PearlLab Beam™: Precision UV-C LED Collimated Beam Device for Laboratory Research
Overview: Revolutionising UV Research with Advanced LED Technology
In scientific research, each bacterium, virus, and spore has a unique sensitivity to ultraviolet light. For researchers and system designers, accurate UV exposure times and wavelengths are essential for understanding cell behaviour and ensuring reliable, reproducible results. The PearlLab Beam™ from AquiSense Technologies meets these critical needs, offering a precise, consistent UV-C LED solution for lab-based UV research across microbiology, material science, and chemical analysis.
Collimating Beam Devices play an essential role in delivering standardised, uniform UV exposure, ensuring that lab results are both reliable and reproducible. Traditionally, these devices relied on mercury-based lamps, which are often cumbersome, costly, and potentially hazardous. The PearlLab Beam™ replaces these systems with a compact, LED-based alternative that delivers precise, stable irradiation in the germicidal UV-C range, making it ideal for benchtop assays in any laboratory setting.
Why Choose the PearlLab Beam™ Over Traditional Mercury-Based Systems?
Mercury-based collimated beam devices come with several drawbacks that make them less suitable for modern laboratory applications. The PearlLab Beam™ overcomes these limitations with a practical, efficient design:
-
Large Space Needed and Limited Portability: Traditional mercury-based systems require significant space and are challenging to store or transport. The PearlLab Beam™ has a compact, ultra-small footprint, easily fitting on any benchtop and offering the portability modern labs need.
​
-
Limited Operational Cycles per Day: Due to thermal restrictions, mercury lamps are limited in the number of times they can be cycled on and off each day. The PearlLab Beam™’s LED technology allows unlimited cycling, enabling researchers to start and stop experiments instantly, maximising lab productivity.
​
-
High Energy Consumption: Mercury lamps consume substantial amounts of energy to sustain UV output. The PearlLab Beam™’s UV-C LEDs use far less energy, providing a more sustainable, cost-effective solution.
​
-
Inconvenient and Costly to Filter: Mercury-based systems typically require filters to achieve desired wavelengths, increasing both complexity and cost. The PearlLab Beam™ achieves narrow-band emissions at up to three wavelengths (255–365 nm) without filters, giving researchers precise control over UV exposure.
Key Features of the PearlLab Beam™: Engineered for Precision and Stability
The PearlLab Beam™ combines AquiSense’s cutting-edge UV-C LED technology with thoughtful design to deliver stable and uniform UV irradiance, making it ideal for laboratory applications:
-
Uniform Irradiation with Superior Stability: Each unit provides a highly stable irradiation spot with a Petri Dish Factor above 0.9, allowing for uniform exposure over petri dishes up to 60mm in diameter. A proprietary integrated heat management system ensures consistent UV intensity over time, preventing the decay in output typical of commercial UV-LED systems.
​
-
Extended LED Lifespan: Designed for longevity, the PearlLab Beam™’s UV-LEDs have lifespans of up to 10,000 hours under constant operation, far exceeding traditional systems and eliminating the need for consumables, which reduces ongoing costs.
​
-
Multi-Wavelength Precision: Researchers can select up to three stabilised wavelengths within a single device for tailored, repeatable results across a range of applications.
​
-
Instantaneous Full-Intensity Output: Achieving full UV-C intensity in under 10 milliseconds, the PearlLab Beam™ eliminates the need for shutters or waiting times, streamlining research workflows.
​
-
Simple, User-Friendly Operation: Operation is straightforward: place the petri dish under the collimator tube, select the desired wavelength(s), and expose the sample. Intensity measurements can also be made to calculate the precise UV dose, supporting the consistency of your research results.
