1200℃ Split Tube Furnace with Quartz Tube Laboratory Tubular Furnace

Introduction

The 1200℃ Split Tube Furnace with Quartz Tube is a high-temperature laboratory equipment designed for precise heat treatment in inert atmospheres. Featuring a programmable temperature controller with 30 segments, it supports heating and cooling rates up to 15°C per minute. Suitable for temperatures up to 1200°C, this furnace includes a vacuum pump and accessories like alumina ceramic end plugs for uniform temperature distribution. Ideal for research and testing requiring controlled environments and high temperatures.

Applications

• The 1200℃ Split Quartz Tube Furnace is a dedicated laboratory instrument optimized for precision atmosphere-controlled experiments at ≤1200℃, leveraging high-purity chemically inert quartz tubes and user-friendly split-type configurations. Its core applications include:
• Advanced Nanomaterial Synthesis
• As a simplified CVD platform, it enables fabrication of carbon nanotubes, graphene nanosheets, boron nitride nanobelts, and high-purity metal oxide nanoparticles; also supports calcination of lithium battery cathode materials (e.g., lithium iron phosphate) and ceramic powder crystallization.
• Material Heat Treatment & Interface Modification
• Facilitates solution/aging treatment of Cu/Al alloys, stress-relief annealing of metal wires/sheets, and presintering of ceramic matrix composites. Atmosphere control prevents sample oxidation during thermal processes.
• Semiconductor & Electronic Material R&D
• Ideal for low-temperature boron/phosphorus doping and annealing of Si/Ge wafers, as well as co-firing of electronic ceramics (thermistors, MLCCs). Low impurity release from quartz tubes ensures wafer and component purity.
• Catalysis & Chemical Experiments
• Supports calcination/activation of molecular sieves and supported catalysts (e.g., Pt/Al₂O₃), and small-scale gas-phase catalytic reactions (CO oxidation, VOCs degradation). Corrosion-resistant quartz tubes avoid interference with catalytic processes.
• Academic & Fundamental Research
• A standard tool for material phase transition testing, high-temperature property characterization, and atmosphere-temperature coupling mechanism studies in universities and research institutions.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
