Product Options

UL/MET/CE Certifications:
Processing tube size:

OTF-1200X-III-UL series furnaces are configurated to meet UL/CSA standard. The furnaces are long, and split-able three-zone tube furnace with tubes up to 127mm (5") O.D capable of quickly heating up to 1200°C. The multiple zones also enable the user to create different thermal gradients by varying the temperature of three zones. The furnace includes one fused quartz tube, one pair of vacuum sealing flanges with pressure gauge & ball valve for immediate use. Three 30 segments temperature controllers are installed with a K-type thermal couple. Microprocessor-based self-tuning PID control provides excellent temperature control without overshooting along with an accuracy of +/- 1 °C. It is an excellent furnace for annealing, diffusing and sintering samples under various gas atmospheres.

Furnace Structure
  • Double layer steel case with two cooling fans, which ensure low surface temperature;
  • Energy saving high purity fibrous alumina insulation;
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  • Quartz block (Optional) is ideal for more cleanness and higher achievable vacuum.
