EPS series

Cost-effective in-line preparation stages

The EPS is a cost-effective in-line preparation stage for 2" & 4" substrate preparation. It offers high uniformity heating to 800°C with substrate rotation, height adjustment and shutter options.

How it works

The EPS series of in-line preparation stages supports the substrate parallel to the mounting flange. Crucially, the stationary EPS heating module provides durable and uniform heating of 2" or 4" substrates up to 800°C. It includes Molybdenum heat shields in order to minimise heat loss. What’s more, a Type K thermocouple is provided as standard.

Manual or motorised substrate rotation to 60rpm is possible via the magnetically-coupled MagiDrive rotary drives. Eliminating unnecessary bellows and dynamic seals from the EPS ensures true UHV performance and increased reliability.

In addition to substrate rotation, the 50mm height adjustment option allows the substrate position to be optimised via manual or motorised actuation. The EPS series of preparation stages provide cost-effective and durable sample preparation capability. See the EC-I series for higher temperature heating, DC/RF biasing or additional capabilities.
