Digital High Vacuum Accessories - Bell Jars & Evaporation Equipment

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.

Dark green #5 lens protects the eyes while observing evaporation of metals and carbon. Fit over most prescription glasses. No-fog vents. Adjustable headband. NOW with free #10 lens.
