Lindberg/Blue M LGO 1200°C Box Furnaces

Overview

Overview

Utilize the latest technical advances in heating elements, insulation and temperature control integrated into a self-contained cabinet with these box furnaces.

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.

Key Features

• Choice of side hinge or vertical lift door
• Air vent (1 in. dia., top) and air inlet (0.375 in. dia., 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 Control

• 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

Digital, Single-Setpoint Controller

• 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) suffix designation

• Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control

Overtemperature Control (OTC)†

• 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

Flowmeter Option (FM) (Inert Atmosphere Only)

(FM)

• 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

Ordering Information:

Required power cord and hardwiring not included. Optional RS485 Digital Communications Port allows controller to be connected to a PC for remote monitoring and control of the furnace; up to 30 units can be connected to one PC.

†Specify Option

B for Overtemperature Control (OTC) when ordering.

Includes

One two-part shelf (0.6 cu. ft. models have one shelf position at center position; 2.0 cu. ft. models have three shelf positions)

Deliver consistent results with a furnace you can depend on to attain your daily goals. Thermo Scientific Box and Tube Furnaces come in a wide range of offerings to accommodate ordinary and technical tasks alike, such as: temperature ranges up to 1200°C, temperature control options to meet your application needs, and embedded or open heating elements designed to keep samples safe while maintaining reliable temperature uniformity.

Choosing between a box furnace or a tube furnace for your laboratory

Box Furnaces

• Used for processing larger samples or easy access to samples
• Small, medium and large box furnaces available
• Ashing applications in every industry and research laboratory
• Attributes include variable density insulation, double shell cabinets, long-life heating elements and vertical, horizontal side swing or swing down doors

Tube Furnaces

• Used for processing small samples or samples in an inert atmosphere
• Single and three-zoned designs for precise temperature control. Three zone control helps enable different temperatures in each zone.
• Materials testing, pyrolysis, and crystal growing applications
• Some models offer split-hinge design for ease of tube changing

View our quick application guide for choosing a furnace that is suitable for the workload you need. Choose from a variety of temperature control options, heating elements and furnace formats to meet your analytical requirements.

Lab Box Furnaces

Typically used for processing larger samples or to easily place and access samples. We offer a versatile selection of small, medium, and large box furnaces suitable for a variety of industrial and laboratory applications. Advanced engineering and specialized construction techniques include variable density insulation, double shell cabinets, long-life heating elements and side-swing doors (vertical or horizontal) or swing down doors.

Lab Tube Furnaces

Tube furnaces are typically used for processing small samples or heating in an inert atmosphere. The single and three-zoned construction is designed to create precise temperature control. Three-zone control enables the user to select a different temperature in each zone (e.g. for gas applications or material experiments). Some models offer split-hinge design, which easily allows you to change the tube.
