1400°C Muffle Furnace

Product Description

The BR-14S series 1400°C muffle furnace bridges the gap between general-purpose laboratory box furnaces and specialist high-temperature equipment. With a maximum temperature of 1400°C and a recommended working temperature of 1300°C, this chamber furnace handles a broad range of advanced ceramic sintering, refractory material testing, metal powder processing, and thermal analysis applications that exceed the capability of standard 1200°C equipment.

Fitted with silicon carbide (SiC) rod heating elements and S-type thermocouple temperature measurement, the BR-14S delivers excellent temperature uniformity and long element service life even under continuous high-temperature operation. The polycrystalline mullite fiber lining and reinforced furnace roof construction ensure structural integrity over extended duty cycles.

Product Highlights

SiC Rod Heating Elements Silicon carbide heating elements provide reliable, high-watt-density heating to 1400°C with good oxidation resistance. Suitable for both oxidizing and mildly reducing atmospheres, offering greater versatility than resistance wire elements.

S-Type Thermocouple for Accurate High-Temperature Measurement S-type (platinum-rhodium) thermocouple ensures precise temperature measurement at elevated temperatures, with better stability and accuracy than K-type sensors at the 1300–1400°C range.

50-Segment PID Programmable Control Supports complex sintering and firing profiles with up to 50 programmable ramp-and-soak segments, overheat alarm, and PID auto-tuning.

Scalable Chamber Sizes: 1 L to 1000 L Available across 14 standard sizes from 1 L bench-top models to 1000 L industrial-scale chamber furnaces, with both single-phase and three-phase power configurations.

Upper or Side Door Options Optional top-loading or side-opening door configurations keep operators away from the heat source during loading and unloading — an important ergonomic and safety consideration for frequent-use laboratory environments.

Applications

Advanced ceramic sintering · Refractory material testing · Metal powder sintering · Electronic component firing · Catalyst preparation · High-temperature thermal analysis · Glass frit development
