The Q-Lab Q-SUN Xe-1-BCE Tabletop Xenon Arc Test Chamber with Chiller is a compact xenon arc weathering tester for laboratories that need controlled full-spectrum light exposure with lower temperature capability. The Xe-1-BCE model combines a tabletop flat-array chamber, one 1800 W full-spectrum ozone-free xenon arc lamp, SOLAR EYE irradiance control and a chiller-supported chamber base. It is designed for technical buyers testing plastics, coatings, textiles, packaging, printed materials, cosmetics, pharmaceuticals and other materials where light exposure must be controlled without adding water spray or humidity functions. For laboratories comparing Q-SUN Xe-1 models, the Xe-1-BCE is the Basic Model E configuration with chiller, making it suitable for light and temperature exposure cycles that require lower black panel, insulated black panel or chamber air temperature capability.
Test Standards Supported
The Q-SUN Xe-1-BCE supports xenon arc weathering and lightfastness methods where the selected cycle can be run with irradiance and temperature control only. Because this Basic configuration includes a chiller but does not include water spray, relative humidity control or water immersion, the exact cycle requirements should be reviewed before purchase.
- ASTM G155, xenon arc exposure of non-metallic materials, where the selected cycle does not require unavailable moisture functions.
- ISO 4892-2, plastics exposed to laboratory xenon arc light sources, where the selected cycle suits the Xe-1-BCE configuration.
- ISO 16474-2, paints and varnishes exposed to xenon arc light sources, where spray and RH are not required.
- ASTM D2565, xenon arc exposure of plastics intended for outdoor applications, subject to cycle requirements.
- ASTM D6695, xenon arc exposure of paints and related coatings, subject to cycle requirements.
- AATCC TM16 and AATCC TM169, textile lightfastness methods where moisture functions are not required.
- ISO 105-B02 and ISO 105-B04, textile colour fastness methods, subject to filter and cycle requirements.
- ICH Q1B photostability workflows where the exposure conditions align with the Xe-1-BCE configuration.
Configuration Notes
- This Xe-1-BCE model is the Basic Xe-1 configuration with chiller.
- This model does not include water spray. For spray plus chiller, review Xe-1-SCE.
- This model does not include relative humidity control.
- This model does not include water immersion. Water immersion is specific to Xe-1-WE.
- Xe-1 controls either BP/IBP temperature or chamber air temperature, but not both at the same time.
- Method suitability depends on filter selection, irradiance control point and temperature requirements.

Specimen Capacity and Configuration
The Q-SUN Xe-1-BCE 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 useful for lightfastness, colour change, gloss retention, yellowing, fading and material screening work where samples can be tested in a compact tabletop chamber. Q-Lab notes that Xe-1 specimen capacity is shown without specimen holders, so holder selection should be confirmed during configuration.
The key difference between Xe-1-BCE and Xe-1-BE is the chiller. The chiller enables lower black panel, insulated black panel and chamber air temperature conditions than the non-chiller Basic model. This is important for temperature-sensitive samples and test cycles where excessive heat could create unrealistic degradation or fail to match the required exposure method.
Operating Specifications
The Xe-1-BCE follows Q-Lab’s non-S and non-W water requirement category. The listed inlet water pressure is 0.7 to 6.2 bar, with water purity greater than 200 kΩ.cm, less than 5 μS/cm conductivity and less than 2.5 ppm total dissolved solids. Q-Lab recommends maintaining pH 6 to 8 for best performance.
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-BCE?
The Q-Lab Q-SUN Xe-1-BCE is well suited to laboratories that need compact xenon arc testing with lower temperature capability, but do not require spray, RH control or immersion. Compared with Xe-1-BE, it adds chiller-supported temperature control for more temperature-sensitive test cycles. Compared with Xe-1-SCE, it keeps the system focused on light and temperature exposure without spray hardware. Compared with Xe-2 and Xe-3 models, it provides a smaller footprint and lower complexity for laboratories with moderate sample throughput.
For technical buyers, the main commercial value is controlled exposure in a compact system. The Xe-1-BCE combines full-spectrum xenon exposure, SOLAR EYE irradiance control, AUTOCAL calibration, Model E touchscreen operation and lower temperature capability in one tabletop platform. This supports repeatable weathering, photostability and lightfastness testing for quality control, R and D screening, formulation comparison and supplier qualification work.
