Model STF55346C Shown with optional process tube and universal end seal.

Three Zone 1100°C Tube Furnaces have new, energy efficient designs incorporating Lindberg/Blue M exclusive Moldatherm® ceramic fiber insulation. Performance attributes include excellent temperature uniformity, fast heat-up and cool-down, and quick recovery with optimum power consumption. The furnace includes three independent, programmable controllers, one for each zone.

General Features

• Innovative use of venting and insulating air spaces to create lower exterior surface temperatures
• Accepts an array of tube adapters (see chart on specifications page)
• Flexible design, may be used for a variety of applications
• One set of (2) tube adapters included standard
