The Carbolite Gero MTF 12/38/850 is a bench-mounted, single-zone horizontal tube furnace precision-engineered to provide a simple, highly economical, and efficient solution for general-purpose thermal processing, extended materials synthesis, and calcination routines within laboratory environments. Reaching a maximum operating temperature of 1200 °C, this model stands out as the longest variant in the MTF series, featuring a substantial 850 mm heated length. It incorporates 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 and exceptional heat distribution.
The extended heating profile of the MTF 12/38/850 offers excellent versatility for advanced research projects or high-volume batch processing. 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 ceramic 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.
Economical Extended Architecture: Designed with heating wire wrapped directly around an extended fixed internal ceramic tube, maximizing batch capacity while eliminating accessory costs for standard processing.
Superior Thermal Efficiency: Direct-contact element configuration combined with premium insulation results in optimized heat transfer and a large, stable uniform temperature zone.
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 900 mm horizontal furnace body is stacked neatly above the integrated power and control enclosure, providing a compact, space-saving layout for busy laboratory work surfaces.
