1500C Two Zone Split Tube Furnace with Vacuum Flange and 80mm Alumina Tube

Product Overview

This high-temperature thermal processing system represents a pinnacle of engineering for laboratories and industrial research facilities requiring precise atmospheric and temperature control. Designed as a dual-zone split tube configuration, the equipment provides an versatile platform for advanced material synthesis, chemical vapor deposition (CVD), and complex sintering processes. By utilizing a split-hinge architecture, the unit allows for effortless access to the reaction chamber, facilitating the rapid exchange of processing tubes and accommodating complex experimental setups that involve pre-assembled components or delicate sample positioning. Its core value proposition lies in its ability to maintain high-stability thermal environments up to 1500°C, supported by robust silicon carbide heating technology.

The system is engineered to serve critical roles in metallurgy, semiconductor development, and aerospace material testing. It delivers exceptional flexibility, enabling users to transition between vacuum-sealed environments and controlled gas atmospheres with minimal downtime. The dual-zone configuration allows for the creation of sophisticated thermal gradients or the maintenance of extended uniform temperature zones, depending on the specific requirements of the heat treatment cycle. This unit's adaptability makes it a foundational tool for researchers pushing the boundaries of high-temperature chemistry and physics under rigorous, repeatable conditions.

Reliability is at the heart of this furnace's design. Utilizing premium grade S-type thermocouples and advanced PID instrumentation, the equipment ensures consistent performance even during prolonged continuous operation at 1400°C. The robust stainless steel vacuum sealing flanges and high-purity alumina processing tubes are selected for their durability and resistance to thermal shock, ensuring a long service life in demanding R&D environments. Every component is meticulously integrated to provide a stable, safe, and highly controllable thermal environment that meets the exacting standards of modern industrial procurement teams and material scientists.

Key Features
