Muffle Furnace With Communication Port 23.6L Overview
The Muffle Furnace With Communication Port 23.6L (FO711CR) from Yamato Scientific is a high-temperature muffle furnace built around a 23.6 L chamber and a 100 to 1150°C operating range. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer, shipping genuine product from the USA.
Inside the chamber, ceramic fiber insulation surrounds the work zone, while the exterior combines steel, a melamine and epoxy composite resin coating, and SUS304 components. A 3.5 kW iron-chrome wire heater drives the load, and long-life R-thermocouple sensing holds accuracy to ±2°C at 1150°C. PID control through the VS6 controller manages every program step.
Yamato lists external dimensions (W × D × H) of 507 × 605 × 727 mm (20.0 × 23.8 × 28.6 in); packed for shipping it measures 36 × 36 × 38 in at 215 lb. Country of origin is listed as CH, and the unit ships from the USA. CE documentation is available for this model.
Key Features

- PID program control: VS6 controller supports up to 6 patterns — 30 steps × 1, 15 steps × 2, or 10 steps × 3.
- Long-life sensing: upgraded R-thermocouple sensors paired with a 3.5 kW iron-chrome wire heater.
- Sealed chamber door: firmly sealed door delivers strong heat tightness across the work zone.
- Layered safety: self-diagnostic functions, earth-leakage breaker, overheat prevention device, lock function, calibration offset, and auto-recovery after power failure.
How to Choose the Right Muffle Furnace
Selecting a muffle furnace comes down to matching chamber size, temperature ceiling, and control capability to the work the lab performs. Use the criteria below to confirm the FO711CR fits your application.
- Capacity: the 23.6 L chamber (270 × 350 × 250 mm interior) determines batch size and sample throughput per cycle.
- Control type: PID programming with up to 6 patterns matters when processes require staged ramp, hold, and cool profiles.
- Voltage and power: confirm the 220V supply and 3.5 kW heater load against available circuits before installation.
- Footprint and weight: Yamato lists external dimensions (W × D × H) of 507 × 605 × 727 mm (20.0 × 23.8 × 28.6 in); packed for shipping it measures 36 × 36 × 38 in at 215 lb.
