Opsytec ICH Q1B Irradiation Chamber BS-02

Opsytec ICH Q1B Irradiation Chamber BS-02 is engineered for reliable and compliant photostability testing aligned with ICH Q1B and VICH GL5 guidelines. Designed for medical products and active pharmaceutical ingredients, it delivers controlled UVA and visible light exposure with high uniformity, stable temperature conditions, and automated dose management—supporting precise, repeatable results for regulated environments.

The BS-02+ offers a compact footprint while providing ample space for sample positioning. Its internal temperature remains close to 77 °F (25 °C), helping prevent thermal stress or sample degradation. Thanks to highly uniform irradiance, specimens can be arranged freely without compromising test consistency.

Illumination is achieved with cool-white LED sources (400–700 nm) and UVA fluorescent lamps emitting between 350–370 nm, meeting ICH Q1B and VICH GL5 requirements. Both light sources are dimmable without shifting spectral distribution and automatically shut off once the target dose of 1.2 million LUX-hours and 200 Wh/m² is reached.

The system is compatible with the UV-MAT Touch controller, which monitors UVA and visible light separately for constant dose control, compensating for aging, contamination, or temperature influence. Each sensor integrates a precise A/D converter and temperature sensor, calibrated according to DIN EN ISO 17025 standards. UV-MAT Touch logs irradiance and temperature and enables PC control for streamlined documentation.

The BS-02 features two separate lamp groups that can be controlled and dimmed independently, providing additional flexibility when configuring irradiation conditions. The chamber accommodates up to 8 bulbs and is designed for use with digital sensors.

The UV-MAT Touch irradiation controller features a 5-inch capacitive touch display for intuitive operation, two fully digital sensor connections, and data storage on a USB stick.

Optional PC software for the UV-MAT Touch enables complex, multistage irradiation programs with up to 30 dose- or time-controlled steps. The software also supports logging of the irradiation process on a PC and includes a USB cable and USB stick.

The system can be equipped with RMD sensors for UVA, UVB, and UVC measurements. The quoted sensor options include an RMD Sensor UVA 315–400 nm, 0–1 W/cm²; an RMD Sensor UVB 280–315 nm, 0–1 W/cm²; and an RMD Sensor UVC 200–280 nm, 0–1 W/cm². These sensors are supplied with factory calibration certificates.

Additional available components include mesh filters for lamps, which reduce irradiance to approximately 35%, and an area attenuator, which reduces irradiance to approximately 30%.

Opsytec's measuring instruments are calibrated traceably to PTB standards and are supplied with factory calibration certificates, with DAkkS calibration certificates available as an option. The measuring instruments can be recalibrated, and annual calibration, repair, and spare parts services are available.

Applications include:

• Photostability tests per ICH Q1B
• VICH GL5 testing for veterinary products
• Irradiation of medical products and APIs
