UV irradiation chamber BS-02

The irradiation chamber BS-02CT is a chamber to test samples according IEC 60335-1: “Household and similar electrical appliances – Safety – Part 1: General requirements - Edition 5.2” This test is designed for non-metallic materials that are exposed to direct or reflected UVC radiation from 200 nm to 280 nm. The test can be used to test radiation stability against UVC radiation that can cause aging like discolorations, changes in material properties, crack formation and smell. Therefore the UVC low pressure mercury lamps emit a continuous spectral irradiance of 10 W/m² at 254 nm. IR heater heat up the samples so that a black-panel temperature of 63 °C ± 3 °C can be reached and controlled. The time can be set to an exposure duration of 1000 h. The irradiation chamber BS-02CT can also be used to test material properties that are disinfected by UV-C. Typically the UVC dose of a daily disinfection for a period of two years can be accelerated to 12 hours.

With the UV LED chamber BSL-02, we offer you a versatile irradiance chamber on a basis of high quality UV LEDs. The most common UV curing adhesives can be applied, due to the high irradiance of 400 mW/cm². Compared to our irradiance chambers of the series BS, the series BSL-02 offers the 40-fold irradiance. In addition, the high irradiance allows for very short exposure times. With the typical UV LED characteristics like „Instant-Start“, the dimmability and the long service life, the BSL-02 is ideal for laboratory tests and the manual production. The irradiance is adjustable from 2% to 100%. The integrated timer controls the irradiance precisely. For even better results, we recommend one of our calibrated UVA+ sensors. The dose control is already integrated in the UV-MAT Touch and UV-MAT control units in the BSL-02 UV LED chamber.

The UV test chamber BS-04 is large, robust equipment for the time- or dose-controlled irradiation of samples with UV light. The chamber can be fully equipped for one of the spectral regions UV-C, UV-B, or UV-A to achieve the highest irradiance. Alternately, the use of two separately controlled lamp groups for different spectral regions allows for especially flexible operation of the chamber. The interior irradiation chamber has a base area of 86 x 65 cm² and a height of 32 cm. The sliding sample carrier facilitates loading and unloading. With a load of up to 20 kg, this can withstand all demands. The sample chamber operating temperature is about 25°C so that thermal damage to the specimen is avoided. Due to the high uniformity of the irradiation, the samples may be positioned in any order. The BS-04 can be equipped with two irradiation controls: the UV-MAT and the UV-MAT Touch.

The 3D UV test chamber BS-05 is a large irradiation chamber for double-sided, 3D irradiation of samples with UV or visible light. A sample plate made of stainless steel or fused silica or a rotating holder for mixing of fluids are available. Like all BS irradiation chambers, the BS-05 offers time- and dose-controlled irradiation of samples with UV light. The chamber can be fully equipped for one of the spectral ranges UVC, UVB, or UVA to achieve the highest irradiance. Alternately, the use of two separately controlled lamp groups for different spectral ranges allows for especially flexible operation of the chamber. The large irradiation chamber of the test chamber has a base area of 86 x 65 cm² and a height of 32 cm. The maximum sample chamber temperature during operation is approx. 25 °C, so that thermal damage to the samples is avoided. Due to the high homogeneity of the irradiation, the samples can be positioned as required.
