Compact Split Tube Furnace with Insertable Temperature Calibrator and Integrated Vacuum System

Product Overview

This high-performance thermal processing system is engineered for precise material synthesis and heat treatment within a controlled environment. The unit features a split-hinge design that allows for rapid cooling and easy access to the quartz processing tube, making it an ideal choice for laboratories requiring frequent sample turnover or complex experimental setups. By integrating a dedicated vacuum system and an insertable temperature calibrator, the equipment provides a turnkey solution for researchers who demand high-level accuracy and repeatability in their thermal cycles.

The primary use cases for this equipment span across material science, semiconductor research, and industrial R&D. It is specifically designed to handle processes such as annealing, sintering, and chemical vapor deposition under vacuum or flowing gas conditions. The system's ability to maintain a stable environment up to 1200°C ensures it meets the rigorous standards of both academic institutions and industrial metallurgy labs. Its compact footprint allows for seamless integration into existing lab spaces or placement within fume hoods for specialized safety requirements.

Built with a focus on long-term reliability, the system utilizes heavy-duty steel casing and energy-efficient alumina fibrous insulation to ensure structural integrity and thermal efficiency. The inclusion of high-quality Fe-Cr-Al alloy heating elements, doped by Molybdenum, ensures consistent performance even under demanding continuous operation. Procurement teams can trust this unit for its robust engineering and the inclusion of NIST-traceable calibration tools, ensuring that experimental data remains verifiable and consistent across different batches and projects.

Key Features

• Precision Split-Hinge Design: The furnace chamber is constructed with a split-opening mechanism, enabling users to easily install processing tubes and access samples without dismantling the entire setup. This feature also facilitates rapid cooling after high-temperature cycles.
• In-Situ Temperature Calibration: This system includes a specialized OMEGA K-type thermocouple and a portable digital temperature calibrator with a NIST certificate. This allows for real-time, exact measurement of the sample temperature inside the tube, bridging the gap between controller readings and actual specimen conditions.
• Advanced PID Thermal Management: The unit is equipped with a sophisticated PID automatic controller utilizing PWM solid-state relays. It supports 30 programmable segments for heating, dwelling, and cooling, maintaining a tight temperature accuracy of ±1°C.
• High-Efficiency Vacuum Integration: A complete vacuum solution is provided, featuring a 156 L/m double-step rotary vane mechanical pump. This allows the system to reach vacuum levels of 1E-2 Torr (50 m-torr) quickly, supported by stainless steel flanges and a digital vacuum gauge.
• Superior Thermal Insulation: The heating chamber is lined with high-purity Al2O3 fibrous thermal insulation. This energy-efficient material reduces heat loss to the exterior casing, ensuring rapid ramp-up rates and lower energy consumption during long-duration processes.
• Versatile Gas Handling Capabilities: The left flange is equipped with a 1/4'' barb gas inlet, while the right side features a KF25 gas outlet. This configuration allows for precise control of atmosphere-sensitive processes using inert or reactive gases at low flow rates.
• Durable Heating Elements: Engineered with Fe-Cr-Al alloy elements doped with Molybdenum, the furnace provides extended service life and stable resistance at high temperatures, ensuring uniform heat distribution across the 200mm heating zone.
• Enhanced Safety and Monitoring: The system includes comprehensive safety features such as thermal blocks to prevent radiation loss and a heavy-duty steel casing. Optional software interfaces allow for remote data logging and recipe management via a PC.
