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.</font></font><div><font face="Arial, sans-serif" size="2"><br clear="none"></font></div><div><font face="Arial, sans-serif" size="2">Brian</font></div><div><font face="Arial, sans-serif" size="2"><br clear="none"></font></div><div><font face="Arial, sans-serif" size="2"><br clear="none"></font><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">--- personal_submersibles@psubs.org wrote:</span><br clear="none"><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">From: hank pronk via Personal_Submersibles <personal_submersibles@psubs.org></span><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">To: irox via Personal_Submersibles <personal_submersibles@psubs.org></span><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">Subject: Re: [PSUBS-MAILIST] idea</span><br clear="none"><span style="font-family:Arial, sans-serif;font-size:10pt;">Date: Mon, 20 May 2019 21:12:19 +0000 (UTC)</span><br clear="none"><br clear="none"><div style=""><div></div>
<div>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.</div><div>Hank</div><div><br clear="none"></div>
