This unit has provided excellent results in all types of evaporators throughout the electron microscopy community for many years. A combination of ball-bearing motion in the chuck, gravity and long-arc spring-feed give uniform pressure that ensures a smooth, uniform advance of the carbon rod. This smooth motion allows use of a lower current, with a consequent reduction of radiant heat. Designed to hold 1/8" diameter carbon rods. Includes one package of 10 rods.
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.
A necessary accessory for the Ladd Vacuum Evaporator if you intend to do low temperature work requiring a thermocouple feed-through. The feed through is factory-installed, therefore should be ordered with evaporator.
Keeps bell jar clean to provide accurate observation of specimen throughout evaporation. Short circuiting of electrodes by deposited carbon is greatly reduced, as is cleanup time for the entire bell jar. The shield consists of an annealed Pyrex tube mounted between two aluminum discs supported by arms of the carbon evaporation unit. Pyrex glass tube has a precisely proportioned slot to control the flow of carbon to the specimen. this fire-polished tube can easily be removed for cleaning, and will not crack from heat generated during evaporation. Complete mounting instructions included.
