Inert UV-LED chamber BSL-01i

The BSL-01i is a compact UV LED irradiation chamber for curing and bonding under inert conditions. Within an interior of 20 × 20 × 20 cm it reaches an irradiance of up to 800 mW/cm² using modern UV LED technology – 80 times the irradiance of our classical irradiation chambers. As a tabletop unit it is classified in group 0 according to DIN EN 12198 and is suitable for laboratories and manufacturing.

For different applications, the wavelengths 365 nm, 385 nm, 395 nm, 405 nm and 450 nm are available. Optionally, two wavelengths can be controlled separately. This means that the irradiation chamber can be perfectly adapted to the photoinitiator‘s requirements and is ideal for laboratory use or product changes.

A nearly airtight design with separate gas inlets and outlets allow irradiations under inert conditions. For this purpose, we recommend using nitrogen as a scavenging gas with a slight overpressure. The measurement of the O2 concentration can be optionally performed at the rear gas outlet for this purpose.
The irradiance is adjustable from 1% to 100%. The integrated timer controls the irradiance precisely.
For even better results, we recommend one of our calibrated UVA+ sensors.

The dose control is already integrated in the UV-MAT Touch and UV-MAT control units in the BSL-01i UV LED chamber. By means of an optional sensor, the UV-MAT measures the irradiance continuously, and stops the irradiance at the set target dose.

Due to the free adjustability of the irradiance and the exposure time, the optimum parameters can be determined reliably.

We offer the BSL-01i with three irradiances:

• 0 to 800 mW/cm² (version HO)
• 0 to 400 mW/cm²  (version ECO)
• 0 to 200 mW/cm²  (version ECO+)

Due to the low heat input of the UV LEDs, thermal damage of the samples is minimized. A heating/cooling plate is optionally available for sample temperature control.

In the completely closed and monitored irradiation chamber, the operating personnel are fully protected from the UV radiation.
