Features
Stable Water-Cooled Source: The 2.5kW water-cooled system manages the thermal load of the xenon lamp more efficiently than air-cooled alternatives, providing superior spectral stability and longer lamp life.
High-Temperature Capability: You can achieve a Black Panel Temperature (BPT) of up to $110^{\circ}\text{C}$, allowing for the simulation of extreme heat conditions found in automotive interiors or tropical outdoor environments.
Large Throughput for Compact Size: Despite its manageable footprint, the GX25 can accommodate up to 108 specimens simultaneously, making it ideal for high-volume batch testing.
Precise Dark Cycle Simulation: The system allows you to transition to a high-humidity dark mode ($95\%\text{ RH}$), effectively simulating nighttime dew and moisture absorption.
Customizable Spectrum: By utilizing specific filter combinations like the #295 outer filter, you can tailor the UV cutoff to match specific outdoor or indoor sunlight conditions.
Accessories
Xenon Burner: Replacement 2.5kW water-cooled xenon arc lamp.
Filter Sets: Various inner and outer filters (e.g., #295. #320. Quartz) for spectral adjustment.
Specimen Holders: Stainless steel clips designed for standard $65 \times 55\text{ mm}$ samples.
Black Panel Thermometer (BPT): Integrated sensor for accurate surface temperature monitoring.
Cooling Water Unit: Deionizer and heat exchanger system for lamp cooling.
FAQ
1. What types of materials are best suited for testing with the GX25?
The GX25 is ideal for plastics, textiles, coatings, electronic components, packaging materials, and automotive interior parts that require controlled lightfastness and weather resistance evaluation.
2. How does water cooling improve test stability compared to air-cooled systems?
Water cooling more effectively removes heat from the xenon lamp, resulting in improved spectral stability, longer lamp life, and more consistent irradiance over extended test durations.
3. Can the GX25 simulate both daytime and nighttime environmental conditions?
Yes. The system supports programmable light and dark cycles, including high-humidity dark phases that simulate nighttime dew and moisture absorption.
4. How do filter selections affect test results?
Different filter combinations adjust the UV cutoff and spectral distribution, allowing you to replicate outdoor sunlight, window-filtered indoor light, or enhanced UV exposure depending on your test objective.
5. How is uniform exposure ensured when testing a large number of samples?
The rotating specimen rack and centralized xenon light source ensure that all samples receive uniform irradiance and consistent thermal conditions.
6. Is the GX25 suitable for standard compliance testing?
Yes. When configured correctly, the GX25 supports ISO, ASTM, AATCC, and JIS test methods commonly used for lightfastness and weathering evaluations.
