UV test chamber BS-05 – double-sided irradiation through a quartz plate
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 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 – 8 mW/cm² in UVC, 4 mW/cm² in UVB, 8 mW/cm² in UVA and 10 mW/cm² in UVA+. This high-performance UV irradiation also covers demanding test tasks with high dose requirements. 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 × 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.
We offer the UV-MAT and UV-MAT Touch irradiation control systems for the BS-05. Both systems control two spectral ranges separately and ensure a constant dose, regardless of factors such as lamp ageing, contamination or temperature. The dose is recorded by calibrated sensors equipped with a precise analog-to-digital converter and a temperature sensor.
The UV-MAT Touch offers a high-resolution capacitive touchscreen for operation. New functions can be installed on site via firmware update. The device and PC software are Windows 10/11 compatible. Numerical and graphical displays of single and multi-channel irradiations, oscillograms and settings are clearly structured. Parameterization is intuitive and password-protected directly on the device.
Alternatively, the UV-MAT Touch can be operated via the PC, which allows multi-stage irradiations and detailed documentation of the irradiation to be carried out.
Calculate irradiance and dose of the BS-05
Set up the BS-05 virtually in advance:
Calculate irradiance, uniformity and exposure time for UVA, UVB and UVC.
Simulate the two-sided irradiation of the BS-05
The BS-05 irradiates from both sides – the UV irradiation chamber simulator models the lamps above and below the sample plane and shows how irradiance and dose are distributed across both sides. Measurement plane, lamp configuration and target object can be chosen freely and the result saved as a simulation report.
The chambers of the BS series are fitted with the same fluorescent lamp types. The spectra shown therefore apply unchanged to the other models – the chambers differ in interior size and number of lamps, and hence in irradiance, not in spectral distribution. The BS-05 carries 40 lamps and irradiates the sample from both sides through the quartz plate; the irradiance it reaches is given in the technical data below.
Equipment in detail
The BS-05 is modular; its equipment can be matched to the application at hand. The following functions are always included:
  | Dose control The irradiance is measured continuously; the UV-MAT ends the irradiation once the set target dose is reached. The UV-MAT Touch offers the same functions but simplifies operation and documentation. |
 | Sensors Suitable materials give the sensors excellent long-term stability. They are traceably calibrated, can be recalibrated and are supplied with a factory or ISO 17025 calibration certificate. Sensors in IP65 as well as further measuring and spectral ranges are available on request. |
 Similar to illustration | Sensor holder The sensor holder fixes two radiometer sensors at the side of the chamber. For measurements on the sample the sensors can be removed, so that the irradiance can be determined at the required position. The UV-MAT can be adjusted to this by a factor. |
 | Control and dimming Two lamp groups can be controlled and dimmed separately - for example four UVA and four UVB lamps. Dimming reduces the irradiance to about 30 %. |
 | Lamps The fluorescent lamps can be changed without tools. We supply the matching lamps for different applications: UVA-352 for UV ageing in indoor applications, UVB lamps for accelerated outdoor applications, UVC for UV disinfection. |
 | Timer As an alternative to dose control the UV-MAT offers an adjustable timer for time-controlled irradiations between 1 s and 999 days. |
 | Irradiation records Irradiations can be recorded with a PC. The UV-MAT Touch also records them to a USB stick without a PC. |
Options
Beyond the basic equipment several options are available. For cell and virus irradiation and other laboratory applications the UV-MAT Touch dose control and attenuators are often used together - for a very uniform and reproducible irradiation. Medical applications benefit from the irradiation documentation that the remote control keeps automatically.
 | Attenuation Attenuators reduce the irradiance to about 30 %. We offer surface attenuators and lamp attenuators - used for example when irradiating cell cultures. |
 | Inert gas box The removable inert gas boxes allow work under inert conditions. Separate gas inlets and outlets make it possible to measure the O₂ concentration at the gas outlet. Available with a top window of high-quality glass for UVA and VIS irradiation or of UV quartz glass for UVB and UVC irradiation. |
 | PC software for the UV-MAT Touch Complex, multi-stage irradiations - for example a pre-irradiation with UVA at low irradiance followed by a high-intensity UVC irradiation - can be parameterised with the remote control option. Up to 30 dose- or time-controlled steps and pauses are possible. At the same time the irradiation is logged and stored on the PC. |
