PTF Series Tube Furnaces

LABTHERM PTF series tube furnaces are tube furnaces that could be used when laboratory experimentation is performed horizontally, vertically, or at specific angles. Configuration of the tilt angle, and the stable temperature environment make these furnaces suitable for many possible processes. Standard PTF series furnaces cover a range from 1100°C to 1600°C, using wire and SiC heating elements for processes. SiC heating rods installed parallel to the working tube ensuring perfect temperature uniformity and easy replacement. PTF series are tube furnaces, suitable for heat treatment processes that are performed horizontally, vertically or at specific angles with controlled atmospheric conditions. Wire heating element is wounded directly onto the fixed ceramic tube to maintain excellent temperature uniformity within the tube. The stable heated length and the standard tube dimensions applicable to create vacuum or inert gas environment, make these furnaces suitable for many laboratory tests.
