Laboratory Muffle Furnace

A laboratory muffle furnace (ashing furnace) is essential for ash content determination, loss-on-ignition (LOI), annealing, calcination, heat treatment, and material testing. Hawach offers muffle furnaces from 1000°C to 1300°C, with chamber sizes ranging from 2L to 30L (inner dimensions from 20×12×8 cm to 50×30×20 cm). All models feature programmable PID controllers, ceramic fiber insulation for fast heating, double-shell construction, and embedded heating elements. Designed for workflows compatible with Thermo Scientific Thermolyne, Nabertherm, and Carbolite – a cost-effective alternative for food, pharma, environmental, and industrial QC labs.

Muffle Furnace Types – 1000°C, 1200°C, 1300°C Models

Choose the right furnace based on your maximum required operating temperature. Hawach furnaces cover the most common ranges for routine QC and materials testing.

Selection tip: For most food, pharma, and environmental QC laboratories, a 1000–1200°C muffle furnace is sufficient. For ceramic sintering and advanced materials research, consider 1300°C models.

Typical Applications of Laboratory Muffle Furnaces

Hawach muffle furnaces are used across a wide range of industries. The table below summarizes common applications and their typical temperature ranges.

Muffle Furnace for Ash Content Determination – Industry Standards

Ash content determination is one of the most common applications. Hawach furnaces meet the temperature accuracy required for regulated methods.

Complete Specifications – Hawach Muffle Furnace Series (1000°C, 1200°C, 1300°C)

All models feature programmable PID controller, ceramic fiber insulation, double-shell construction, embedded heating elements, door safety switch, and over-temperature protection.

Note: 1300°C models (19041009, 19041010) are suitable for advanced ceramic sintering and high-temperature materials research. For 1400°C and above, contact us for custom solutions.

Capacity Selection – How Many Crucibles Can You Process?

Choose chamber size based on your sample throughput. Estimates assume standard 30 mL porcelain crucibles (approx. 40 mm diameter).

Muffle Furnace vs Laboratory Oven – Key Differences

Key Features of Hawach Muffle Furnaces

• Programmable PID controller: Multi-segment ramp/hold cycles, digital display, ±1°C accuracy, over-temperature protection.
• Ceramic fiber insulation: Low thermal mass, fast heating (≤30 min to set temperature), energy-
• Double-shell construction with air jacket: External surface stays cool; improves operator safety.
• True muffle design: Embedded heating elements – samples isolated from direct heating wires.
• Door safety switch: Power cuts off when door opens.
• Built-in exhaust vent: Removes fumes generated during ashing.
