Cooperation between Peschl Ultraviolet GmbH together with Hahn-Schickard in Ulm and the University of Ulm

Alexander Peschl, Managing Director of Peschl Ultraviolet GmbH, and Prof. Dr. Dirk Ziegenbalg, Head of the Photochemical Reaction Engineering Group at the Institute of Chemical Engineering at Ulm University, discussed pioneering opportunities for collaboration in the field of photochemistry during their visit to Hahn-Schickard in Ulm. Photoreactors use light energy to initiate chemical reactions, enabling…

PX Parallel Photoreactor

Parallel Photoreactor for Screening

The smallest photoreactor from Peschl Ultraviolet can perform nine irradiation experiments in parallel with very small sample quantities – LEDs are thermally decoupled by means of thermoliquid. The innovative photochemical screening device consists of nine vials (cells), each with a volume of 8 ml, which can be irradiated simultaneously with nine different wavelengths. The intensity…

Agitated Batch Photoreactor

New Agitated-batch photoreactor for scale-up – MPDS® PRO Series

Different photochemical reactions require photoreactors designed for the respective process. In addition to side-loop, falling film and plug or pulsed flow photoreactors, stirred photoreactors play an important role, especially for halogenation / radical reactions as well as multiphase reaction mixtures and large production volumes. Different photochemical reactions require photoreactors designed for the respective process. In…

High power LEDs for photoreactors

For decades, special medium-pressure gas-discharge light sources have been the standard technology used in photoreactors to carry out photochemical reactions. While gas-discharge lamps often have an efficiency of just 5-7% depending on the wavelength, LED light sources offer up to 60% efficiency with high selectivity. However, some obvious technical problems had to be solved, prior…
