LabCompanion HH-72 High Temperature Aging Test Chamber

Overview

The LabCompanion HH-72 High Temperature Aging Test Chamber is an engineered environmental test system designed for accelerated thermal aging, drying, curing, and stability evaluation of materials under controlled elevated temperature conditions. Based on the principle of forced convection heating with precision PID-controlled resistive heating elements, the chamber maintains stable thermal environments from ambient +5°C up to 300°C—enabling compliance-driven testing in accordance with ASTM D573, ISO 188, IEC 60068-2-2, and USP thermal stability protocols. Its robust architecture supports long-duration exposure tests required for polymer degradation analysis, electrical component qualification, pharmaceutical excipient stability screening, and coating adhesion validation.

Key Features

• Microprocessor-based high-accuracy temperature controller with intuitive up/down key interface; simultaneously displays setpoint and real-time chamber temperature
• Dual-stage over-temperature protection: audible alarm at first threshold, automatic power cutoff at second threshold—meeting IEC 61000-4-11 and UL 61010-1 safety requirements
• Optimized forced-air circulation system with rear-mounted centrifugal blower and strategically positioned outlet ducts ensures ±1.5°C temperature uniformity across the entire working volume
• Mirror-finish SUS304 stainless steel interior chamber resists oxidation and facilitates cleaning; powder-coated carbon steel exterior provides mechanical durability and corrosion resistance
• High-density compressed glass wool insulation (≥80 mm thickness) minimizes thermal loss and improves energy efficiency during extended operation cycles
• Modular shelf configuration: 2–6 adjustable stainless steel trays included; load capacity per shelf: 15 kg (uniformly distributed)
• Finned tubular heating elements with aluminum heat sinks ensure rapid thermal response and extended service life
• Programmable delayed fan shutdown function available as optional upgrade—supports gradual cooldown to prevent thermal shock on sensitive samples

Sample Compatibility & Compliance

The HH-72 accommodates a broad range of sample types including elastomers, thermoplastics, PCB assemblies, battery cells, pharmaceutical tablets, and composite laminates. Its internal dimensions (450 × 400 × 400 mm) support standard test specimen racks per ASTM D395 and ISO 1431-1. The chamber’s construction and control logic are aligned with GLP and GMP documentation prerequisites: all temperature setpoints, dwell times, and alarm events are traceable via optional RS485/Modbus interface for integration into LIMS or MES platforms. It satisfies essential requirements of FDA 21 CFR Part 11 when paired with validated data logging software and electronic signature modules.

Software & Data Management

While the base unit operates via standalone microcontroller, LabCompanion offers optional PC-based monitoring software compatible with Windows 10/11. This application enables real-time graphing of chamber temperature, event logging with time-stamped timestamps, export to CSV/PDF formats, and configurable alarm notifications via email or SMS. Audit trail functionality records operator ID, parameter changes, and system status transitions—supporting ISO/IEC 17025 accreditation needs. Data integrity is preserved through cyclic redundancy check (CRC) validation and write-protected archive folders.

Applications

• Accelerated aging studies for automotive seals, gaskets, and under-hood components per SAE J2238
• Thermal endurance testing of wire insulation and cable jacketing materials (UL 1581, CSA C22.2 No. 0.3)
• Stability assessment of active pharmaceutical ingredients (APIs) and final dosage forms under ICH Q1A(R2) guidelines
• Moisture removal from hygroscopic powders prior to FTIR or XRD analysis
• Curing validation of epoxy adhesives and silicone encapsulants in electronics manufacturing
• Pre-conditioning of sensors and MEMS devices before functional characterization

FAQ

What is the maximum continuous operating temperature of the HH-72?
The HH-72 is rated for continuous operation at 300°C, with thermal stability maintained within ±1°C under steady-state conditions.
Does the chamber meet international safety standards?
Yes—it complies with EN 61010-1 (2010), IEC 61000-4-2/4-3, and carries CE marking for electromagnetic compatibility and low-voltage directive conformity.
Can the internal chamber be customized for non-standard sample geometries?
Custom internal configurations—including modified shelf spacing, additional access ports, or inert gas purge fittings—are available upon request and subject to engineering review.
Is calibration certificate included with shipment?
A factory-issued NIST-traceable temperature calibration report (at three points: 100°C, 200°C, and 300°C) is provided standard; UKAS-accredited calibration is available as an add-on service.
What maintenance intervals are recommended for optimal performance?
Blower motor lubrication every 12 months, heater element resistance verification semiannually, and door gasket inspection prior to each critical test cycle.
