The Lab Photo Reactor also provides wireless control of wavelength selection and intensity.

Corning reactors are more durable in corrosive conditions and address a wide range of applications to enable increased efficiency, scalability, yields, and higher quality chemical processing at a much smaller footprint compared to traditional batch reactors.

A photoreactor is a chemical reactor device which brings photons, a photocatalyst, and reactants into contact, as well as collects the reaction products deriving from physicochemical transformations. It can assume different shapes and modes of operation and can be operated in various environments of temperature and pressure. Design a photoreactor means to establish type, mode of operation, size, and optimal operative conditions. Two general types of photoreactors exist such as batch and plug flow: in the first one, the mixing of reacting mixture is favored as high as possible in order to assume a perfectly mixed reactor, while in the second type, mixing is hindered in order to assume a perfectly segregated reactor. With respect to the operation mode, photoreactors are classified in three general types: (i) discontinuous reactor which during the operation does not exchange matter with the ambient; (ii) semicontinuous reactor which exchanges reagents or products with the ambient; and...

The UV-150 photochemical reactor is designed to give safe and accurate heat management as well as the best possible reaction selectivity. It provides a temperature-controlled environment that can be set between -20C and 80C.

The reactor and lamp are housed in separate, sealed quartz chambers. Air is circulated within each chamber to dissipate heat and then separated exhausted from the system. The high flow rate of gas gives effective temperature control. A dichroic mirror further removes heat from the system and reflects more than 90% of UV energy back into the reactor.

The UV-150 reactor is made from a single layer of thin walled, small-bore fluoropolymer tubing. This maximises the absorption of light photons by reagents.

Tubing is constructed into cartridges that can be easily removed and replaced within seconds. Standard reactor cartridges are available in 2ml, 5ml, or 10ml volumes, with smaller reactors advantageous in minimising reagent consumption when optimising reaction conditions. Vapourtec now offers a user rewindable 10ml cartridge. For more information on this please click here (links to the Rewindable reactors tab).

Safety is fundamental in the UV-150 photochemical reactor design. The light source is completely enclosed allowing it to be safely used in a standard laboratory fume cabinet without any additional light shielding.

The power supply to the reactor is interlocked ensuring power is safely and automatically disconnected if the lamp becomes exposed. The forced ventilation system prevents the build-up of flammable gases or vapours.

An international team that includes researchers from the University of Toronto has designed and implemented a new model for photoreactors, a solar-powered technology for converting water, carbon dioxide, methane and nitrogen into greener chemicals and fuels.

Unlike thermoreactors, photoreactors combine the photons in sunlight and reactants to generate green chemicals and fuels. By using sunlight and water, photoreactors could effectively reduce carbon emissions.

Despite their potential, many photoreactors have been plagued by several challenges, including the high cost of construction materials. They can also be inefficient in converting photons to products. To create these photochemical conversions, photoreactors rely on a photocatalyst, a material that absorbs light and converts a reactant into a product.

However, non-productive processes due to the reflection, scattering, transmission and absorption of light by the photocatalyst and the photoreactor materials can result in energy loss. Photoreactors would benefit from sun-tracking, a device that adjusts the angle of the photoreactor with respect to the position of the sun for optimal harvesting of light.

A key feature of their design is that each reaction channel is connected to a V-shaped light-capture unit that guides the light into the channel where the photocatalyst is located. All surfaces are highly reflective to optimize the transport of photons from the external light source to the photocatalyst housed in the microchannels with minimal light losses.

The innovative design allows the photoreactor to capture photons at high efficiency under varying sun directions, eliminating the need for sun-tracking. The panels are also manufacturable via extrusion of polymers, making them inexpensive and easily manufacturable at scale.

Future design adaptations can address the issue of intermittent sunlight by using light-emitting diodes integrated into the photoreactor as the photon source, powered by renewable electricity from photovoltaics and backed up by lithium-ion battery storage to provide 24-7 operations.

The new photoreactors model can outperform existing state-of-art photoreactors and can be used on rooftops of houses and solar farms, as well as be integrated with photovoltaics to produce both renewable electricity and green chemicals and fuels.
