[3dem] Turbo-Pumped Carbon Coater

[Joaquin Ortega]

Dear Sara,

We recently purchased the 208C High Vacuum Turbo Carbon Coater from Cressington (commercialized by Ted Pella in North America)

http://www.tedpella.com/cressing_html/cres208C.html

We use it to prepare thin carbon films for grids that we use in negative staining and cryo-EM in single particle applications. The system has an optional glow discharge attachment. We purchased this attachment but it is back ordered and we have not installed yet, so I cannot comment on that. However, we are pretty happy with the quality of the carbon films produced by the unit. 

It is also possible to buy a thickness monitor for this unit, which we purchased but I do not find it very accurate or reliable. One down side was that one of the boards of the unit broke only after a couple of weeks of using it. Ted Pella was pretty fast in replacing it and it was covered under the warranty. They mentioned that it was a 'common' problem in this unit. We did not have any other problems after that. Also if you are in a rush to get the coater in your lab, for this unit it takes about three months for delivery.

Best regards,

Joaquin
