The size of the lamp to be used can be determined by: Choosing the largest lamp which will physically fit in a given reactor, or; Calculating the amount of light energy required to produce product at a desirable rate. The most common reactors used in photochemistry are the stirred-batch and continuous flow.
The tubular photochemical reactor can be operated with one of two light sources, either a high intensity medium pressure metal halide lamp or an LED array. This study is the first to investigate the effect of different wavelength UV radiation in combination with different photo-initiators on the performance of the continuous flow RAFT .

One of the key issues of scaling-up organic photochemistry in an immersion-well (batch) reactor is that light penetration to the surrounding solution is limited by the high absorption of the substrate and falls off rapidly with distance from the lamp.
The "light is off". The bottom chromatogram shows the exact same separation but with the Photochemical Reactor with the "Light On". The difference is obvious. Chromatogram with fluorescence detection of aflatoxins B 1, B 2, G 1, G 2, using photochemical reactor with a) light off and b) light on.
The integration of immersion lamps into agitated photoreactors to perform photochemical reactions may present a high risk of breakage, and such type photochemical reactors has mostly been ruled out in .
The photochemical apparatus PHOTOCHEMICAL MULTIRAYS REACTOR, has been developed thanks to the close cooperation between Helios Quartz R&D dept. and research centers, universities and laboratories for some important scientific tests like: – ICH Photostability tests – Photochemical processes – Photo-Oxidation – Filtered UV radiation Particularly popular in science for its flexibility and .
UV reactor for photochemical processes Special UV lamps with outputs of up to 60 kW are used for photochemical processes. On the one hand, these lamps have specific spectrums and, on the other, they meet the very high demands of the chemical industry. The use of these lamps substantially reduces the explosion risk.

In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a catalyst.In catalysed photolysis, light is absorbed by an adsorbed substrate. In photogenerated catalysis, the photocatalytic activity (PCA) depends on the ability of the catalyst to create electron–hole pairs, which generate free radicals (e.g. hydroxyl radicals: •OH) able to undergo secondary reactions.

UV-PHOTOCHEMISTRY (REACTOR) Some chemical reactions are induced by light and are called photochemical reactions. The absorption of light delivers the energy needed to start the reaction. At IMO, high energy UV light is used to functionalize different carbon surfaces like diamond and carbon nanowalls (a form of few layer graphene).
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 which can be set between -20°C and 80°C. The reactor and lamp are housed in separate, sealed quartz chambers.

A new UV photochemical reactor that employs rapidly interchangeable narrowband excimer lamps has been described. The reactor has been used to establish the most efficient wavelength and conditions for a photoinduced decarboxylative C–C coupling reaction.
UV Protection Photochemical Reactors Ltd offer a number of ways to protect the operator from the dangers of UV radiation. These include heavy duty metal foil to wrap around the areas that emit UV, also screens that block UV radiation, goggles and two part enclosures should ensure that all dangers are eliminated, at the same time giving the .
The first light source made available with the UV-150 photochemical reactor was the medium pressure mercury lamp. This provides constant and precise UV output, with user selectable UV power between 75 W to 150 W – allowing dimmable operation without compromising lamp life or spectral output.

photochemical reactors, the solutions attenuate the light so that irradiation falls off exponentially from the light source. Therefore the efficiency of such reaction units is reduced. Miniaturizing photochemical reactors takes the advantage of the high surface-to-volume ratio and the small length scales of microfabricated devices. At the micro
Assembly and Use of Photochemical Reactor . 1. Disconnect power plug before removing lamp holder from reactor holder. 2. DO NOT EXPOSE EYES TO UV Light. 3. Keep the Photochemical Reactor in a horizontal position to prevent liquid from flowing into lamp connection in case of leaks. 4. Prolonged exposure of reactor coils to UV light causes a .
