KSL-1700X-HL Compact Hybrid Furnace with Dual 13mm ID Alumina Tubes and Two-Layer Box, 800°C to 1700°C
The KSL-1700X-HL is engineered to address the needs of material research laboratories requiring precise high-temperature processing of multiple small samples in a single run. Its compact design incorporates a high-purity fibrous alumina chamber measuring 120 mm cubed, divided into two layers by a ceramic plate, allowing simultaneous sintering in air or controlled atmospheres.
This hybrid furnace integrates two premier-grade corundum alumina tubes, each with a 13 mm inner diameter and 600 mm length, enabling atmosphere-controlled treatments. The system supports continuous operation up to 1600°C and short-term peaks to 1700°C, with stable and uniform temperature distribution ensured by MoSi2 heating elements and a B-type thermocouple.
Wichtigste Merkmale
- Dual 13 mm ID alumina tubes installed for atmosphere-controlled processing with sealing flanges and vacuum gauge.
- Two-layer sintering box design with 50 mm height per layer for multi-sample processing in air.
- High-purity 1800-grade fibrous alumina chamber with reflective coating for energy efficiency.
- Maximum continuous temperature of 1600°C and peak temperature of 1700°C for up to one hour.
- PID temperature controller with auto-tune, 30 programmable segments, and ±1°C control accuracy.
- Heating rate adjustable up to 20°C/min; recommended ≤10°C/min for temperatures below 1400°C.
- Steel structure with air cooling fan to maintain external case temperature below 60°C.

Typische Anwendungsbereiche
Ideal for sintering and heat treatment of small material samples in research laboratories, including ceramics, metals, and composites. Suitable for experiments requiring controlled atmospheres or air processing with multi-sample throughput.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes four ceramic tube blocks to reduce heat radiation inside the alumina tubes; these must be fully inserted before heating. One pair of sealing flanges with double silicone high-temperature O-rings is provided for atmosphere sealing. Two stainless steel needle valves and a dial vacuum gauge are installed on each tube flange for atmosphere control.
Vacuum pumps are not included and must be ordered separately. The recommended heating and cooling rates are ≤10°C/min to preserve furnace longevity. The furnace is not vacuum-sealed and should not be used with toxic or explosive gases without proper safety measures. Minor refractory ceramic surface cracks may develop with use and can be repaired with alumina coating.
