Title:
METHOD FOR QUANTITATION OF MICROORGANISM CONTAMINATION OF LIQUIDS AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO1998004675
Kind Code:
A3
Abstract:
Use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and the like. The capsule allows a severe reduction in the water sample size tested, substantially minimizes risks of cross-contamination, and provides a leak-proof vessel for shipment. Risk of infection of laboratory personnel and time of analysis are both reduced. Costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.
