Tungsten Basket Evaporation Shields - A shield greatly reduces deposits of evaporated metals on the electrodes and bell jar, yet allows clear observation of the amount on the specimen. Special features of each unit are:
     Two side arms which fit filament posts, each supporting a chrome-plated disc.
     An annealed Pyrex tube which slides over the discs and is held securely
in place by a coiled spring.      
     A precisely sized slot in the tube, which aligns accurately with a hole in the metal shield held in place beneath the slot, allowing controlled passage of evaporated metal to specimens.
     Pyrex tube and metal shield can be rotated, permitting coating or shadowing from any angle.
     P yrex tubing will not crack from heat generated during evaporation.
     Complete instructions included with each unit.
