photoLAB Batch-S - Low volume Photoreactor 10-20 ml. In order to properly perform photochemical reactions with a small amount of liquids, special photo reactors are required. During photocatalysis in particular, the catalyst must be retained in the mixture and should not be removed from the reaction vessel along with solvent. Gas supply plays an essential role (filling the vessel with oxygen or inert gas), and temperature control must be precise. Furthermore, at low lamp output, wavelength-selective radiation and regulation of radiation flux also need to be considered.

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.

photoLAB Batch-L - High volume Photoreactor 400-700 ml. The world’s bestselling batch photoreactor is particularly suitable for carrying out simple basic photochemical research with a product volume of approx. 400-700 ml and is mentioned in many publications. Its simple design makes this photoreactor a universal, flexible standard photoreactor for liquids in which the absorption of the reaction medium is not particularly high and the specific demands on the photoreactor cannot be more closely defined in advance.

The efficient irradiation of liquids with low transmission (optical permeability) represents a hitherto unresolved challenge in some photochemical processes.

It is common knowledge that no one portion of wastewater is exactly identical to any other in terms of composition. For this reason, industrial-scale photochemical treatment of wastewater requires detailed preliminary laboratory investigations, which involve comparing the various photochemical methods available for wastewater treatment and determining the respectively relevant photochemical process parameters. This assessment is mandatory in each individual case.

It is a known fact that no two wasrewaers are of the same composition. The photochemical treatment of wastewater in the industrial sector requires detailed pre-investigation in the laboratory, where the various photochemical processes for wastewater cleaning can be compared and the relevant process parameters established. Without exception, this procedure must be carried out in every single case.

Ready-to-fit module for air conditioning systems with high power lamps. Can be supplied to suit different air flows and applications. This is typo dummy text. You can see from it whether all the letters are there and what they look like. Sometimes words like hamburg fonts, rafgenduks or handgloves are used to test fonts. Sometimes sentences that contain all the letters of the alphabet - these sentences are called "pangrams". This one is very well known: The quick brown fox jumps over the lazy old dog.

Condensate and biofilms result in evaporators to a high bacterial load (e.g. Listeria) which will be spread into the air and are thus passed on to the product. This cross-contamination is a risk for your production with product failures and shorter minimum shelf life. The integration of UVC modules inside and in front of evaporator systems highly reduce the microbial load. Micro-organisms on the surface of the system, as well as in the air are reliably inactivated, and the growth of biofilms in the evaporator will be prevented. The application significantly reduces the airborne microbial load and thus contributing to the air hygiene.

The PUVPRO group of products consists of closed standard systems to handle a range of flows and transmossion regions.(τ). (I am not sure about "regions")

Germ-free conveyor belts and surfaces by using innovative SteriBelt high power disinfection modules. Prevention of cross-contamination, permanent reduction in total germ count on conveyor belts and increase in cleaning intervals between production shifts. Improvements in quality and maintenance and possible extension of sell-by-dates because of disinfected packaging are only some of the benefits to be realised by using the modules.
