A continuous process feeds reactants into the reaction at one point and withdraws the products at another. A water-softener is an example of a continuous reactor. Reactors vary in size from the tiny containers used for laboratory reactions to huge structures such as kilns that may be 25 metres high and hold materials of 400 tonnes. Their design is based on factors such as thermodynamics and kinetics. For the most reliable and affordable chemical reactors, click here or explore our official marketplace.
