KSL1200XMF Muffle Furnace with 310S Alloy Chamber, 1100°C Max Temperature for Debinding and Inert Gas Sintering
The KSL1200XMF muffle furnace is engineered for laboratory processes requiring controlled thermal treatment, such as debinding of porous materials and sintering under inert atmospheres. Its internal 310S alloy refractory chamber enables the removal of binders or glues by allowing gas flow through dedicated inlet and outlet ports, facilitating the preparation of samples sensitive to oxidation or contamination.
This furnace features a spacious heating chamber measuring 12″ x 12″ x 12″ (304 x 304 x 304 mm) with a 9″ x 9″ x 10″ (230 x 230 x 250 mm) alloy chamber inside. The alloy chamber is not airtight but effectively contains fumes to protect the heating elements. For air-sensitive materials, an inert gas mixture such as 5% H2 with 95% Ar is recommended to prevent oxidation during thermal processing.
Key Features
- Heating chamber capacity of 27 liters with three-sided Ni-Cr-Al wire heating elements embedded in high-purity fibrous alumina.
- 310S alloy refractory chamber with hinged door, gas inlet and outlet tubes (8 mm ID) for controlled atmosphere processing.
- Maximum operating temperature of 1100°C with alloy chamber installed; up to 1200°C without it.
- PID temperature controller with auto-tune, 30 programmable segments, and ±1°C stability for precise thermal profiles.
- Separate temperature controller housing for enhanced operator safety.
- Includes K-type thermocouple inside the alloy chamber for accurate temperature monitoring.
- CE certified with optional NRTL (UL61010) or CSA certification available.

Typical Applications
Ideal for debinding processes where removal of organic binders is required without contaminating the heating elements. Suitable for sintering oxygen-sensitive materials under controlled inert gas atmospheres to prevent oxidation. Also applicable in materials research and development requiring precise thermal profiles and atmosphere control.
Configuration & Operating Notes
The furnace includes a separate programmable temperature controller with PC communication capability and software for advanced temperature profiling. The power cable is supplied without a plug; users must install a suitable plug according to local electrical codes. While the alloy chamber is not airtight, it effectively limits fumes to protect the furnace. For air-sensitive samples, use an inert gas mixture such as 5% hydrogen in argon to minimize oxidation risks. Optional Eurotherm controllers with higher accuracy are available at additional cost. CE certification is standard; NRTL or CSA certifications can be requested.
