In India, 2-liter muffle furnaces are widely used for laboratory applications such as ashing, heat treatment, and sintering. These benchtop units are typically designed for high-temperature accuracy and uniform heating.
Key Features to Look For
- Insulation: Modern units use lightweight ceramic fiber insulation for faster heating and better energy efficiency.
- Construction: Look for a powder-coated mild steel outer body or double-walled construction to keep the exterior safe to touch.
- Safety: Ensure the model includes a safety fuse or automatic power cut-off when the door is opened.
- Power Consumption: Usually rated between 2.0 kW and 3.5 kW.
- Power Supply: Typically requires a single-phase 230V AC connection.
- Controller: Most modern units use PID digital temperature controllers with LED/LCD displays for accuracy.
