DV-502B High Vacuum Evaporator

The DV-502B is the newest addition to the proven line of DV-502 series of evaporators. Since 1964, thousands of these units have been installed at universities and research labs throughout the world.

By using state-of-the-art electronic components and an advanced vacuum design, the DV-502B can rapidly and repeatedly cycle from atmosphere to high vacuum .

Pumping Performance

The DV-502B will reach 10 -4 Torr in a clean and outgassed system within 3 minutes, and 2 x 10 -5 Torr within 4 minutes in the standard 12” dia. X 12” high bell jar. No discernible contamination is produced in preparing specimens for electron microscopy.

The 1 kVA evaporation power supply permits evaporation of most materials used in electron microscope specimen preparation including carbon, gold, gold palladium, platinum, etc., and can handle many of the evaporations required in various metalizing, optical coating and other applications. The DV-502B has sufficient pumping speed to handle all of the standard Denton accessories as well as larger bell jars up to 12” dia. X 18” high.
