Scalable Pulse-flow photoreactor for feasibility studies and screening
The Oscillating Flow-Photoreactor series is built on a proprietary technology. This patented technology for continuous operation stands out from all known designs and functions by its unique technology and allows to implement flow-photochemistry from the early discovery phase (ml scale) and seamlessly scale it throughout the process development stage up to commercial production of several metric tons per annum. The reactor design of the pulse flow photoreactor for feasibility studies and screening allows a single-technology scale-up strategy, and the low pressure drop makes high-throughput operations feasible. With this technology, production scale flow-photochemistry is now commercially available.
This oscillating flow photoreactor is part of our MPDS®BASIC system designed for feasibility studies and photochemical screening.
Our oscillating flow photoreactor is a laboratory scale photoreactor with a volume of 5 ml, which has a reactor base with integrated heat exchanger. This enables the operation of (photo)chemical processes under isothermal conditions.
Built into the reactor base is the modular process inlay system, giving you the ultimate flexibility to customize the reactor to your chemistry. Interchangeable ports and inlays are available in a variety of different materials and patterns for static mixing elements.
The process channel is covered by a large transparent window that allows for efficient irradiation or visual inspection and PAT methods. The assembly consists of a fully functional reactor unit equipped with inlet ports and a process insert. The integrated light module novaLIGHT HLED 25 with an output of 25 watts is dimmable and available with different wavelengths that can be easily exchanged.
