Cosasco Bio-Probes for the 2" system are used to suspend sample elements in the area to be monitored. Attached to the bottom of the solid plug by means of a left handed thread, the bio-probe also serves as a primary packing retainer.

The bio-probe has five sample elements, each with an exposed frontal area of 1cm2. Each time a sample is required for analysis a successive element is removed and replaced with a new one, leaving the other four in place. With this successive change of elements, a longer exposure is obtained for each element, but still permits a relatively frequent sample to be taken for analysis.

Features

• Meets NACE MR0175 and MR0103
• Five Sample Elements for Analysis
• Material — 316 S.S.

The bio-probe has five sample elements, each with an exposed frontal area of 1cm2. Each time a sample is required for analysis a successive element is removed and replaced with a new one, leaving the other four in place. With this successive change of elements, a longer exposure is obtained for each element, but still permits a relatively frequent sample to be taken for analysis. For example, a sample may be removed every two weeks, but each element will have a 10 week exposure to the process fluid. Formulas for sizing the Bio-Probes are shown to the right.

Benefits

Early detection is the key to controlling MIC once it has infected the system. Once the microorganisms have formed a bio-film, they become more resistant to biocides and can rapidly grow if not detected and controlled. Cosasco retrievable and retractable bio-probes offer:

• Simple and economical means of collecting bacteria samples
• Indicator for effective use of biocide treatments, reducing costs and minimizing dangerous effects to environment
• Flush Probe design ideal for frequently pigged pipelines
• Use in high or low pressure system, without the need for system shutdown

Applications

MIC is most commonly found in systems that contain metal alloys that are most susceptible to corrosion, including mild steels, stainless steels, aluminum alloys, copper alloys, and nickel alloys. Bio-probes offer plant operators a simple and effective solution.
