Laboratory Muffle Furnaces

Yamato Scientific muffle furnaces deliver clean, high-temperature heating to 1150°C for ashing, sintering, calcination, heat treatment, and materials testing. LabSupplies.com is an authorized Yamato dealer offering the full range — from compact 1.5 L benchtop units to 30 L chamber furnaces, in both communication-port (FO) and high-precision (FP) series. Every model ships from USA inventory.

Two Yamato muffle furnace series

• FO series — communication-port furnaces (1.5–30 L) — eight chamber sizes with an RS-485 communication port for data logging and system integration, ceramic-fiber insulation, and ±2°C accuracy at 1150°C. The workhorse range for ashing and routine high-temperature work.
• FP series — high-performance furnaces (1.5–11.3 L) — tighter ±1.0°C accuracy with alumina-fiber insulation, advanced programmable control (up to 99 steps), and power/CO₂ monitoring for demanding, repeatable heat-treatment protocols.

Key selection criteria

• Temperature ceiling — both series reach 1150°C; confirm headroom above your process temperature.
• Precision — ±2°C (FO) for general work, ±1.0°C (FP) for tight-tolerance heat treatment.
• Chamber capacity — 1.5 L benchtop to 30 L; size to your crucible or sample batch.
• Programmability — multi-step ramp/soak profiles for staged heating and controlled cooling.
• Integration — the FO series adds a communication port for data logging and automation.
• Power — heater wattage and circuit scale with chamber size; verify facility supply.
