[3dem] cryo TEM holder for autogrids and ThermoFisher/FEI

[Israel Fernandez]

Hi,
I have some experience with the ELSA holder but not the configuration
compatible with autogrids but the "classical" pinned washer on top of the
grid. The holder was used in a F20 with a K2 and it behaved really well. It
took some time to readjust yourself to the large liquid nitrogen tank that
forces you to have a peculiar grab on it  but after some vacuum crashes you
find a way to get it in nicely. After one hour or so with the holder in,
you can collect 6-8 hours without refilling and most importantly, with
minimal drift for a side entry instrument. I also liked the simple and
straightforward system to warm the holder up and run the baking cycle.
Overall, great experience.
