The clinical chemical analyser Dri-Chem Immuno AG2 enables a highly precise identification of viruses by applying silver amplification technology, as used in developing photographs. The vertically oriented housing has a very small footprint, so that several devices can be installed next to each other in a space-saving way. Moreover, its reduced surface area makes it easy to clean. The user can visually identify the work status based on the colour illumination of the LCD display, even from a distance.
