- Model 1080 - Water Sampling Bottles



The GO-FLO sampling bottle feature a close-open-close operation. Opens automatically (hydrostatic pressure activated) at approximately 10 meters (33 feet), then flushes until closed by standard GO Devil messenger (model 1000-MG) individually, serially, or sequentially by remote command with a model 1015 Rosette multibottle array, or with model AR1015 Acoustic Command Control. Inert gas can be injected into bottle to force retrieved sample out of sampling valve, directly through filter system.

The GO-FLO sampling bottle avoids sample contamination at the surface, internal spring contamination, loss of sample on deck (internal seals), and exchange of water from different depths.
