Thermo Fisher M110 Benchtop Box-Type Muffle Furnace

Overview

The Thermo Fisher M110 is a compact, benchtop box-type muffle furnace engineered for precision thermal processing in research laboratories, quality control environments, and routine analytical workflows. Designed around the fundamental principle of resistive heating within a fully isolated chamber—where radiant heat transfer is minimized through high-efficiency ceramic fiber insulation—the M110 delivers stable, repeatable temperature profiles up to 1100°C. Its double-wall air-gap construction and horizontally hinged side-opening door collectively reduce operator exposure to radiant heat during loading/unloading, supporting ergonomic safety compliance in ISO/IEC 17025-accredited labs. The furnace operates without direct flame or combustion gases, ensuring inert thermal treatment ideal for ashing, calcination, heat treatment of ceramics, and gravimetric analysis per ASTM E1866 and USP <231>. With a 9 L working volume and optimized internal geometry, the M110 maintains ±7°C temperature uniformity across the entire chamber at maximum setpoint—a performance benchmark validated under no-load conditions per IEC 60068-2-2.

Key Features

• Benchtop footprint (576 × 752 × 720 mm) enables integration into space-constrained lab environments without dedicated floor mounting.
• Horizontally opening side door minimizes vertical heat plume exposure and improves access ergonomics during sample insertion and retrieval.
• Multi-layer ceramic fiber insulation—certified asbestos-free—provides low thermal conductivity (<0.08 W/m·K at 800°C) and rapid cooldown rates post-cycle.
• Resistance heating elements are recessed into grooved sidewalls and fully encapsulated beneath protective ceramic sheaths, extending service life and preventing oxidation-induced hot-spot formation.
• Adjustable over-temperature limit switch functions independently from the main controller, offering redundant protection for both samples and furnace integrity.
• CE-marked design complies with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, including electromagnetic compatibility (EMC) per EN 61326-1.

Sample Compatibility & Compliance

The M110 accommodates standard crucibles (alumina, platinum, silica), porcelain boats, and ceramic setters up to 200 mm wide × 150 mm high × 300 mm deep. Its muffle architecture isolates samples from heating element emissions, making it suitable for applications requiring chemical purity—such as residue-on-ignition (ROI) testing per AOAC 920.153, ash content determination per ISO 2171, and pre-treatment of catalyst supports prior to BET surface area analysis. All materials contacting the chamber interior conform to RoHS 2011/65/EU restrictions. The furnace meets GLP documentation requirements when paired with external data loggers compliant with FDA 21 CFR Part 11 audit trail standards.

Software & Data Management

While the M110 features an integrated digital PID controller with manual setpoint programming and ramp/soak functionality, it does not include embedded data logging or Ethernet connectivity. For regulated environments, Thermo Fisher recommends interfacing the analog output (0–10 V or 4–20 mA) with third-party validated data acquisition systems (e.g., Omega iSeries or Siemens Desigo CC) to generate ALCOA+ compliant records—including time-stamped temperature profiles, operator ID, and cycle validation logs. Firmware updates are performed locally via USB port using Thermo Fisher’s certified configuration utility, with version history traceable per internal change control SOPs.

Applications

• Gravimetric analysis: ash content, volatile matter, fixed carbon in coal, biomass, and foodstuffs.
• Thermal pre-treatment of XRD and SEM samples to remove organic binders without introducing metallic contamination.
• Calibration of thermocouples and RTDs in accordance with ASTM E230/E230M Annex A3.
• Heat aging studies for polymer composites and electronic encapsulants per IPC-TM-650 2.6.22.
• Pre-firing of ceramic green bodies and sintering trials under controlled oxidizing atmospheres (ambient air only).

FAQ

What is the recommended maintenance schedule for the M110 furnace?
Thermo Fisher recommends visual inspection of door gasket integrity and ceramic fiber condition every 200 operating hours, with full calibration verification annually using NIST-traceable reference thermocouples.
Can the M110 be used under inert or reducing atmospheres?
No—the M110 is rated for ambient air operation only. It lacks gas inlet/outlet ports, pressure rating, or sealed purge capability; use of inert gases may compromise insulation integrity and void warranty.
Is the temperature uniformity specification verified under load or no-load conditions?
Per IEC 60068-2-2 Clause 5.2, the ±7°C uniformity value is measured at steady-state 1100°C with an empty chamber using nine calibrated thermocouples positioned on a 3×3 grid per ASTM E220.
Does the M110 support programmable multi-segment heating profiles?
Yes—the built-in controller supports up to 8 segments with independent ramp rates, soak times, and cooling steps, configurable via front-panel keypad or optional PC software (Thermo Fisher FurnaceControl v2.1).
What safety certifications apply to the M110 in North America?
The unit carries cULus listing per UL 61010-1 and CAN/CSA C22.2 No. 61010-1, confirming compliance with North American electrical safety requirements for laboratory equipment.
