| Definition | A plastic free-flushing water sampling bottle with a capacity of 1.7-100 litres. The tube is composed of PVC and has ball valves with Viton and silicone seals at each end joined by an external latex spring and nylon and Kevlar lanyards. It is closed when deployed then opens automatically (hydrostatic pressure activated) at approximately 10 m and flushes until closed. When the bottle reaches the desired depth the lanyards are released by a pressure-actuated switch, command signal or messenger weight and the caps are forced shut and sealed. Bottles may be deployed singly clamped to a wire or in groups on a rosette. A reversing thermometer assembly may be attached to the bottle. When extracting water from the bottle, inert gas can be injected into the bottle to force the sample out of the sampling valve. The GO-FLO sampler avoids sample contamination at the surface, internal spring contamination, loss of sample on deck (internal seals), and exchange of water from different depths. | ||
