<p class="MsoNormal">Dear Anastasia,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The leakage at the loading station is not a malfunction but a design feature. We thought our leaking station was defective, but Gatan responded that the Elsa station is not supposed to be filled with nitrogen to the level where is starts
to leak (if you look closely, there is a small hole through which liquid nitrogen escapes). The grid is not supposed to be covered with liquid nitrogen; it is kept cold with nitrogen vapors. This makes me somewhat uncomfortable but the approach seems to be
working fine. As for the holder’s performance, we have only used our Elsa a few times, and I cannot comment on consistency of ice quality. The hold time, however, is amazing: 11 hours confirmed.<o:p></o:p></p>

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I would be grateful if someone of you could share some more information related to the ELSA cryoholders.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">We extensively tried out the ultra-low profile (ULP) tip for 2 weeks and the results were quite controversial.
<o:p></o:p></p>
<p class="MsoNormal">The stability of the holder was amazing in comparison to our 626 cryoholders but there was a regular appearing of leopard/orange skin on the grids.
<o:p></o:p></p>
<p class="MsoNormal">We believe that this might be related to leakage at the loading station but I wonder if someone else had the same experience with its own ELSA (ULP or standard tip profile).<o:p></o:p></p>

<p class="MsoNormal">While I don't know anything about the holder, I find the name "Elsa" a bit humorous. For anyone with young kids who has watched the movie Frozen, you know that Elsa does two things: (1) She turns everything she touches to solid ice, and
(2) She always wants to "let it go." Both of those things are undesirable for cryo holders! :-)<o:p></o:p></p>
