RDR-350 Rotating disk reactor

The RDR-350 is designed to facilitate studies on the reaction rates between various fluids and solid surfaces. The device features a rock disk that spins at a fixed speed within a sealed chamber filled with reactive fluid. The degree of mass transfer and chemical reactions can be modulated by adjusting the rotational velocity and the temperature of the experiment. Fluid samples, which include products of the chemical interaction between the rock and fluid, are collected at predetermined intervals. Concentrations of calcium or magnesium in these samples are then quantified using atomic absorption spectrophotometry. The overall reaction rate at a specific angular speed is calculated based on the change in reactant concentration over a set period. To gather data on the reaction rate relative to angular velocity, the experiment is replicated at varying speeds. Further tests can be conducted at different temperatures or with altered fluid concentrations to fully establish the rate law governing the reaction system.
