Model 1080 GO-FLO Water Sampler


Close-open-close operation. Opens automatically (hydrostatic pressure activated) at approximately 10 meters (33 feet), then flushes until closed by standard GO Devil messengers (Model 1000-MG) individually, serially, or sequentially by remote command with model 1015 Rosette@ multibottle array, or with model AR1015 Acoustic Command Control. (See data sheet 1015-12/85). 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.
Cable clamps on 1.7 to 12-liter bottles are for cable diameters up to and including 6.4mm(1/4"). Clamps on larger bottles are for diameters up to and including 8.0mm (5/16").
Rigid PVC tube section, ball valve, handles and cable clamp blocks. Delrin stopcocks and push rod. Stainless steel cable clamp bolts. Latex external spring, Viton and silicone O-ring seals (other materials available). Monofilament nylon and Kevlar lanyards. Inert Gas Connection: Dual-purpose air vent pressure release valve with standard 9/16-18 thread for connecting inert gas line. (Operation requires additional fitting - part S1080-AFIT).
End Closure:
Ball valve with Viton and silicone seals.
Thumbscrew air vent at top. Stopcock at base. Stopcock diameter for 1.7- to 12-liter bottles is 4.7mm (.187"). 20- and 30-liter bottles have a second, larger stopcock diameter (9.52mm, .375"). 60-, 90-, and 100-liter bottles have one stopcock 19.05mm (.750").
See overleaf for dimensions and weights of 1.7-,2.5-,5-,8-,10-,12-,20-,30-,60-,90- and 100-liter bottles.
