Atlas SUNTEST XXL+ FD Xenon Arc Weathering Test Chamber

Overview

The Atlas SUNTEST XXL+ FD is a high-capacity, air-cooled xenon arc weathering test chamber engineered for accelerated light stability and photodegradation evaluation under controlled environmental conditions. It operates on the principle of xenon arc irradiation—mimicking full-spectrum sunlight including UV, visible, and near-infrared wavelengths—with spectral output calibrated to meet CIE Publication No. 85 and ISO 4892-1 requirements. Its advanced optical architecture incorporates aluminum reflectors, precision lamp holders, and interchangeable filter slots to support multiple irradiance profiles—including daylight, window glass, and daylight ID65 filters—enabling simulation of both outdoor solar exposure and indoor retail lighting environments. Designed specifically for fast-moving consumer goods (FMCG), food & beverage packaging, pharmaceuticals, and polymer-based 3D products, the SUNTEST XXL+ FD delivers reproducible, traceable, and standards-compliant aging data essential for shelf-life prediction, regulatory submissions (e.g., ICH Q1B), and material qualification.

Key Features

• Large 3000 cm² exposure area (740 × 368 mm) accommodates full-size bottles, cartons, pouches, and irregular 3D samples—ideal for real-world packaging validation.
• SunCool active cooling system maintains chamber temperatures between 15–30 °C during high-intensity irradiation, enabling realistic thermal management comparable to ambient retail or storage conditions; system is removable for standard climate aging tests up to 70 °C.
• Independent, simultaneous control of Black Standard Temperature (BST), Black Panel Temperature (BPT), and Chamber Temperature (CHT), with configurable tolerances for each parameter to ensure test fidelity across dynamic cycles.
• Direct irradiance setpoint control at 340 nm (0.26–0.62 W/m²) and broadband 300–400 nm (30–65 W/m²), traceable via optional SunCal BB 300–400 sensor calibration kit compliant with ISO/IEC 17025-accredited practices.
• Ultrasonic humidification system provides precise RH modulation when SunCool is disengaged; integrated 60 L spray reservoir supports programmable water spray cycles (25–70 °C) with 5° sample plane tilt for uniform runoff and surface wetting.
• 7-inch capacitive touchscreen interface with 13 language options, intuitive icon-driven navigation, and built-in diagnostics—including lamp life tracking, filter degradation alerts, and real-time fault logging.

Sample Compatibility & Compliance

The SUNTEST XXL+ FD supports diverse sample geometries—including rigid containers, flexible films, powder formulations (via optional ICH-D10/20/30 powder holders), and multi-layer laminates—without requiring sample miniaturization. Its open-access design includes a 30 × 25 mm feedthrough port for integration of external sensors (e.g., oxygen permeability probes, surface temperature arrays). All BST sensor configurations conform to ISO 4892-1 mechanical and thermal specifications, ensuring metrological consistency across laboratories. The chamber meets key international standards for photostability testing: ISO 4892-2 (xenon arc exposure), ASTM G155 (non-metallic materials), IEC 60068-2-9 (sunlight simulation), and ICH Q1B (photostability testing of new drug substances and products). Its architecture facilitates GLP-compliant operation through audit-trail-capable data logging and user-access-level controls.

Software & Data Management

Internal flash memory stores all test parameters, sensor readings, and event logs with timestamped resolution. Data export is supported via USB memory card or RS232 serial interface in CSV format for post-processing in LIMS or statistical analysis platforms. Optional XenoTouch software extends functionality with three modular add-ons: “Remote Control” (secure web-based test initiation and parameter adjustment), “Email Service” (automated notifications upon test completion or alarm triggers), and “Online Monitoring” (real-time dashboard visualization of irradiance, BST, CHT, and humidity trends). All communication protocols are compatible with enterprise IT security policies, and data integrity is preserved through write-protected storage and non-volatile memory backup.

Applications

This instrument is routinely deployed in R&D and QC laboratories for photostability assessment of food contact materials, beverage bottle labels, pharmaceutical blister packaging, cosmetic containers, and automotive interior trim. Its capacity to replicate supermarket fluorescent lighting spectra—combined with precise thermal-hygrometric control—makes it uniquely suited for evaluating color fade, gloss loss, embrittlement, and chemical migration under simulated shelf conditions. In accelerated shelf-life testing (ASLT), the SUNTEST XXL+ FD enables predictive modeling of product degradation kinetics over days rather than months, supporting rapid formulation iteration and regulatory dossier preparation. It is also widely adopted in academic research on polymer photooxidation mechanisms and UV stabilizer efficacy screening.

FAQ

What standards does the SUNTEST XXL+ FD comply with?
It conforms to ISO 4892-1/-2, ASTM G155, IEC 60068-2-9, and ICH Q1B for photostability testing.
Can the chamber operate without the SunCool system?
Yes—the SunCool module is field-removable, allowing conventional high-temperature climate aging up to 70 °C.
Is humidity control available during high-irradiance testing?
Ultrasonic humidification is disabled when SunCool is active; however, condensation-free chamber insulation prevents moisture accumulation regardless of operating mode.
How is irradiance calibrated and verified?
Using the optional SunCal BB 300–400 sensor kit, which provides NIST-traceable calibration for both irradiance (W/m²) and BST (°C) across the 300–400 nm band.
What sample mounting options are available for powders or small-dose pharmaceuticals?
The ICH-D10/20/30 powder sample holders accommodate 1–3 mm particle layers and are designed for compliance with ICH Q5C and Q1B guidance documents.
