Patent number: 8158009Abstract: 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.Type: GrantFiled: January 31, 2008Date of Patent: April 17, 2012Assignee: Roush Life Sciences, LLCInventors: Jeffrey F. Kane, Thomas Taylor, Peter Zuk, Jr., Sean Landis Phillips

Publication number: 20100000933Abstract: A vacuum filtration apparatus for detecting microorganisms and particulates in liquid samples. The apparatus includes a base, an absorbent pad, a filter means, a funnel and a lid. The funnel is releasably attached to the base, and may contain an integral flexible seal for releasably sealing the filter means to the base. The outer wall of the lid may be segmented to make it flexible, this flexibility allows it to be releasably attached to the funnel or the base. The apparatus is designed so that any funnel will fit any base, and any lid will fit any base or any funnel when all parts are manufactured to normal tolerances. The apparatus may contain a means to keep the filter means wrinkle free in both the dry and wet states.Type: ApplicationFiled: June 15, 2009Publication date: January 7, 2010Applicant: ROUSH LIFE SCIENCES, LLCInventor: Peter Zuk, JR.
