15L High Temperature Furnace – Model 931

15L High Temperature Furnace – Model 931

Brand Chemical Supplies offers the Model 931, a high-performance muffle furnace engineered for laboratories that require consistent, high-heat processing up to 1200°C. While the 932 model is built for extreme 1500°C applications, the Model 931 serves as the industrial standard for routine ashing, heat treatment, and material testing, offering a perfect balance of rapid heating and energy efficiency.

Technical Specifications

Key Features & Benefits

• Versatile Thermal Processing: Designed for a wide range of applications, this furnace excels at a continuous operating temperature of 1150°C, making it ideal for standard ashing procedures and loss-on-ignition (LOI) testing.

• Precision PID Control: Equipped with a digital microprocessor controller that provides accurate temperature maintenance and a clear display of both setpoint and actual chamber temperature.

• Rapid Heat-Up: The 4.5 kW heavy-duty heating elements are embedded in high-quality ceramic muffle plates, ensuring fast ramp-up times and excellent temperature uniformity across the 15L chamber.

• Efficient Insulation: The furnace utilizes low-thermal-mass ceramic fiber insulation. This allows the unit to reach high temperatures quickly while keeping the external casing cool and reducing overall power consumption.

• “Up-and-Away” Door Design: The counterbalanced door opens vertically, ensuring the incandescent hot face of the door insulation is always directed away from the operator during loading and unloading.

• Safety First: An integrated safety switch automatically cuts power to the heating elements when the door is opened, protecting the operator from electrical contact and radiant heat.

Primary Applications

• Analytical Chemistry: Ashing of organic and inorganic samples and determining volatile matter.

• Metallurgy: Hardening, tempering, and annealing of small metal components and tools.

• Mining & Mineralogy: Fusing samples and conducting ignition tests on ore samples.

• Ceramics & Glass: Small-batch firing of specialized ceramic parts or glass fusing experiments.

• Dental Laboratories: Burn-out of investment molds and porcelain firing.

Installation & Operational Care

• Electrical Requirements: Unlike the three-phase 932 model, the Model 931 operates on a Single Phase (230V) supply. However, due to the 4.5 kW draw, it should be connected to a dedicated high-amperage circuit.

• Ventilation: We recommend placing the furnace under an extraction hood or in a well-ventilated area, especially when processing samples that release smoke or corrosive gases.

• Chamber Longevity: To protect the floor of the furnace, it is recommended to use a ceramic hearth plate or tray to prevent chemical spills from coming into direct contact with the heating elements.
