The image depicts a laboratory experimental setup located in the Medical Physics department of Universitätsklinikum Heidelberg, Germany. The scene is illuminated by natural light from a window overlooking an urban landscape with distant buildings under a clear sky. A prominent AG Draguhn SMT 4 stereo microscope, bearing "Universitätsklinikum Heidelberg" and "Med. Physik" labels, is positioned over a transparent acrylic perfusion chamber. This chamber contains a reddish-brown liquid and a biological sample, identifiable as a green, leaf-like structure resting on a white substrate. Multiple precision mechanical manipulators, one branded "Scientifica," are arranged around the chamber. These manipulators hold delicate probes or electrodes, some of which are inserted into or making contact with the green biological sample. A rectangular white device labeled "CA 700 SENSOR" with a barcode is attached to one of the manipulators. Numerous colored electrical wires (red, blue, yellow, black) and clear tubing connect the various components of the setup. The entire apparatus rests on a light-colored laboratory bench, likely stainless steel. A tall, silver metallic cylindrical post stands vertically on the right side, part of the equipment's support structure. A dark mesh screen is partially visible on the far right. No individuals are present in the frame.
