[3dem] Coolant Container of FEI Vitrobot

[Tillmann Pape]

Dear all,

I would like to enquire within the community about their experience  
with the black plastic coolant container of the FEI Vitrobot.

We (with a Vitrobot Model Mark III) have not very good experience  
concerning their lifetime. Again and again we experience very quickly  
some initial cracks upon cooling that grow quite quickly within a few  
months to a sizeable leak of liquid N2, making the whole device not  
very user-friendly anymore and as well a bit of an safety hazard,  
especially for less experienced users. Moreover, the replacement  
prize is quite high.

I was wondering if anybody has had similar experiences and I am  
curious of how they have dealt with this situation.

Many thanks in advance for your feedback.

Kind wishes,

Tillmann
