CTF 17/18 Series / PVT Series, High Temp. Horizontal/Vertical Tube
Furnaces , 1700°C & 1800°C
CTF 17/75/300/3216P1
Designed for high temperature
applications utilizing high temperature
RCA (recrystallized alumina) worktubes.
Vertical elements heat an horizontal
tube.
Requires but does not include an
appropriate RCA (recrystallized alumina)
accessory worktube 19.5mm to 90mm
maximum outer diameter.
Continuous operating temperature is 100°C below maximum temperature.
Holding power is measured at the continuous operating temperature.
Uniform length measured with end plugs fitted.
