BS-03 irradiation chamber for multiple samples per run
The BS-03 is a medium-sized, rugged irradiation chamber for time- or dose-controlled irradiation of samples with UVA, UVB, or UVC. The chamber can be fully equipped for one of the spectral ranges UVC, UVB, or UVA to achieve the highest irradiance – 10 mW/cm² in UVC, 2 to 4 mW/cm² in UVB and 8 mW/cm² in UVA or UVA+. Alternately, the use of two separately controlled lamp groups for different spectral ranges allows for especially flexible operation of the chamber.
The interior irradiation chamber has a base area of 68 × 49 cm² and a height of 32 cm. The sliding sample carrier facilitates loading and unloading. The carrier supports loads of up to 20 kg. 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.
Two irradiation controls are available for the BS-03: the UV-MAT and the UV-MAT Touch. Both controllers enable separate control of two spectral ranges and ensure a constant dose, regardless of lamp ageing, contamination or temperature. The dose is measured using calibrated sensors that include a precise analog-to-digital converter and a temperature sensor.
The UV-MAT Touch user interface is a high-resolution capacitive touchscreen. New functions can be installed on site via firmware update. The UV-MAT Touch and the PC software are Windows 10/11 compatible.
Numerical and graphical single and multi-channel irradiations, oscillograms and the settings are clearly displayed. Parameterization is performed intuitively directly on the UV-MAT Touch and is password protected.
The UV-MAT Touch also records the irradiations and can be controlled by the PC. This makes multi-stage irradiations and the documentation of the irradiation possible.
Calculate irradiance and dose of the BS-03
Set up the BS-03 virtually in advance:
Calculate irradiance, uniformity and exposure time for UVA, UVB and UVC.
Simulate the irradiance distribution of the BS-03 in 3D
How the irradiance is distributed across the 60 × 45 cm sample tray of the BS-03 is shown by the UV irradiation chamber simulator before the experiment. It calculates a heat map and cross-sectional profile for every measurement plane between the floor and the 20 lamps and provides the exposure time required for a target dose.
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-03 spreads 20 lamps over an interior of 68 × 49 × 32 cm; the irradiance it reaches is given in the technical data below.
Equipment in detail
The BS-03 has a modular design and can therefore be adapted to different applications. These functions are always part of the scope of delivery:
  | 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
Every irradiation chamber can be equipped with different options. For cell and virus irradiation and other laboratory applications the UV-MAT Touch dose control and attenuators are often combined; this gives 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. |
