Labozon Muffle Laboratory Furnace (Lab Muffle Furnace) sustains a continuous working temperature of 1300°C in a 5 L chamber with ±1°C accuracy via S-type thermocouple control. Quartz tube heating element protection and dual-layer housing keep the external surface cool while resisting harmful gases. Manufactured for ash analysis, heat treatment, sintering, and melting in high-temperature research and materials laboratories.
