High Performance Muffle Furnace 1.5L Overview
The High Performance Muffle Furnace 1.5L (Yamato Scientific model FP103) is a microprocessor-controlled muffle furnace built for ashing, sintering, and high-temperature material testing across a 100 to 1150°C range. LabSupplies.com supplies this 1.5-liter unit as an authorized dealer, shipping a genuine factory unit backed by the manufacturer warranty.
Chamber heating relies on iron-chrome wire rated at 1.1 kW, while an alumina-fiber interior isolates the heater from the work zone to prevent sample contamination. PID control through an upgraded R-thermocouple sensor holds temperature accuracy to ±1.0°C at 1150°C. Firmly sealed door construction keeps the chamber heat-tight for repeatable cycles.
Operating on a 115V supply, the furnace ships at roughly 100 lb in a 36 × 36 × 30 inch footprint. Manufactured in Japan, it is produced under ISO 9001:2015 and ISO 14001:2015 certified processes. Programmable operation supports up to 99 steps across 99 patterns with a repeat function.
Key Features
- High temperature accuracy: microprocessor PID control holds ±1.0°C at 1150°C with R-thermocouple sensing for repeatable runs.
- Contamination-resistant chamber: alumina porcelain hot plate keeps the heater out of the inner chamber, protecting samples from heater exposure.
- Programmable operation: up to 99 steps across 99 patterns, plus fixed-temperature, quick auto stop, and auto start/stop modes with a repeat function.
- Heat-tight construction: firmly sealed chamber door and alumina-fiber insulation maintain stable interior temperatures.
- Layered safety system: self-diagnostics, independent overheat prevention, key lock, calibration offset, electric leakage breaker, and auto recovery after power failure.
- Optional expansion: exhaust system, N₂ gas loading device with flow meter, RS232C communication, sample tray, and output terminals available.
How to Choose the Right Muffle Furnace
Matching a muffle furnace to your workflow means weighing the work-zone size against the temperature, accuracy, and control demands of your method. Use these axes to confirm fit .
- Capacity: the 1.5 L chamber (100 × 150 × 100 mm interior) suits small-batch ashing and sample testing; confirm crucible or boat dimensions fit the interior.
- Temperature range: a 100 to 1150°C span covers ashing, sintering, and ignition-loss work; verify your method's peak set point falls inside this range.
- Control type: microprocessor PID control with 99-step/99-pattern programming supports complex ramp-and-soak profiles versus fixed single-set-point units.
- Accuracy requirements: ±1.0°C at 1150°C and ±4.0°C distribution matter when methods specify tight thermal tolerance.
- Voltage and site power: this model runs on 115V; confirm available circuit capacity for the 1.1 kW heater.
- Safety needs: independent overheat prevention, leakage breaker, and self-diagnostics support unattended and regulated-lab operation.

Frequently Asked Questions
What is the operating temperature range of the Yamato FP103 muffle furnace?
The FP103 operates from 100 to 1150°C. It holds temperature accuracy to ±1.0°C and a temperature distribution of ±4.0°C at 1150°C, controlled by a microprocessor PID system with an R-thermocouple sensor.
How large is the chamber and what are the interior dimensions?
The FP103 offers a 1.5 L chamber with interior dimensions of 100 × 150 × 100 mm. This work zone suits small-batch ashing, sintering, and sample testing applications.
What voltage and power does the FP103 require?
The FP103 runs on a 115V supply and uses an iron-chrome wire heater rated at 1.1 kW. Confirm your circuit capacity supports the heater load before installation.
What materials are used in the chamber construction?
The interior uses alumina fiber insulation, and the heater sits behind an alumina porcelain hot plate so it is not exposed to the chamber, preventing sample contamination. The exterior is cold-rolled steel plate with a baked melamine resin finish.
Can the FP103 run programmed heating profiles?
Yes. The FP103 supports program operation of up to 99 steps across 99 patterns with a repeat function, plus fixed-temperature, quick auto stop, and auto start/stop modes.
