Abstract: The present invention relates to processes for the rapid detection, semi-quantification and quantification of live microorganisms in solutions or suspensions using immunomagnetic particles, without requiring pre-enrichment through culture of the microorganism. The invention also relates to kits for carrying out said processes and to the quantification of the microorganisms detected by means of automated biosensor equipment.

Abstract: The present invention relates to a low pressure water filter and dispenser system for use in a refrigerator which enables an effluent from said system exhibiting a log 6 bacteria reduction and a log 4 virus reduction with pressures as low as 0.35 kg/cm2 (5 psi). The system can be located in various places, for example it can sit on the shelf, it can be mounted to the ceiling of the refrigerator, or it can be attached to the wall or other internal components.

Abstract: An apparatus for filtering and recirculating oil used in a vacuum pump is disclosed. The filtration device comprises first and second valves permitting, respectively, addition and deletion of oil from the system. A plurality of filter elements are provided to remove particulate contamination from the oil. In a preferred embodiment, the vacuum pump is situated in an enclosure which retains therein the latent heat produced by the vacuum pump. Alternatively, an oil heater may be provided. The oil is preferably maintained at a temperature of greater than about 40.degree. C., so that the particulates entrained therein remain in a sludge.
