 Brian, I have one of those, they are called sample suckers and use a thruster to suck water and samples into a clear container.Its only good for one sample per dive.Hank

 Hank,    I attended a talk about the Santa Barbara natural oil seeps a few weeks ago up at UCSB,  they were using Alvin and collecting data similar to what you're talking about.  What they did was have an evacuated tube with a valve on it , the arm hand would turn the valve letting the sediment into the tube and then they would turn the valve back off.   Thinking about it it seems like once you got below 33 ft. there would be no vacuum,  so I'm not sure how they did that, unless a pump was involved, but I seem to remember it was just a vacuum.

 The tubes only need to hold 30 cc and the containers only have to hold the material from spilling out and possibly contaminating the sample next to it, and they will be full of water.  Alan, I am looking for something ready made.Hank

 HI Hank,
what is inside the tubes before they are opened?   (I'm worried that if they are empty - 1atm of air - they will be hard to open at depth)Who sealed do they need to be before and afterwards? (E.g. like jam jars with loose lids, or something hermetically sealed)
Also, that size tubes are you looking to use?
Cheers,  Ian.

 Do you want the lid to close back up by itself ?

Okay fellow submarine nerds, I need an idea.  I need to find containers for taking samples off the bottom that when they are squeezed they open a lid.  Ideally I would grab each container from a rack and when I grab it the lid opens from the force of grabbing it.Hank_______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles_______________________________________________
