Hi We are inetrested in buying a vacuum oven which could to a pressure range of few torr or less and can go up to temperatures of 400-500C. Also, we want it to have a mechanical feedthrough to be able to apply pressure . We want to put a device inside, cover it and seal using glass frits. the high temperature is required for firing of glass frits. Kindly suggest if such oven would be available off-the-shelf or if we could get it custom made from somewhere. Thanks, Anshu mehta Yahoo!
