UV test chamber BS-04

The UV test chamber BS-04 is large, robust equipment for the time- or dose-controlled irradiation of samples with UV or visible light. The chamber can be fully equipped for one of the spectral regions UV-C, UV-B, UV-A, or daylight D65 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 64 cm and a height of 25 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 optional UV-MAT irradiation control can separately control two different spectral ranges and obtain a constant dose regardless of lamp aging, pollution, or temperature.

Therefore, calibrated radiometer sensors are used. The integrated diffuser ensures the required cosine correction. Excellent long-term stability is achieved through the use of appropriate materials. The sensors are calibrated with traceability to PTB (Physikalisch Technische Bundesanstalt, the German national test authority); after being calibrated, they are supplied with a factory calibration certificate.

Applications of UV test chamber BS-04

  • Irradiation of bacteria and cell cultures
  • Photo stability testing
  • UV and daylight materials testing
  • UV curing, sealing, and bonding
  • Irradiation with UVA-340 / UVB-313
