60975 - Dual Shielded Double Source Evaporation Unit

Designed specifically for use in scanning electron microscopy. Consists of a heavy nickel plated brass base with securely positioned two sets of upright posts. One set of posts has an extension attachment to hold a carbon evaporation source and the other set holds tungsten basket for metal evaporation. Both sources are shielded by a single annealed Pyrex tube with a carefully proportioned slot in the bottom to enable evaporated material to flow to the specimen. Carbon and metal can be evaporated during a single pump-down. Keeps bell jar clean to allow accurate observation of entire process, and saves clean up time.
