Dear 3DEMers,

<div class=""><br class="">

</div>

<div class="">While troubleshooting some “leopard print” ice contamination on a Gatan 914 holder, we noticed that the <b class="">underside</b> of the cryoshield/shutter does not close 'all the way' (you can see the grid).</div>

<div class="">I wanted to know from other users of 914 holders, does the underside of your shutter look like this when closed, or does it slide further to completely seal away the grid?</div>

<div class=""><br class="">

</div>

<div class="">An alternative cause of the contamination is a leak through the shutter rod assembly.</div>

<div class="">Any thoughts welcome!</div>

<div class="">Thanks,</div>

<div class="">Teige</div>
