Specifications: • Pressure Rating — 1500 PSI (10.3 MPa) • Mounting — 1 V2" Full Port Valve Minimum • Temperature Rating — +500° F/+260° C • Material — 316 SS • Five Sample Elements for Analysis • Meets NACE MR0175 and MR0103 • Seal Material — Teflon® The bio-probe is used to collect samples of bacteria in Oil and gas systems, including refineries, offshore platforms, pipelines, etc. Bacteria may be present in a system as either sessile (attached to the metal surface), or planktonic (present in the process fluid). There can be considerable differences between the types of bacteria present in either of these two forms. From a corrosion perspective, the sessile bacteria are the ones that are of primary importance since these are the ones that affect the corrosion, and the ones that must be controlled with chemical treatment. For this reason fluid samples for testing of bacteria only test for planktonic. The Model 6215 Bio-Probe provides a retractable means of collecting samples of bacteria in processes at pressures up to 1500 PSI/1o.3 MPa and temperatures up to 500°F /260°C. COSASCO® Bio-Probes are used to suspend sample elements in the area to be monitored. Insertion of the bio-probe can be adjusted to permit electrodes positioning at precisely the desired point within the process. Standard lengths are available in 18, 24, 30 and 36 inches. A safety clamp assembly is recommended at pressures above 100 PSI and temperatures above + 150°F. 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
