High Performance Muffle Furnace 11.3L Overview
The High Performance Muffle Furnace 11.3L (model FP413) from Yamato Scientific is a microprocessor-controlled muffle furnace delivering an operating range of 100 to 1150°C across an 11.3 L chamber. LabSupplies.com, an authorized dealer, supplies the genuine unit for ashing, sintering, heat treatment, and high-temperature materials testing.
Construction pairs an alumina-fiber interior with a cold-rolled steel exterior finished in baked melamine resin. A firmly sealed chamber door improves heat tightness, while the alumina porcelain hot plate keeps the 3.25 kW iron-chrome heater from contacting the chamber to prevent sample contamination. R-thermocouple sensing holds accuracy to ±1.0°C at 1150°C.
Power requirement is 220V, and the furnace ships at roughly 200 lbs with a 36 × 36 × 35 in crated footprint. Manufactured in Japan, this model carries ISO 9001:2015 and ISO 14001:2015 certifications. Program operation supports up to 99 steps across 99 patterns with a repeat function for reproducible thermal profiles.
Key Features
- PID microprocessor control: regulates temperature with excellent repeatability and high visibility for precise high-temperature work.
- ±1.0°C accuracy: tight temperature control at 1150°C, with ±4.0°C distribution and a 14°C gradient across the chamber.
- R-thermocouple sensing: upgraded long-life sensor supports stable readings throughout the 100 to 1150°C range.
- Contamination-resistant hot plate: alumina porcelain construction shields the iron-chrome 3.25 kW heater from the inner chamber, protecting samples.
- Programmable operation: up to 99 steps and 99 patterns with repeat function, plus fixed-temperature and auto start/stop modes.
- Layered safety system: self-diagnostics, key lock, independent overheat prevention, automatic overheat prevention, and electric leakage breaker.
How to Choose the Right Muffle Furnace
Matching a muffle furnace to your workflow means weighing chamber size, peak temperature, control sophistication, and site power. Use these axes to confirm the FP413 fits your application before ordering.
- Capacity: the 11.3 L chamber (300 × 250 × 150 mm interior) determines crucible count and batch size, so verify it accommodates your largest routine load.
- Temperature range: a 100 to 1150°C span suits ashing, sintering, and heat treatment; confirm your process never exceeds the upper limit.
- Control type: PID microprocessor control with 99-step programming benefits multi-stage ramp-and-soak protocols versus single-setpoint work.
- Voltage and power: 220V and a 3.25 kW heater require a dedicated circuit, so check your bench power before installation.
- Footprint and weight: a 200 lb unit with a 36 × 36 × 35 in crated size needs adequate bench space and a clearance plan.
- Safety requirements: independent overheat prevention and a leakage breaker matter for unattended or overnight runs.

Frequently Asked Questions
What temperature range does the FP413 muffle furnace operate across?
The FP413 operates from 100 to 1150°C. R-thermocouple sensing and PID microprocessor control hold accuracy to ±1.0°C at 1150°C, with ±4.0°C distribution and a 14°C gradient across the chamber.
What is the chamber capacity and interior size?
Chamber capacity is 11.3 L, with interior dimensions of 300 × 250 × 150 mm. That volume suits crucible-based ashing, sintering, and heat-treatment batches.
What voltage and power does the FP413 require?
The FP413 runs on 220V and uses a 3.25 kW iron-chrome wire heater. Provide a dedicated circuit sized to the heater load before installation.
How does the furnace protect samples from contamination?
An alumina porcelain hot plate keeps the heater from being exposed to the inner chamber, preventing sample contamination. The interior uses alumina fiber, and a sealed chamber door improves heat tightness.
Can the FP413 run multi-stage temperature programs?
Yes. Program operation supports up to 99 steps and 99 patterns with a repeat function. Fixed-temperature, quick auto-stop, and auto start/stop modes are also available.
What safety features are built into the FP413?
The FP413 includes self-diagnostic functions, a key lock, independent overheat prevention, automatic overheat prevention, and an electric leakage breaker. Self-diagnostics cover sensor error, heater disconnection, triac short-circuit, and main relay failure.
