Carbolite Gero MTF 12/38/400 Tube Furnace - 1200°C / 38mm ID

The Carbolite Gero MTF 12/38/400 is a compact, single-zone horizontal tube furnace precision-engineered to provide a simple, highly economical, and efficient solution for general-purpose thermal processing, materials synthesis, and calcination routines within laboratory environments. Reaching a maximum operating temperature of 1200 °C, this model features a built-in, integrated ceramic work tube with the heating wire wound directly around its outer surface. This design eliminates the baseline requirement of purchasing an additional work tube accessory, allowing the furnace to be operated immediately out of the box. This direct-contact configuration guarantees superior thermal transfer efficiency, enabling the internal chamber to hit maximum temperature in an impressive 25 minutes.

Despite its integrated configuration, the MTF 12/38/400 offers excellent versatility for advanced research projects. When applications require a high vacuum or a modified gas atmosphere, a secondary inner work tube (insert tube) can be easily nested within the fixed internal seramic tube. This dual-tube setup provides the extended length necessary to accommodate gas-tight end flanges and vacuum seals, while effectively creating a physical shield that protects the fixed tube and underlying heating coils from corrosive sample outgassing or chemical scaling. Precise single-zone thermal loops are governed by the industry-proven Carbolite Gero 301 digital PID controller, featuring single-ramp control to setpoint, automated delayed start, and integrated process timing as standard.

Product Highlights:

• Economical Integrated Architecture: Designed with heating wire wrapped directly around a fixed internal ceramic tube, minimizing startup costs and accessory requirements for standard processing.

• Ultra-Fast Thermal Response: Direct-contact element configuration combined with premium insulation results in an ultra-fast heat-up rate, reaching maximum temperature in just 25 minutes.

• Dual-Tube Protection System: Supports the insertion of a secondary inner tube to safeguard the core heating infrastructure against chemical contamination, run-away reactions, or sample spillages.

• Atmospheric Control Adaptability: Easily configurable with extended insert tubes, gas-tight end flanging packages, and vacuum accessories for working with modified atmospheres.

• Intuitive Digital PID Controller: Features the Carbolite Gero 301 digital controller as standard, supporting smooth single-ramp heating profiles, digital process timing, and automated delayed start functions.

• Rigid Benchtop Footprint: The horizontal furnace body is stacked neatly above the integrated power and control enclosure, providing a compact, space-saving layout for busy laboratory work surfaces.
