Tube Furnace Atmosphere Retorts

Blue M® 59400 tube furnace atmosphere retorts are ideal for a wide range of controlled atmosphere processes. Designed for use with Blue M tube furnace and control console systems, these retorts provide maximum operational convenience, reliability and process repeatability.

Unique construction allows maximum heated chamber size for Blue M tube furnaces. High temperature alloy provides for maximum continuous use temperature of 1050°C (1994°F). O-ring seal embedded in a machined groove allows positive seal between door plug and retort top plate. Toggle clamps for positive plug seal and fast opening. Custom designed retorts are available for individual applications.

These versatile retorts are available in both single and double-ended models. The single-ended retorts come equipped with one removable insulated end plug and have the opposite end plugged with an atmosphere outlet pipe. These retorts can be used in both solid and hinged type tube furnaces.

Double-ended models are equipped with two removable insulated end plugs and are designed for use only in hinged type tube furnaces. All retorts are designed so that removable insulated end plugs extend from furnace ends to insure the longest possible seal life.

End plugs of larger retorts (3-inch OD and larger) are provided with an atmosphere inlet and outlet tube and one thermocouple port each. End plugs for smaller retorts (2-inch OD and smaller) are equipped with an inlet and outlet tube.
