Collimated Beam Device BSM-03 CBD

The irradiation chamber BSH-02 is a high-powered UVC chamber with superior irradiance of 85 mW/cm². Like all BS irradiation chambers, the BSH-02 offers time- or dose-controlled irradiation of samples with UV light. The chamber is fully equipped with ozone-free UVC amalgam lamps with a total lamp power of 750 W. Compared to our standard BS series, the BSH-02 offers irradiance that is 750% higher. Thus, the irradiance is high enough for high-energy applications or UV curing. The BSH-02 has compact outer dimensions and the interior irradiation chamber has a base area of 46 x 32 cm and a height of 25 cm. The sample chamber operating temperature is about 45°C so that thermal damage to the specimen is minimized. Due to the high uniformity of the irradiation, the samples may be positioned in any order.

The UV LED chamber BSL-04 is the largest irradiation chamber in the BSL series. The high irradiance combined with the exact dose control offers a unique reproducibility for perfect results! The wavelengths 365 nm, 385 nm, 395 nm, 405 nm and 450 nm are available for your application. Due to the irradiance of up to 110 mW/cm² and the high homogeneity, even very large parts or batches can be irradiated. For high irradiances, the UV LED chamber can be ordered completely with one LED wavelength. A particularly flexible application is possible when two separately controllable LED wavelengths are ordered. Compared with our irradiation chambers of the BS series, the BSL-04 offers an irradiance that is 14 times as high. The high irradiance allows for extremely short exposure times. With the high homogeneity of the irradiation, the samples can also be positioned as needed.

The BS-02+ is a compact irradiation chamber for performing photostability tests according to ICH Q1B and VICH GL5 for medical products and active pharmaceutical ingredients. Irradiation is performed with UVA radiation and visible light according to option 2 of the ICH Q1B guideline. With a footprint of 46 x 32 cm and a height of up to 20 cm, the irradiation chamber provides space for samples. The 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 specimens can be positioned as desired. In accordance with the ICH Q1B guideline, modern LED light sources with a „Cool White“ emission (ISO 10977) and UVA fluorescent lamps are used. The UVA fluorescent lamps emit a maximum between 350nm and 370nm.

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.
