Labotemp Muffle Furnace FMU-23 is a compact high-temperature laboratory muffle furnace engineered for precision sintering, ceramic research, metal material testing, and advanced composite processing requiring stable thermal performance up to 1700°C. Built around premium 1800-grade MoSi2 heating rods with excellent high-temperature oxidation resistance, this furnace delivers consistent and clean heat treatment in an 8-litre chamber (200×200×200mm). The high-purity ultra-clean alumina polycrystalline fiber insulation, vacuum-formed for exceptional chemical stability, effectively prevents sample contamination and ensures sintering purity across critical research and industrial workflows.
The dual-carbon shell air-cooled structure with built-in forced convection maintains the furnace surface within room temperature +45°C, ensuring operator safety during continuous high-temperature operation. A 50-segment programmable digital PID intelligent control system paired with precision B-type thermocouples delivers ±1°C temperature accuracy and repeatable thermal profiles for complex research protocols. With 5kW single-phase power supply and optional gas inlet/outlet, exhaust port, touchscreen, and RS485 communication interface, the FMU-23 supports both standard and atmosphere-controlled sintering environments.
