Some of laboratory processes where atmosphere control is vital, require a tube furnace to be used. Alser AS manufactures tube furnaces of various tube diameters and heated lengths. Through application of Kanthal wire and silicon carbide heating elements the temperature range extends to 1600°C as operation temperature. The work tube is always price inclusive and is either Mullite or Recrystallized Alumina. Outer case has an attactive epoxy powder paint and the outer mesh cover maintains a cooler skin for maximum operator safety. Available in the horizontal or vertical models. Optional consumables include gas tight end fittings of NiCr Steel for controlled atmospheres and vacum applications. Heat shields are provided to minimise heat loss at high temperatures.
