OTF-1200X-80-SL Sliding Tube Furnace with 1200°C Max Temperature, 80mm OD Quartz Tube, and Rapid Heating/Cooling via Sliding Rails
The OTF-1200X-80-SL is engineered for laboratory applications requiring rapid thermal cycling and precise temperature control within a controlled atmosphere. It incorporates a high purity fused quartz processing tube with an 80 mm outer diameter and 75 mm inner diameter, extending 1400 mm in length, suitable for accommodating various sample sizes and experimental setups. The furnace achieves a maximum temperature of 1200°C for short durations and maintains continuous operation up to 1100°C.
A distinctive feature of this model is its sliding mechanism, consisting of a pair of chromium-plated steel rails approximately 1200 mm in length, allowing the furnace body to be manually shifted laterally by up to 600 mm. This design facilitates rapid heating and cooling cycles by preheating one side of the tube and sliding the furnace to the sample position or away from it, enabling heating and cooling rates up to 15°C per second under vacuum or inert gas conditions. This approach minimizes thermal lag and enhances throughput for thermal processing tasks.

대표적인 적용 분야
This furnace is ideal for rapid thermal processing tasks such as annealing, sintering, and material synthesis under vacuum or inert atmospheres. Its sliding design supports fast thermal cycling for research in semiconductor fabrication, ceramic processing, and thin film deposition studies.
구성 및 작동 안내
The furnace includes two foam ceramic blocks to protect O-rings from heat radiation inside the quartz tube. A digital vacuum gauge and needle valve are installed on the flanges for immediate vacuum use; however, vacuum pumps and certain flange accessories (bellows, KF25 adapters, clamps) are not included and must be sourced separately. The sliding rails feature a clamp to secure the furnace position during operation.
Users should install a two-stage pressure regulator on gas cylinders to limit pressure below 3 PSI for safe operation. Gas flow rates should be kept under 200 SCCM to minimize thermal shock to the quartz tube. Fast cooling by sliding the furnace away requires appropriate heat-resistant protective equipment. The included PC control module and temperature calibrator enable detailed temperature profiling and data logging.
