The Q-Lab Q-SUN Xe-1-WE Tabletop Xenon Arc Test Chamber with Heated Water Immersion is a compact xenon arc weathering tester for laboratories that need controlled full-spectrum light exposure with temperature-controlled water immersion. The Xe-1-WE model combines the Xe-1 tabletop platform, one 1800 W full-spectrum ozone-free xenon arc lamp, SOLAR EYE irradiance control and heated water immersion capability. It is designed for technical buyers testing materials where immersion in water during or between xenon arc exposure steps is part of the degradation mechanism. Typical applications include plastics, coatings, sealants, packaging, adhesives, construction materials and selected product components where light exposure and immersion behaviour need to be evaluated in a controlled laboratory chamber.
Test Standards Supported
The Q-SUN Xe-1-WE supports xenon arc weathering and lightfastness work where the selected method can be performed with irradiance, black panel or insulated black panel temperature control and heated water immersion. Because this model does not include water spray, relative humidity control or chiller operation, the exact test cycle should be reviewed before purchase to confirm that the Xe-1-WE configuration matches the method requirements.
- ASTM G155, xenon arc exposure of non-metallic materials, where the selected cycle suits the Xe-1-WE configuration.
- ISO 4892-2, plastics exposed to laboratory xenon arc light sources, subject to cycle and filter requirements.
- ISO 16474-2, paints and varnishes exposed to laboratory xenon arc light sources, where the cycle is compatible.
- 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 selected exposure conditions.
- 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 and immersion conditions match the laboratory method.
Configuration Notes

Specimen Capacity and Configuration
The Q-SUN Xe-1-WE is intended for exposure programmes where water immersion is required as part of the test cycle. Unlike Xe-1-SE and Xe-1-SCE spray models, the Xe-1-WE is configured around immersion rather than spray. This makes it useful for evaluating materials where submerged exposure, wet contact, swelling, leaching, adhesion loss or immersion-assisted degradation are relevant to the final application.
LX-5046 does not list a separate specimen capacity value for the Xe-1-WE in the operating specification table. For live configuration, specimen holders, immersion tray arrangement and usable sample dimensions should be confirmed at quote stage against the intended method and specimen geometry. This is especially important where the user intends to test thicker samples, mounted assemblies or product parts rather than standard flat coupons.
Operating Specifications
The Xe-1-WE is a W model, so it follows Q-Lab’s water requirement category for S or W models. The listed inlet pressure is 2.1 to 6.2 bar, with water purity 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 the use of a reverse osmosis/deionisation system for best performance.
For installation planning, the Xe-1-WE external dimensions are 99 x 72 x 65 cm and the listed weight is 88 kg. The electrical requirement is 208 V 1-phase at 13 A or 230 V 1-phase at 12 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-WE?
The Q-Lab Q-SUN Xe-1-WE is the correct Xe-1 choice when the test programme requires water immersion rather than spray. Compared with Xe-1-BE, it adds immersion capability. Compared with Xe-1-SE, it changes the moisture simulation from spray to immersion. Compared with Xe-1-SCE, it focuses on heated immersion rather than spray plus chiller operation. This makes it a specialised configuration for laboratories where immersion exposure is a required part of the material durability workflow.
For technical buyers, the main commercial value is matching the chamber to the test mechanism. Materials that perform well under dry light exposure may behave differently when exposed to light and immersion cycles, especially where water contact affects adhesion, swelling, cracking, haze, colour change or chemical extraction. The Xe-1-WE gives laboratories a compact way to run those immersion-based xenon arc evaluations while retaining SOLAR EYE irradiance control, AUTOCAL calibration and Q-Lab’s Model E touchscreen interface.
