[PSUBS-MAILIST] idea

[Sean T. Stevenson via Personal_Submersibles]

Hank, the way this is typically done in the field (based on my experience with CTD sampling), is that the sample containers are normally open, such as a plastic tube with e.g. o-ring sealed end caps which are connected through the tube with a length of bungee. The caps are pivoted to the open position and locked via some sort of trigger device, which when activated, simply releases the caps which snap into position on both ends, sealing the sample tube.

With pumped water sampling, I am familiar with a carousel of tubes, like a revolver, in which only one tube is opened and in-line with the sampling system at any time. As a tube rotates out of position, it is face sealed, again with O-rings, by the encapsulating plates. The tubes are subsequently emptied one by one into sample bottles topside.

Not sure if that's useful info. It has been decades since I have worked with any of that stuff.
