Thanks to the temperature stability in its ceramic tube, this furnace is the best help you can have for experiments and heat treatment testing of various small charges. You can also move the charge during the heat process without significant temperature drops.
The greatest advantage of the LT furnace is the possibility of stopping up the tube with metal plugs with insulation. Thanks to these, the tube furnace can then have properties similar to a gastight furnace, enabling you to treat charges in them under a protective atmosphere.
