UP-6119 Box Type Laboratory Muffle Furnace for Ash & Carbon Residue Test with 1200℃ Maximum Temperature

This box type laboratory muffle furnace is a high-temperature resistance furnace specially designed for ash content and carbon residue testing of crude oil, fuel oil, lubricant and bitumen in petroleum laboratories. It also supports material sintering, metal heat treatment, sample calcination, burnout and other high-temperature experiments for the material, chemical and mining industries.

The furnace adopts a high-quality ceramic fiber insulation lining and an intelligent digital temperature controller, delivering fast heating speed and excellent temperature uniformity. It is widely used by refineries, third-party inspection laboratories, petrochemical factories, universities and research institutes.

1. High temperature resistant ceramic fiber inner chamber: light weight, low heat loss and energy saving.
2. Precise PID temperature control with over-temperature protection for safe and stable operation.
3. Stainless steel outer cabinet, anti-rust and easy to clean; side heating wire structure.
4. Simple door lock design for convenient sample loading and unloading.
5. Multiple chamber size options, with customized working dimensions available.
6. Meets ASTM D482 (Ash Content) and ASTM D4530 (Carbon Residue) standards for petroleum testing.
