That station is now 8 years old. I suspect the older stations are more robust. We often filled the transfer station with LN2 such that grid could be kept submerged (transfer ice is a real issue if working in cryo gas in Florida). However, we were careful not to overfill the transfer station such that the LN2 overflowed the working chamber of the station. We also let it warm up to RT by itself in most cases and less frequently used a hair dryer to carefully warm it.<br></div><div><br>Duncan<br></div><br><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"Michael Braunfeld" <braun@msg.ucsf.edu><br><b>To: </b>3dem@ncmir.ucsd.edu<br><b>Sent: </b>Thursday, September 6, 2018 11:59:14 AM<br><b>Subject: </b>[3dem] Leaking loading stations<br><br>Hi All,<br><br>Do other facilities have any issues with the loading stations for the <br>Krios/Arctica?
