Overview
The DRETOP GLK-1210C is a horizontally oriented, programmable tube furnace engineered for precise thermal processing under controlled atmospheric or vacuum conditions. It operates on resistive heating principles using high-stability Ni-Cr alloy elements embedded within a monolithic, vacuum-formed polycrystalline mullite fiber insulation chamber—ensuring exceptional thermal uniformity (±3 °C across the 440 mm hot zone) and energy efficiency. Unlike conventional muffle furnaces, the GLK-1210C integrates dual-sealed KF flanges, side-access gas inlets, and vacuum compatibility down to 1×10⁻³ Pa, enabling reproducible inert, reducing, or vacuum-based thermal treatments critical for materials synthesis, sintering, and surface modification. Its design conforms to ISO 9001-compliant manufacturing protocols and supports GLP-aligned operational traceability when paired with optional data-logging software.
Key Features
- Multi-segment programmable temperature controller (up to 30 segments) supporting ramp-hold-cool profiles with independent rate and setpoint control per segment;
- High-density polycrystalline mullite fiber furnace chamber—low thermal mass, low heat loss (<1.5 kW/h at 1200 °C), and axial temperature uniformity of ±3 °C over 300 mm;
- Horizontally mounted quartz (≥99.99% SiO₂) or alumina (99.7% Al₂O₃) tube with Ø100 × 440 mm internal dimensions—chemically inert, resistant to thermal shock (ΔT > 800 °C), and compatible with rapid quenching;
- KF-25 quick-connect stainless steel flanges with dual elastomeric sealing rings (Viton®/FFKM) ensuring leak rates <1×10⁻⁸ mbar·L/s under vacuum;
- Integrated lid interlock system: automatic power cutoff upon top-lid opening; optional mechanical safety latch compliant with EN 61000-6-2 EMC and IEC 61000-6-4 emission standards;
- Side-access sample loading port with integrated push-pull rod assembly—enabling in-situ handling without breaking vacuum or atmosphere;
- Optional tilt mechanism (±15°) for gravity-assisted powder discharge, volatile byproduct venting, and improved melt flow during MIM/CIM sintering;
- Comprehensive safety suite: Class II insulation, grounded chassis, real-time thermocouple break detection, over-temperature cut-off (settable offset ≥5 °C above target), and residual current device (RCD) protection.
Sample Compatibility & Compliance
The GLK-1210C accommodates cylindrical, granular, and pelletized samples up to Ø90 × 400 mm. It is routinely deployed for ASTM E1111-compliant thermal gravimetric analysis (TGA) pre-treatment, USP glass transition studies, ISO 13320 laser diffraction sample conditioning, and ISO 21368-compliant ceramic sintering validation. The furnace meets CE marking requirements (2014/35/EU Low Voltage Directive and 2014/30/EU EMC Directive), supports 21 CFR Part 11–compliant electronic record retention when used with DRETOP’s optional DataTrace Pro software, and is compatible with ISO/IEC 17025-accredited laboratory quality management systems. All tube materials comply with RoHS 2011/65/EU restrictions on hazardous substances.
Software & Data Management
The standard PID controller includes RS485 Modbus RTU interface for integration into LabVIEW™, MATLAB®, or SCADA environments. Optional DataTrace Pro software provides real-time graphing, CSV export, audit trail logging (user ID, timestamp, parameter changes), and automated report generation aligned with FDA 21 CFR Part 11 Annex 11 expectations. Calibration certificates (traceable to NIST standards) are available for thermocouples (Type S, ±0.5 °C at 1200 °C) and pressure transducers (Pirani gauge, ±5% full scale). Firmware updates are delivered via secure HTTPS portal with SHA-256 signature verification.
Applications
- Thermal treatment of Li-ion battery cathode/anode precursors (e.g., NMC, LFP, silicon-carbon composites) under Ar/N₂/H₂ mixtures;
- CVD precursor pyrolysis and thin-film deposition (e.g., graphene, MoS₂, SiC coatings);
- Metal injection molding (MIM) and ceramic injection molding (CIM) debinding and sintering cycles;
- Carbon fiber oxidation stabilization (200–300 °C in air) and carbonization (800–1200 °C in N₂);
- High-purity semiconductor dopant diffusion (e.g., B, P, As in Si wafers);
- Thermal desorption of organics from catalysts and adsorbents (TDA/TPO protocols);
- Controlled atmosphere annealing of optical fibers and photonic crystals;
- Research-scale synthesis of perovskites, MXenes, and metal–organic frameworks (MOFs).
FAQ
What vacuum level can the GLK-1210C achieve, and what pump compatibility is required?
The system achieves ≤1×10⁻³ Pa using a two-stage rotary vane pump (e.g., Edwards RV8) or a turbomolecular pump for sub-10⁻⁴ Pa applications. KF-25 ports accept standard vacuum accessories including Pirani and cold cathode gauges.
Can the furnace operate continuously at 1200 °C?
Yes—rated for continuous operation at 1200 °C with quartz tube; for extended service life (>2000 h), operation at ≤1100 °C is recommended. Alumina tube option extends max continuous duty to 1300 °C.
Is third-party calibration support available?
DRETOP provides factory calibration certificates (NIST-traceable) and partners with ISO/IEC 17025-accredited labs (e.g., SGS, TÜV Rheinland) for on-site verification.
How is gas flow controlled and monitored during operation?
Standard configuration includes dual needle valves and a mechanical pressure regulator. Optional mass flow controllers (MFCs) with digital display and 4–20 mA output enable closed-loop gas composition control.
Does the furnace meet electromagnetic compatibility (EMC) requirements for use in shared lab environments?
Yes—certified to EN 61326-1:2013 for laboratory equipment, with conducted/radiated emissions below Class B limits and immunity to electrostatic discharge (±8 kV contact, ±15 kV air).
