This apparatus is designed for demonstration and laboratory experiments to illustrate how various external factors—such as temperature, reagent concentration, pressure, and catalysts—influence the rate of chemical reactions. The set includes a 160 x 220 mm stand and two 20 mm diameter Landolt vessels equipped with rubber stoppers. Depending on the specific configuration, the unit may also feature reagent containers, replaceable heating elements, stirrers, thermometers, and timers or other auxiliary tools for precise reaction time measurement.
