1750°C High Temperature Benchtop Vacuum Atmosphere Tube Furnace with Kanthal Super 1800 Heating Elements and 60mm Alumina Processing Tube

Product Overview

This high-temperature bench-top thermal processing system is engineered to provide a robust and precise environment for advanced material synthesis and chemical research. Capable of reaching sustained temperatures up to 1750°C, the equipment combines a compact footprint with industrial-grade heating capabilities. It serves as a cornerstone for laboratory environments requiring extreme heat within a controlled atmosphere or vacuum, ensuring that sensitive samples are processed without contamination. By utilizing premium Swedish heating elements and USA-made alumina tubing, the system delivers the consistency required for repeatable R&D outcomes in demanding material science applications.

Designed for versatility, this system is widely adopted in chemical research labs and material engineering departments for sintering new material samples. Whether operating under a high vacuum or specific inert gas conditions, the equipment maintains structural integrity and thermal uniformity. The core value proposition lies in its ability to facilitate complex thermal cycles—such as annealing, sintering, and purification—within a single, bench-top unit. This makes it an essential tool for researchers focused on ceramics, metallurgy, and semiconductor development where precision and atmosphere control are non-negotiable.

Confidence in this equipment is built through its rigorous engineering standards, featuring a double-layer steel casing and advanced digital control. The system is designed for longevity and operator safety, maintaining a cool exterior even during peak operation. With CE certification and the option for NRTL or CSA compliance, it meets the stringent safety requirements of international research institutions. Professionals can rely on this unit for continuous performance at 1700°C, backed by a high-precision SCR control system that protects both the heating elements and the delicate samples being processed.

Key Features

• Kanthal Super-1800 Grade MoSi2 Heating Elements: Equipped with 8 pieces of high-performance heating elements made in Sweden, this system ensures rapid heating and exceptional longevity even when operating near its 1750°C limit.
• High-Precision SCR Digital Controller: Utilizing a Silicon Controlled Rectifier with phase angle firing and current limiting resistors, the unit provides significantly more accurate temperature management than standard solid-state relays, maintaining a precision of ±1°C.
• 30-Segment Programmable Thermal Profiling: The advanced PID controller allows for the programming of up to 30 segments, giving researchers total control over heating rates, cooling rates, and dwell times for complex thermal recipes.
• Superior Atmosphere and Vacuum Integrity: Featuring stainless steel vacuum sealing flanges with double silicone high-temperature O-rings, the system can achieve vacuum levels down to 50 mTorr with a mechanical pump and 10^-5 Torr with a turbo molecular pump.
