The RD-G is a high temperature vacuum/inert gas furnace designed
specifically for university, industrial, and government research laboratories.
Both installation and operation are simple and inexpensive. No cooling water
or drain is required and a standard wall outlet provides sufficient electrical
power to operate the furnace at full temperature. There are no water cooling
channels to clog, no chamber corrosion from galvanic action, and no water
leaks degrading vacuum quality.
