Product Details

The Thermo Scientific Thermolyne Largest Tabletop Muffle Furnace provides triple the usable working area with two supplied accessory refractory shelves. Designed for safe operation, these furnaces are available in three temperature control models. They are ideal for annealing glass, determinations of volatiles, catalyst research and ashing organic and inorganic samples.

Includes the C1 Digital Controller

Programmable with one (1) stored program of eight (8) segments.

Each segment includes one ramp and one dwell, so you can program 8 ramp/dwell cycles.

The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time.

An LED display simultaneously shows both setpoint and actual furnace temperatures.

A mechanical overtemperature protection relay is also included.

User-selectable overtemperature protection

Open thermocouple protection

Adjustable power output from 1 to 100%

Heating elements are on chamber top, bottom and sides for enhanced temperature uniformity

Built-in vent port removes undesirable contaminants and moisture to extend the life of the element and unit

Rear of chamber incorporates a 0.38-inch diameter port for monitoring chamber temperatures with independent measuring devices

Critical electronic components and heating elements are protected by a 35A circuit breaker

Door safety switch stops power to the heating elements when door opens

Applications: Annealing glass, determinations of volatiles, catalyst research and ashing organic and inorganic samples

Includes two refractory shelves, max weight 11.3 kg (25 lbs) per shelf

NOTE: Electrical connection requires fixed wiring (no power cord included).
