LabCompanion HH15-72 High-Temperature Drying Oven

Overview

The LabCompanion HH15-72 High-Temperature Drying Oven is an engineered thermal processing system designed for precision drying, baking, heat treatment, sterilization, and temperature stabilization of samples across industrial R&D laboratories and quality control environments. Built upon a robust convection-based heating architecture, the oven utilizes forced horizontal airflow to ensure uniform thermal distribution throughout the chamber—critical for repeatable material conditioning, moisture removal, and pre-treatment protocols in compliance with ASTM D1654, ISO 188, and USP . Its operational range extends from ambient temperature up to 260 °C, supporting applications requiring extended dwell times at elevated temperatures without thermal drift or hot-spot formation.

Key Features

• High-reliability PID microprocessor controller with simultaneous PV (Process Value) and SV (Set Value) digital display; intuitive keypad interface for precise setpoint entry and real-time monitoring.
• Honeycomb-style heating elements provide rapid thermal response and stable power delivery, minimizing overshoot during ramp phases.
• Dual-layer tempered glass observation window enables continuous visual inspection while maintaining thermal integrity and operator safety.
• Internally lined with SUS430 stainless steel (≥1.2 mm), offering superior corrosion resistance against acidic vapors and repeated thermal cycling.
• Externally constructed from SECC cold-rolled steel with electrostatic powder coating (≥1.5 mm), ensuring mechanical durability and long-term finish stability.
• Thermal insulation composed of imported rock wool (density ≥100 kg/m³), delivering low thermal conductivity (<0.04 W/m·K) and reduced external surface temperature rise.
• Independent over-temperature cut-off circuit—mechanically isolated from the main controller—acts as a fail-safe layer compliant with IEC 61000-4-5 surge immunity and EN 60519-2 safety standards.

Sample Compatibility & Compliance

The HH15-72 accommodates standard laboratory sample carriers including porcelain crucibles, aluminum trays, glass Petri dishes, and metal test specimens up to 300 mm in height. Its chamber dimensions (W×D×H: 450 × 450 × 450 mm) support batch processing under GLP/GMP-aligned workflows. The unit conforms to electrical safety requirements per UL 61010-1 and CE marking directives (2014/30/EU EMC, 2014/35/EU LVD). Optional validation documentation—including IQ/OQ protocols, calibration certificates traceable to NIST standards, and temperature mapping reports—is available upon request for regulated environments subject to FDA 21 CFR Part 11 and Annex 11 requirements.

Software & Data Management

While the HH15-72 operates via embedded hardware control, it supports integration into centralized lab management systems through optional RS-485 Modbus RTU communication modules (sold separately). This enables remote parameter readout, event logging, and alarm status polling within SCADA or LIMS platforms. All internal timer functions—including elapsed time tracking, end-of-cycle alerts, and automatic heater deactivation—are logged with timestamped entries stored in non-volatile memory. Audit trails meet minimum ALCOA+ criteria for data integrity when used with validated external data acquisition systems.

Applications

• Moisture content determination per AOAC 950.46 and ISO 5530-1 for food, feed, and pharmaceutical raw materials.
• Pre-drying of filter papers, weighing boats, and analytical glassware prior to gravimetric analysis.
• Thermal aging studies of polymer films, adhesives, and encapsulants under controlled isothermal conditions.
• Baking of ceramic green bodies and sintering pre-treatment of metallurgical powders.
• Heat sterilization of reusable laboratory tools where steam autoclaving is unsuitable.
• Stabilization of reference standards and hygroscopic reagents prior to analytical use.

FAQ

What is the maximum recommended continuous operating temperature?
The HH15-72 is rated for continuous operation up to 260 °C. Sustained use above this threshold may compromise heater lifespan and insulation performance.
Does the oven include a built-in data logger?
No—the base configuration features only local display and timer functionality. External data logging requires integration via RS-485 or analog output modules (optional accessories).
Can the airflow direction be reversed or vertically adjusted?
Airflow is fixed in horizontal orientation; however, internal adjustable baffles allow fine-tuning of cross-chamber velocity profiles to accommodate asymmetric load configurations.
Is the chamber volume validated for temperature uniformity per ISO 17025?
Yes—temperature uniformity mapping (±1.5 °C at 200 °C, 3-point verification) can be performed using calibrated thermocouples and documented per ISO/IEC 17025 clause 7.8.2 upon installation qualification.
Are replacement parts such as heaters or controllers available directly from LabCompanion?
All critical subassemblies—including SSR drivers, K-type sensors, honeycomb heating panels, and PID controller boards—are stocked and supplied with full technical documentation and RoHS-compliant certifications.
