The Q-Lab Q-SUN Xe-1-SE Tabletop Xenon Arc Test Chamber with Water Spray is a compact xenon arc weathering tester for laboratories that need controlled full-spectrum light, temperature and direct spray exposure in a benchtop format. The Xe-1-SE model combines a tabletop flat-array chamber, one 1800 W full-spectrum ozone-free xenon arc lamp, SOLAR EYE irradiance control and water spray capability. It is designed for technical buyers testing plastics, coatings, textiles, packaging, printed materials, sealants and smaller product samples where sunlight, heat and rain exposure need to be simulated under controlled laboratory conditions. For laboratories comparing Q-SUN Xe-1 models, the Xe-1-SE is the Spray Model E configuration, offering more moisture capability than Xe-1-BE while avoiding the chiller hardware of Xe-1-SCE and the water immersion system of Xe-1-WE.
Test Standards Supported
The Q-SUN Xe-1-SE supports xenon arc weathering and lightfastness methods where the selected cycle requires irradiance, temperature control and water spray. Because this model does not include relative humidity control, chiller operation or water immersion, the exact test cycle should be reviewed before purchase to confirm that the Xe-1-SE configuration matches the method requirements.
- ASTM G155, xenon arc exposure of non-metallic materials, where the selected cycle suits the Xe-1-SE 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 spray and chamber conditions match the laboratory method.
Configuration Notes
- This Xe-1-SE model is the Spray configuration of the Xe-1 tabletop chamber.
- This model includes front water spray for rain and moisture exposure cycles.
- This model does not include relative humidity control.
- This model does not include a chiller. For spray plus chiller, review Xe-1-SCE.
- 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.

Specimen Capacity and Configuration
The Q-SUN Xe-1-SE provides a 25 x 46 cm specimen area and supports 17 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 difference between Xe-1-SE and Xe-1-BE is the water spray function. This makes the Xe-1-SE more suitable where the test cycle needs direct moisture exposure in addition to light and temperature. If the laboratory needs lower chamber air temperature capability, the Xe-1-SCE should be reviewed. If the method requires water immersion rather than spray, the Xe-1-WE should be reviewed. If the method requires full relative humidity control, a Q-SUN Xe-2 or Xe-3 humidity configuration is more appropriate.
Operating Specifications
The Xe-1-SE 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 Xe-1-SE external dimensions are 78 x 52 x 65 cm, and the listed weight is 50 kg. The electrical requirement is 208 V 1-phase at 12 A or 230 V 1-phase at 11 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-SE?
The Q-Lab Q-SUN Xe-1-SE is a strong choice for laboratories that need compact xenon arc testing with direct water spray. Compared with Xe-1-BE, it adds spray exposure for more realistic rain and moisture simulation. Compared with Xe-1-SCE, it avoids the added chiller system where lower temperature operation is not required. 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-SE combines full-spectrum xenon exposure, water spray, 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.
