[3dem] Carbon evaporator for SPA

[Marion Decossas]

Hello marion,
we have the safematic at the institute, very easy to use with turbo dry 
pump and quartz crystal for thickness measurement. We use it routinely 
for 2nm carbon by evaporation on mica to make a continuous film on the 
grids for the SPA and are very satisfied. Also Safematic's circular 
chamber system is esay to clean and it has an automatic carbon wick 
unwinding really convenient and reproducible.

I'll leave you a small attachment on this machine.

best
