[Histonet] Leica Cryostat Service Recommendations

[Connolly, Brett M]

I'll second that, we have 4 of these (all > 6 yrs. old) and are very
happy with them.
We do not have service contracts and, when needed, have a local company
come in for repairs and PMs.

Good tip Emily about the object cooling compressor, thanks!

We have the same cryostat, three years old and this is the first time
anything has broken on it.  The total cost for everything will be about
$600
which is waaaay cheaper than a $4000 service contract (for one year!).
Also we use our cryostat almost every day, all day.  If you're using it
that
little, and it's working fine, I would say hold off on the service
contract.  Just keep it clean and if it stops working, turn it off and
let
it defrost for a few days.  Usually that fixes everything because it's
just
iced over somewhere.
Leica service contracts are a complete waste of money--only get them if
you
need to spend money (which was the case for us a few years ago,
unfortunately, it's not now!).
Also, don't get Leica to fix your cryostat! They charge twice as much as
anyone else.
One thing to remember to save your object cooling compressor motor, when
you
restart your cryostat after defrosting, cool the chamber first, then
specimen head.  That way, the specimen head (object temperature)
compressor
will not have to work as hard to keep itself cool while the chamber is
cooling.

A great book should leave you with many experiences, and slightly
exhausted.
You should live several lives while reading it.
