Why order the FP303 from LabSupplies.com
Key Features
- Contamination-resistant heating: alumina porcelain hot plate shields the iron-chrome heater from the chamber, protecting samples.
- Program operation: up to 99 steps across 99 patterns with a repeat-operation function for multi-stage profiles.
- Sealed chamber: firmly sealed door provides excellent heat tightness across the 100 to 1150°C range.
- Integrated safety: self-diagnostics, key lock, independent overheat prevention, and electric leakage breaker.
How to Choose the Right Muffle Furnace
- Capacity: the 7.5 L chamber (200 × 250 × 150 mm interior) sets how many crucibles or samples you can process per batch.
- Footprint and weight: Yamato lists external dimensions (W × D × H) of 446 × 504 × 565 mm (17.6 × 19.8 × 22.2 in); packed for shipping it measures 36 × 36 × 35 in at 174 lb.

Frequently Asked Questions
What is the temperature range of the FP303 muffle furnace?
The FP303 operates from 100 to 1150°C. It holds ±1.0°C temperature accuracy at 1150°C using microprocessor PID control, with a temperature distribution of ±4.0°C and a gradient of 14°C at that ceiling.
How large is the chamber and what are the interior dimensions?
The chamber capacity is 7.5 liters, with interior dimensions of 200 × 250 × 150 mm. This sizing determines how many crucibles or samples you can process per batch.
What voltage options are available?
Two voltage options are offered: model FP303 runs on 115V and model FP313 runs on 220V. Both share identical performance and features; only the input voltage differs. The unit uses a 2.4 kW iron-chrome heater.
What safety features are included?
Safety devices include self-diagnostic functions covering sensor error, heater disconnection, triac short-circuit, main relay failure, and automatic overheat prevention. Additional protection includes a key lock, independent overheat prevention, and an electric leakage breaker.
Can the FP303 run multi-stage temperature programs?
Yes. The microprocessor controller supports program operation of up to 99 steps across 99 patterns, plus a repeat-operation function. It also offers fixed-temperature, quick auto stop, and auto start/stop modes.
What is the difference between FP-303 and FP-313?
FP-303 is the 115V configuration. FP-313 is the 220V configuration. Order the catalog number that matches your facility's electrical supply.
