Lindberg/Blue M™ LGO™ Box Furnaces, Thermo Scientific

Thermo Scientific™ LGO Series Box Furnaces feature the latest technical advances in heating elements, insulation and temperature control, all integrated into a self-contained cabinet. Furnaces feature proprietary LGO (light gauge overbend) 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
• Choice of side hinge or vertical lift door
• Air vent (1 inch diameter, top) and air inlet (0.375 inch diameter, rear) for inert atmosphere exchange (may experience some leakage at door)
• 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

• Microprocessor-based self-tuning PID control (proportional, integral, derivative) 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 overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• Can be configured to display temperature in either °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

• Single segment, single setpoint, one ramp to setpoint
• Digital Single-Program, Multiple-Segment Programmable Controller
• Single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control
• Digital Multiple-Program, Multiple-Segment Programmable Controller
• Available on models with P designation
• Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control

• Adjustable digital overtemperature control, available on selected models with B suffix designation
• Protects furnace and load in the event of primary control circuit failure
• Overrides main controller and shuts off power to furnace if high limit is reached
• Manual reset required for safety
• Operates via magnetic contacts through signal from independent thermocouple

• Available on selected models with FM designation
• Gas flowmeter, adjustable, located on front control panel
• Adjustable flowrate, range 1.0 to 10.0 cu.ft./hr. standard
• Suitable for inert gas or airflow to chamber
• Allows fresh air exchange for ashing applications
• Not suitable for combustible or volatile gases
