[3dem] Carbon coater

[Guy SCHOEHN]

Hi again

Following Gina's suggestion, please find below the different answer I 
got so far:
It can may be be useful for other lab.


Answer 1

We bought the Cresington 208C carbon evaporator about a year ago.

http://www.cressington.com/product_208c.html

We are quite happy with the system. It is reliable and easy to operate. 
We also bought the thickness monitor although we do not find it very 
useful. We often trust better our traditional method of folding a piece 
of filter paper to cash a white shadow that does not get cover by 
carbon.

The glow discharge accessory is pretty convenient, fast and easy to 
use. If budget allows I would recommend to purchase the system with the 
dry vacuum pumping system comprised of the turbo pump and a Dry Scroll 
Pump. It will make your system completely oil free and will prevent oil 
mist contaminations of your grids.

Answer 2

We also bought the Cressington carbon coater 208 recently and I can 
fully support Joaquins statement. We have it also with the thickness 
monitor but also think that it is not essential to have it. We don't 
have the glow discharge from that company so I can not judge on that.

Answer 3

we have many happy customers using the EMS 150 Series of Coaters. It is 
a very modern and flexible instrument for a good value. You can buy it 
as a rotary- or turbo-pumped system, with carbon-rod and/or carbon-fiber 
source. It is possible to upgrade it with Sputter-, Evaporation-, 
Aperture-Cleaning- and Glow-Discharge inserts. It always uses the same 
base system, vacuum and control unit, therefore it is very flexible and 
favorable.

What would you like to coat? - For high-purity carbon, as used for 
coating grids, the turbo-pumped, high-vacuum system is a must. We 
recommend using a good two to four stage membrane pump as roughing pump. 
It is clean, silent, basically maintainance-free, very reliable and cost 
efficient. Coating just for conductivity is not a big issue and a rotary 
pumped system can be used.

I am happy to help if you have any detailed questions.
