Froilabo AC Series Precision Drying Ovens (AC 60 / AC 120 / AC 240)

Overview

The Froilabo AC Series Precision Drying Ovens are engineered for reproducible thermal processing in regulated laboratory and quality control environments. Designed and manufactured in France, these forced-convection ovens utilize a robust air circulation system with tangential fan and optimized duct geometry to ensure rapid heat-up and exceptional temperature uniformity across the entire working chamber. The core measurement principle relies on closed-loop PID-controlled resistive heating combined with high-stability platinum RTD (Pt100) sensors positioned within the airflow path and near the chamber walls—enabling precise setpoint tracking and minimizing thermal gradients. Applications span residual solvent removal, gravimetric moisture analysis (in compliance with ASTM E121–22 and ISO 712), pre-conditioning of polymer samples prior to mechanical testing, sterilization validation support, and stability studies under defined thermal stress conditions. All models meet IEC 61010-1 safety requirements and are constructed to support long-term GLP/GMP-aligned operation.

Key Features

• High-integrity AISI 304 stainless steel interior chamber and shelving—resistant to corrosion from organic solvents, acids, and repeated thermal cycling
• Double-glazed, thermally insulated observation door with food-grade silicone gasket, minimizing heat loss while enabling real-time visual monitoring without compromising chamber integrity
• Digital PID temperature controller with intuitive front-panel interface, 0.1°C display resolution, and independent over-temperature safety cut-off (adjustable up to 280°C)
• Optimized forced-air convection system delivering uniform airflow distribution—validated via ISO/IEC 17025-accredited mapping protocols at multiple load configurations
• Epoxy-polyester powder-coated exterior housing providing mechanical durability and chemical resistance in shared lab environments
• Standardized accessory ports (e.g., 25 mm diameter) for integration with external data loggers, purge gas lines, or humidity sensors
• Modular shelf design with reinforced ribbed supports and precisely calibrated load ratings—ensuring structural integrity under full operational load

Sample Compatibility & Compliance

The AC series accommodates a broad range of sample formats—including Petri dishes, weighing boats, crucibles, glassware, and polymer test specimens—without risk of cross-contamination or dimensional distortion. Chamber geometry and airflow dynamics have been validated per EN 60068-3-5 for thermal stability testing and are routinely employed in laboratories performing USP <1208> drying procedures and ISO 11358-1 polymer thermal characterization. Each oven is supplied with CE marking, RoHS compliance documentation, and a factory calibration certificate traceable to national standards (LNE, France). Optional IQ/OQ documentation packages are available to support FDA 21 CFR Part 11–compliant validation workflows.

Software & Data Management

While the base configuration operates via standalone digital control, all AC models feature analog output (0–10 V or 4–20 mA) and RS-485 Modbus RTU interface for seamless integration into centralized laboratory information management systems (LIMS) or SCADA platforms. When paired with Froilabo’s optional DataLogger Pro software (v3.2+), users gain access to real-time trend visualization, automated CSV export, audit-trail-enabled event logging (including door openings, temperature deviations, and alarm triggers), and electronic signature support aligned with ALCOA+ data integrity principles. Raw sensor data is timestamped with microsecond precision and stored locally on non-volatile memory—ensuring continuity during power interruptions.

Applications

• Moisture content determination in pharmaceutical excipients and active ingredients (per USP <731> and Ph. Eur. 2.2.32)
• Thermal aging of elastomers and composites for automotive and aerospace qualification testing
• Drying of filter papers and gravimetric filters prior to ash content analysis (ASTM D2974)
• Curing of thin-film coatings and adhesives under controlled ramp-hold profiles
• Pre-drying of reference standards and certified reference materials (CRMs) in metrology labs
• Stabilization of hygroscopic reagents prior to analytical weighing or titration

FAQ

What safety certifications do the AC series ovens hold?
All units comply with IEC 61010-1:2010 for electrical safety in laboratory equipment and carry CE, UKCA, and RoHS markings. Optional third-party certification to UL 61010-1 is available upon request.

Can the oven be used for inert-atmosphere drying?
Yes—standard gas inlet/outlet ports support nitrogen or argon purging. For continuous inert atmosphere operation, we recommend pairing with a mass flow controller and pressure-regulated supply line.

Is temperature mapping data provided with the unit?
A basic 9-point empty-chamber uniformity report is included. Full 3D thermal mapping with load simulation (per ISO/IEC 17025) can be commissioned separately through Froilabo’s Application Support Lab.

How often should routine calibration be performed?
We recommend annual calibration using NIST-traceable Pt100 probes. Internal sensor verification checks can be executed daily via the built-in self-test function accessible through service mode.

Are spare shelves and accessories available?
Yes—custom stainless steel shelves (including perforated, wire mesh, and solid variants), additional silicone gaskets, and calibration adapters are stocked and shipped globally within 5 business days.
