Product SummaryLabotemp Tube Furnace FMT-18 is a precision horizontal tubular furnace for ultra-high-temperature processing up to 1700°C (working ≤1550°C). It features an ∮80 mm corundum tube, a 440 mm standard heating zone, 1200 mm total tube length and an 80×440 mm chamber. MoSi₂ heating rods, B-type thermocouple, PID control and 30-segment programmable profiling provide ±1°C accuracy and ±5°C uniformity with 0–20°C/min heating ramps. The chamber is insulated with alumina ceramic-fiber.
