Carbolite Gero AX Series Benchtop Laboratory Oven

Overview

The Carbolite Gero AX Series benchtop laboratory oven is an engineered solution for precise, repeatable thermal processing in research, quality control, and routine analytical laboratories. Designed around forced-air convection architecture, the AX oven ensures rapid heat-up times and exceptional temperature uniformity—typically ±1.5 °C across the working volume at 250 °C—by integrating a high-efficiency axial fan and optimally positioned heating elements. Its core function supports drying, curing, annealing, conditioning, and stabilization of samples where strict thermal consistency and chemical inertness are required. Unlike gravity-convection ovens, the fan-assisted airflow minimizes thermal stratification and accelerates equilibration, particularly critical for multi-layer loading or time-sensitive protocols. The unit complies with BS EN 61010-2-010:2003, addressing safety requirements for laboratory equipment used in controlled environments under electrical and thermal stress.

Key Features

• Digitally controlled thermal environment via the R38 PID controller, offering intuitive setpoint programming, real-time deviation monitoring, and programmable ramp/soak profiles.
• Chemically resistant AISI 304 stainless steel interior chamber, resistant to organic solvents, mild acids, and alkaline residues—ideal for pharmaceutical residual solvent removal or polymer conditioning.
• Robust door sealing system incorporating a high-temperature silicone gasket and spring-loaded latch mechanism, ensuring consistent thermal integrity and minimizing ambient air infiltration during operation.
• Two adjustable nickel-chromium crucible supports included as standard, enabling flexible sample placement for gravimetric analysis, ashing pre-treatment, or ceramic sintering trials.
• Modular design accommodating optional safety and operational enhancements—including over-temperature cut-out (independent of main controller), digital countdown timer for unattended endpoint management, and lockable door kits for secure access control in shared lab facilities.

Sample Compatibility & Compliance

The AX oven accommodates a broad range of sample formats—including Petri dishes, weighing boats, crucibles, glassware, and polymer substrates—within its three standardized chamber volumes (30 L, 60 L, 120 L). Its maximum operating temperature of 250 °C aligns with common ISO and ASTM drying standards (e.g., ISO 787-2, ASTM D2240, USP ). The stainless steel chamber and non-shedding internal surfaces meet GLP-compliant cleaning validation requirements. Units shipped to regulated environments may be supplied with factory calibration certificates traceable to UKAS-accredited standards. The low-voltage variant (≤220 V) supports deployment in regions with unstable grid infrastructure or mobile laboratory configurations without requiring step-down transformers.

Software & Data Management

While the AX series operates via standalone hardware control, the R38 controller supports analog output (0–10 V or 4–20 mA) for integration into centralized building management systems (BMS) or data acquisition platforms. Optional RS485 Modbus RTU interface enables remote parameter readout and basic alarm status polling when connected to compatible SCADA or LIMS infrastructure. All event-driven alarms—including over-temperature fault, door-open detection, and heater failure—are logged internally with timestamping. For FDA-regulated workflows, optional audit trail firmware upgrades support 21 CFR Part 11-compliant electronic record generation when paired with validated third-party software layers.

Applications

• Drying of moisture-sensitive powders and hygroscopic compounds prior to Karl Fischer titration or XRD analysis.
• Curing of epoxy-coated substrates and printed circuit board laminates under defined thermal profiles.
• Conditioning of filter media and desiccant materials per ISO 9001 environmental simulation protocols.
• Pre-heating of crucibles and volumetric glassware in analytical chemistry workflows requiring thermal stability.
• Stabilization of reference standards and certified reference materials (CRMs) under controlled humidity-free conditions.

FAQ

What is the typical temperature uniformity specification across the working chamber?
At 250 °C, the AX oven achieves ±1.5 °C uniformity (measured per IEC 60068-3-5) at three horizontal planes within the load zone.
Can the AX oven be used for ashing applications?
No—the AX series is not rated for oxidative ashing; its maximum temperature and insulation design do not meet the requirements of ASTM D2974 or ISO 1171. For ashing, Carbolite Gero’s AAF or HTF series muffle furnaces are recommended.
Is calibration documentation provided with shipment?
Standard units include a factory test report verifying temperature accuracy and safety interlock functionality. UKAS-traceable calibration certificates are available upon request and subject to additional lead time and cost.
How is over-temperature protection implemented?
An independent mechanical over-temperature limiter (settable up to 280 °C) interrupts power to the heating elements if the primary PID controller fails or drifts beyond user-defined thresholds.
Are replacement gaskets and heating elements available as service parts?
Yes—standard spare parts packages include door gaskets, fan assemblies, heating element sets, and thermocouple probes, all stocked globally through Carbolite Gero’s authorized distribution network.
