Screening Photoreactors for Labs
Screening photoreactors enable rapid, data-driven reaction optimization. Conduct parallel experiments to identify the best irradiation conditions, wavelengths, and intensities, saving time and valuable materials. Precise temperature control and reproducible light output ensure reliable results for feasibility studies, catalyst screening, and early process development. Their flexible, small-volume formats make them ideal for R&D labs working with limited or high-value substrates. From photoredox to photocatalysis, screening photoreactors support fast, informed decisions on the path to series production.
MPDS – Modular Photochemical Development System
From first feasibility tests to precise parameter optimization: The MPDS is your flexible lab-scale photoreactor for batch and flow photochemistry. Its fully modular design allows quick adaptation of light sources, reactors, and process parameters – enabling realistic reaction evaluation before scale-up. Ideal for chemical and pharmaceutical R&D where speed, precision, and scalability matter.
Pilot Photoreactors
Our Pilot Photoreactors are specifically engineered to bridge the gap between laboratory experiments and full-scale production. They provide a controlled environment to validate reaction parameters on a larger scale, ensuring that lab-scale results can be reproduced efficiently in industrial settings. With flexible reactor designs and configurable light sources, pilot systems can mimic both batch and flow processes, supporting optimization of productivity, energy use, and safety.
Industrial-Scale Photoreactors
Industrial-Scale Photoreactors from Peschl Ultraviolet are heavy-duty, ATEX-certified systems designed for large-scale chemical and pharmaceutical production. Available in agitated or falling-film configurations, they are engineered to handle high volumes while ensuring uniform light distribution and reaction efficiency. Each system can be fully customized to match specific process requirements, including batch or flow operations, cGMP compliance, and integration with existing production lines.
Customized Photoreactors for Maximum Efficiency
Beyond our standard photoreactors, we develop application-specific, highly optimized systems tailored to your process needs. Leveraging decades of experience and patented technologies, our custom solutions enhance productivity and profitability. We also support technology transfer, from gas discharge lamps to innovative LED systems, and can convert batch processes to flow setups where technically and economically advantageous.
