Overview
The BEQ BTF-1100C-S-D-25 is a compact, single-zone horizontal tube furnace engineered for precision thermal processing of small-volume samples in research laboratories and analytical workflows. Designed around resistive heating via high-stability alloy resistance wire, the furnace operates on standard 220 V AC power and delivers stable, repeatable temperature profiles up to 1100 °C — with a recommended continuous operating limit of 1000 °C to ensure long-term thermal stability and element longevity. Its compact external footprint (280 × 200 × 195 mm) and lightweight construction (12 kg net) enable seamless integration into constrained benchtop environments, including glovebox interfaces, thermogravimetric analysis (TGA) coupling setups, and in situ XRD or mass spectrometry sample introduction modules. The furnace employs a robust ceramic fiber insulation architecture, minimizing thermal mass and enabling rapid, energy-efficient heating cycles — critical for iterative process development and low-power lab infrastructure.
Key Features
- Compact form factor optimized for space-constrained labs and modular instrument integration
- Fuzzy PID temperature controller with auto-tuning capability ensures minimal overshoot and high reproducibility across repeated thermal cycles
- 30-stage programmable ramp-and-soak profile support enables complex thermal protocols (e.g., multi-step calcination, controlled oxidation/reduction, annealing sequences)
- Dual-safety monitoring: real-time over-temperature cutoff and thermocouple break detection with audible/visual alarm output
- Bidirectional RS485 communication interface supports remote parameter setting, real-time data logging, and synchronization with external DAQ systems or LIMS platforms
- Ceramic fiber insulated chamber with low thermal inertia facilitates ≤50 °C/min heating rates while maintaining ±1 °C steady-state control accuracy at 1000 °C
Sample Compatibility & Compliance
The BTF-1100C-S-D-25 accommodates standard quartz or alumina tube configurations (ID ≤25 mm), supporting solid powders, thin films, catalyst pellets, and micro-sized metal/ceramic specimens. Its uniform 160 mm heating zone ensures axial thermal homogeneity suitable for quantitative gravimetric studies when paired with microbalances (e.g., Mettler Toledo XP series) under inert or controlled-atmosphere conditions. While not certified to IEC 61000-6-4 or UL 61010-1 as a standalone system, the furnace complies with general laboratory safety principles per ISO/IEC 17025:2017 Annex A.2.4 for equipment suitability and traceable calibration — requiring end-user verification of thermocouple calibration (Type K or S) against NIST-traceable references prior to GLP/GMP-critical applications.
Software & Data Management
The integrated digital controller provides local HMI operation with intuitive menu navigation and real-time display of setpoint, actual temperature, power output %, and active program stage. For automated data capture, optional Modbus RTU protocol support allows integration with LabVIEW, MATLAB, or Python-based control scripts via standard serial-to-USB adapters. All alarm events, manual overrides, and program execution logs are timestamped and stored in non-volatile memory — supporting audit trails required under FDA 21 CFR Part 11 when deployed in regulated QC/QA environments with appropriate validation documentation.
Applications
- Pre-treatment of electrode materials for battery R&D (e.g., LiCoO₂, NMC cathode precursors)
- Controlled pyrolysis of polymer-derived ceramics and MOF frameworks
- Inert-atmosphere annealing of semiconductor thin films (e.g., ZnO, TiO₂) on Si/SiO₂ substrates
- Thermal desorption calibration standards preparation for GC-MS and PTR-TOF instruments
- Small-batch sintering of dental or biomedical oxide ceramics (e.g., Y-TZP, hydroxyapatite)
- Support heating module for coupled TGA-FTIR or TGA-MS evolved gas analysis systems
FAQ
What tube diameters are compatible with the BTF-1100C-S-D-25?
The furnace is dimensionally optimized for tubes with outer diameters up to 25 mm; standard quartz tubes (OD 25 mm, ID 20 mm, length 600–1000 mm) are routinely used.
Is atmosphere control supported?
Yes — the front and rear flanges accept standard CF-25 or KF-25 vacuum fittings; users may connect gas manifolds for inert (N₂, Ar), reducing (5% H₂/95% N₂), or oxidizing (air, O₂) atmospheres with flow regulation.
Can the controller be calibrated in-house?
The unit accepts user-input offset correction for thermocouple drift; however, full calibration requires a reference thermometer traceable to national metrology institutes (e.g., NIST SRM 1750) and should follow ISO/IEC 17025 procedures.
What maintenance is recommended for long-term reliability?
Annual inspection of resistance wire integrity, ceramic fiber insulation compression, and thermocouple junction condition is advised; avoid thermal shock by limiting ramp rates below 30 °C/min during initial commissioning.
Does this model meet CE or RoHS requirements?
As a domestically manufactured laboratory device intended for OEM integration or research use, formal CE marking is not applied; RoHS-compliant materials are used in PCB and wiring assemblies per manufacturer specification.
