A set of 4 Stainless Steel Vacuum Jackets - For Vacuum and Inert Gas Grinding

The Stainless Steel Vacuum Jacket is designed to realize vacuum or inert gas milling atmosphere for those non steel grinding jars, on which vacuum port and inert gas port can not be made. 

The stainless steel vacuum  jackets work with grinding jars of materials other than stainless steel, such as agate, Tungsten carbide, and zirconia. The agate, Tungsten, or Zirconia can not form a closed chamber, in which the atmosphere (Vacuum or inert gas) is manipulable with help of vacuum valves. 

The Vacuum stainless steel jars can not be used directly to mill materials in vacuum or inert gas environment.
