photoLAB - Model Batch-M - 250-400 ml -Mid Volume Photoreactor
The selection of a suitable photoreactor is fundamentally dependent on the requirements of chemical reactions and physical properties of reactants. Using a photoreactor with a low optical path length is necessary, especially for liquids with a molar extinction coefficient of more than 30 m-1. This photoreactor is developed for this purpose. When operating at low process volumes and optical path lengths lower than 2 cm, it is necessary to ensure thorough mixing of the medium. A conventional magnetic stir bar is unsuitable for use in this case because the vortex generated in the annular gap does not allow for the exchange of substances between different levels.
This photoreactor is therefore equipped with an integrated magnetic drive circulation pump, which provides thorough mixing of reactants when used together with a lateral riser pipe. The magnetic drive circulation pump is made of durable and chemically inert materials and can be easily removed from the photoreactor for cleaning. Like all other photoreactors of the MPDS Toolbox, this photoreactor is equipped with a sensor port. Length of reaction times can be freely determined, so that a high yield, close to that at equilibrium, is guaranteed.
The photoreactor‘s high efficiency and simple handling make it a universal standard for use in basic research during a feasibility study.
The MPDSBASIC Set includes the photonCABINET which is a double walled, light-proof protective cabinet made of stainless steel. I fulfills the legal requirements for personal safety agains optical radiation and protects surrounding materials against aging. The photonCABINET it is the only product on the market that meets the high requirements of the applicable standards, is CE compliant and also practicable and functional for operators. The necessary measures implemented for having a safe and functional product are well designed and protected by international patents.
UV radiation is harmful to eyes and skin and can cause irreparable personal injury. Furthermore materials in the ambient exposed to the UV radiation, will undergo an accelerated aging and can be destroyed. Medium pressure radiation sources have a surface temperature of up to 850° C and operate with lethal high voltage. Solvents may not present a explosion hazard for the user. The operation of photoreactors without optical protective device equipped with safety lock (aluminum foil, acrylic glass) is not allowed since the related normative standard was becoming mandatory (01.10.2013). In addition the risk analysis in accordance with EN ISO 12100 confirm, that an operation without safety cabinet is no longer sufficient and does not meet the requirements to protect employees by the owner / operator of the lab, who can be fully accountable and responsible for personal injury.
Therefore photoreactors of the MPDS modular system always come along initially with the light-proof protective cabinet, which moreover provide the electrical power to the electronic power supplies for operating the radiation sources. Photochemical experiments are therefore absolutely safe. The unique photonCABINET is practicable, easy to use and inexpensive to purchase.
