Utilize the latest technical advances in heating elements, insulation and temperature control integrated into a self-contained cabinet with Thermo Scientific™ Lindberg/Blue M™ LGO Box Furnaces.

Furnaces feature proprietary LGO (light gauge overbend) heating elements and Thermo Scientific™ Moldatherm™ insulation for efficient and economical transfer of heat to chamber, with low exterior temperatures. Variable heat-up rate eliminates thermal shock to materials with inherently quick heat up and cool down rates.

Feature exclusive LGO heating elements and Moldatherm insulation for efficient and economical transfer of heat to chamber, with low exterior temperatures
Variable heat-up rate eliminates thermal shock to materials with quick heat-up and cool-down rates
Air vent (1 in. dia., top) and air inlet (0.375 in. dia., rear) for inert atmosphere exchange; (Note: door is not gas-tight)
Self-tuning, digital instrumentation for precise temperature setpoint and display
Platinel II thermocouple for long-term stability
0.6 cu.ft. models feature vertical lift door; 2 cu.ft. models feature horizontal side swing door, hot side facing away from operator for protection.

Microparocessor control

Microprocessor-based self-tuning PID control provides optimum thermal process, prevents overshoot
Control panel designed for easy access and maintenance
Main power ON/OFF switch on control panel
Adjustable high-limit over-temperature protection
Simultaneous LED display of actual temperature vs. setpoint in °C or °F
Safety door switch interrupts power to heating element when door is opened; protects heating elements and minimizes exposure to end-user
Removable shelves for versatility
Moldatherm hearthplate supports load and prevents damage due to spillage

Flowmeter option (FM)

Available on selected models with “FM” designation (see chart)
Gas flowmeter, adjustable, located on front control panel
Adjustable flow rate, range 1.0 to 10.0 cu.ft./hr standard
Suitable for inert gas or air flow to chamber
Allows fresh air exchange for ashing applications
Not suitable for combustible or volatile gases
Note: Use with inert atmosphere will exhibit some leakage

Controller choices, all with over-temperature protection
