The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase.
