<div dir="ltr">Dear Karim,<div><br></div><div>I've send samples from New Zealand to Europe on three occasions (4 dry-shippers in total), which is probably as far as anyone will ever ship grids. I had concerns but it works remarkably well. We used World Courier for shipping our CXR-100s because FedEx New Zealand wouldn't do it. Couple of lessons I learned along the way include:</div><div><br></div><div>1. Be careful with how you secure your grid boxes. I put my grids in circular boxes, which I locked with a handling rod like the one you find here (item <span style="color:rgb(0,0,0);font-family:Arial,Helvetica,sans-serif;font-size:12.8000001907349px;line-height:19.2000007629395px">71165-50 at </span><a href="http://www.emsdiasum.com/microscopy/products/grids/accessories.aspx">http://www.emsdiasum.com/microscopy/products/grids/accessories.aspx</a>). All my grids fell out the first time I send samples to NeCEN. I think thermal expansion/contraction and vibrations during transport can cause the screws to become undone. Fortunately, we had enough uncontaminated areas left despite the grid sitting completely dry at the bottom of the Falcon tube!</div><div>2. Dry-shippers conform with IATA regulations and you can take them as carry-on but it's best to check with your airline and let them know. Singapore Airlines was fine with it.<br></div><div>3. Consider buying a hard case for your dry-shipper particularly if you are of Middle-Eastern appearance as much as I enjoyed having an entire subway train section during Munich's morning rush hour to myself. Might not work as well in let's say NYC and 'Fragile'/'This way up' stickers don't mean much to airport staff. </div><div><br></div><div>Overall, frozen grids are a lot more resilient than I thought. The seal on one of my dry-shippers had been broken and someone had clearly looked inside at some stage in transit. Still no issue, which means that you can refrain from placing a mouse trap on top of your samples as tempting as it is.</div><div><br></div><div>Anyway, good luck!</div><div><br></div><div>cheers</div><div>Mazdak <br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 4 February 2015 at 01:55, Karim benzerara <span dir="ltr"><<a href="mailto:karim.benzerara@impmc.upmc.fr" target="_blank">karim.benzerara@impmc.upmc.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">

<p class="MsoNormal"> </p>
<p class="MsoNormal"><span lang="EN-US">We will
perform x-ray microscopy observations on cryo-samples deposited on TEM grids and
prepared by plunge and freeze (something like 20-30 grids). We will prepare the
samples in Paris and we will send them by FEDEX to Berkeley. Would you
recommend a specific DEWAR that will hold the trip and keep our samples frozen
for several days? What volume should I go for? What brand? We are very new to
this so apologize for the basic question.</span></p>
