The Q-Lab Q-SUN Xe-1-SCE Tabletop Xenon Arc Test Chamber with Water Spray and Chiller is a compact xenon arc weathering tester for laboratories that need controlled full-spectrum light, direct spray exposure and lower temperature capability in a benchtop format. The Xe-1-SCE model combines a tabletop flat-array chamber, one 1800 W full-spectrum ozone-free xenon arc lamp, SOLAR EYE irradiance control, water spray and a chiller-supported chamber base. It is designed for technical buyers testing plastics, coatings, textiles, packaging, printed materials, sealants, cosmetics, pharmaceuticals and smaller product samples where sunlight, rain and controlled lower-temperature exposure must be simulated under repeatable laboratory conditions. For laboratories comparing Q-SUN Xe-1 models, the Xe-1-SCE is the Spray + Chiller Model E configuration, providing more capability than Xe-1-SE where lower chamber air temperature or lower black panel temperature conditions are required.
Test Standards Supported
The Q-SUN Xe-1-SCE supports xenon arc weathering and lightfastness methods where the selected cycle requires irradiance, temperature control, water spray and chiller-supported lower temperature capability. Because this model does not include relative humidity control or water immersion, the exact test cycle should be reviewed before purchase to confirm that the Xe-1-SCE configuration matches the method requirements.
- ASTM G155, xenon arc exposure of non-metallic materials, where the selected cycle suits the Xe-1-SCE configuration.
- ISO 4892-2, plastics exposed to laboratory xenon arc light sources, subject to filter and spray cycle requirements.
- ISO 16474-2, paints and varnishes exposed to laboratory xenon arc light sources, subject to cycle requirements.
- ASTM D2565, xenon arc exposure of plastics intended for outdoor applications.
- ASTM D6695, xenon arc exposure of paints and related coatings, subject to the selected exposure cycle.
- AATCC TM16 and AATCC TM169, textile lightfastness and weathering methods where the cycle is compatible.
- ISO 105-B02 and ISO 105-B04, textile colour fastness methods, subject to filter and exposure requirements.
- ICH Q1B photostability workflows where the exposure conditions align with the Xe-1-SCE configuration.
Configuration Notes
- This Xe-1-SCE model is the Spray + Chiller configuration of the Xe-1 tabletop chamber.
- This model includes front water spray for rain and moisture exposure cycles.
- This model includes a chiller for lower black panel, insulated black panel and chamber air temperature operation.
- This model does not include relative humidity control.
- This model does not include water immersion. Water immersion is specific to the Xe-1-WE configuration.
- Xe-1 controls either BP/IBP temperature or chamber air temperature, but not both at the same time.
Key Features
- Compact tabletop Xe-1 format with spray and chiller capability for more demanding small-scale xenon arc testing.

Specimen Capacity and Configuration
The Q-SUN Xe-1-SCE provides a 22 x 42 cm specimen area and supports 15 specimens at 51 x 102 mm. The flat-array format and 10° specimen orientation are suitable for lightfastness, colour change, gloss retention, yellowing, cracking, fading and comparative material screening. Q-Lab notes that Xe-1 specimen capacity is shown without specimen holders, so holder selection should be confirmed during configuration.
The key advantage of the Xe-1-SCE is that it combines spray and chiller capability in the compact Xe-1 platform. Compared with Xe-1-SE, it adds lower temperature operation. Compared with Xe-1-BCE, it adds water spray. This makes it useful where the laboratory needs direct moisture exposure but must also avoid excessive sample temperature during light exposure, especially for heat-sensitive plastics, coatings, adhesives, textiles, packaging films or printed materials.
Operating Specifications
The Xe-1-SCE is an S model, so it requires higher-purity water than non-spray Xe-1 configurations. Q-Lab lists the water requirement for S or W models as inlet pressure of 2.1 to 6.2 bar, resistivity greater than 5 MΩ.cm, conductivity less than 0.2 μS/cm, total dissolved solids less than 0.1 ppm and colloidal silica less than 0.1 ppm. Q-Lab also recommends pH 6 to 8 and use of a reverse osmosis/deionisation system for S models.
For installation planning, the combined Xe-1 and chiller dimensions are 78 x 138 x 79 cm, and the listed weight is 124 kg. The electrical requirement is 208 V 1-phase at 19 A or 230 V 1-phase at 16 A, with voltage tolerance of plus or minus 10% and 50/60 Hz operation. Q-Lab’s recommended laboratory ambient condition is 23 ± 5 °C and 50 ± 25% relative humidity, and the chamber should not be operated above 36 °C ambient or above 80% RH.
Why Choose the Q-Lab Q-SUN Xe-1-SCE?
The Q-Lab Q-SUN Xe-1-SCE is a strong choice for laboratories that need compact xenon arc testing with both direct water spray and lower temperature capability. Compared with Xe-1-BE, it adds spray and chiller capability. Compared with Xe-1-SE, it adds chiller-supported lower temperatures. Compared with larger Xe-2 and Xe-3 chambers, it provides a smaller footprint and simpler installation for laboratories with moderate sample throughput.
For technical buyers, the main commercial value is focused capability in a compact system. The Xe-1-SCE combines full-spectrum xenon exposure, water spray, chiller-supported temperature control, SOLAR EYE irradiance control, AUTOCAL calibration, Model E touchscreen operation and standard datalogging in one tabletop chamber. This supports repeatable weathering, photostability and lightfastness testing for quality control, R and D screening, formulation comparison and supplier qualification work.
