PearlLab Beam™

Each bacteria, virus or spore has a unique sensitivity to ultraviolet light. Accurate determination of exposure times and wavelengths is a key step in characterizing cell behavior for any researcher or system designer. Collimating Beam Devices are a critical tool in providing a standardized unit of measurement for UV exposure.

Historically, these devices have used mercury-based lamps resulting in expensive, cumbersome, difficult to operate, and potentially dangerous systems. PearlLab Beam, from AquiSense Technologies, is a compact Collimated Beam Device which employs UV LEDs and emits radiation in the germicidal range. Its small size and ease of use allows the realization of a tabletop homogenized UV delivery system which can be operated in virtually any laboratory or field locations. The PearlLab Beam features a narrow band emission and is available in a suite of individually addressable wavelengths without the use of filters. As full UV-C intensity is reached in under 10mS, the use of a shutter is not necessary.

PearlLab Beam™ | UV Dose Response Tool

Each unit provides a very uniform and stable irradiation spot with a Petri Dish Factor above 0.9. They can be used to uniformly irradiate Petri dishes up to 60mm in size. A proprietary integrated heat management system guarantees constant irradiation as a function of time. The temperature of each UV-LED is controlled with active feedback to ensure the intensity output remains constant. This prevents instant decay after turning on, which is typical of commercial UV LED sources. With UV-LED lifetimes up to 10,000 hours of constant wave operation, the PearlLab Beam requires no consumables.

The PearlLab Beam consists of a UVinaire, controller and collimating tube. Operation is extremely simple; place the Petri dish under the collimator tube, switch-on the desired wavelength(s) and expose the sample for a given time. Separate Intensity measurements can be made to calculate the UV Dose.

Far smaller and easier-to-use than mercury lamp-based collimated beam devices, the PearlLab Beam is an ideal addition to any laboratory working with UV Disinfection.
