The water is passed through a first purification media (30) and then through a chamber (34) where it is exposed to ultraviolet light in the presence of titanium dioxide. The water is then passed through a second purification media (38) to a dispensing valve (40). Operating the dispensing valve (40) provides ultrapure water from the purifier having a specific resistance of at least 18.0 megohm-cm and a TOC count of less than one ppb.

Abstract: A water purifier for supplying high purity water with a low total organic carbon content. The purifier includes removable cartridges that contain a series of organic and ion exchange purification media. Special couplings are used to permit the cartridges to be easily and quickly connected to and removed from the water purifier. In addition, the cartridges contain a check valve to minimize water drainage from the cartridge when the cartridge is removed. Selected water purifier components are constructed of fluorinated polyethylene.
