Hi, It occurred to me that I should have reached back out to the list as the questions are not uncommon. With highest regards, Craig Craig S.

They also can tell you about the Cressington carbon coater, though they currently don't have a link on our website. We use a Cressington carbon rod coater for instances were coating thickness is not critical. For FESEM and TEM work, and any instances where coating thickness needs to be uniform and of known thickness nothing beats the ACE600. Our analytical services group has two of these. They work extremely well. You can buy them with a carbon yarn evaporation head and a metal sputter head. Both heads are installed, such that you can create recipes to coat with just one or create layered coatings, without removing the sample. https://www.leica-microsystems.com/products/sample-preparation-for-electron-microscopy/p/leica-em-ace600/ With highest regards, Craig Craig S.

We replaced the rod holder during the summer, and it's already oval. Did any of you have similar issues? If yes, what did you do to fix them? We are also considering buying a new device, as the coater is used daily. Any advice on C coater that can handle heavy usage?
