This technology enables the preparation, incubation, and analysis of water samples in the field without the need for any ancillary equipment. With simple visual examination (the most trusted and accepted method of enumeration), unskilled users can successfully conduct E. Coli/Total Coliform water tests outside the laboratory with quantitative results in as little as 12 hours.
The invention relates to a device and method for preparing and testing a fluid sample using a filtration procedure for analysis of a filterable constituent of the fluid. In particular the process employs an enclosed pathway whereby the fluid sample is initially put into a sealable flexible containment-vessel, then it is passed through a fluid passageway to a removable enclosable filter cartridge, wherein the filterable constituent is removed and the resultant filtrate fluid is discharged from the cartridge. Once introduced to the flexible vessel, the enclosed pathway system thereby enables the fluid to be filtered and the filterable constituent examined with minimal complications of contamination of the sample through exposure to environmental pollutant external to the fluid sample.
