Permeation lab - Essay Example Our experiment dealt with taking PDMS devices and also focused on the study of how water with rhodium-B, ethanol with rhodium-B, isopropanol with rhodium-B (control experiment), and mineral oil with Sudan red react during permeation. However, we were only able to get results from two liquids, water and mineral oil. We observed mineral permeating more than water. We therefore concluded that the study of micro fluids can tell us a lot about making better gasoline, cleaning liquids and other everyday liquids by making sure that liquids whose permeation rates are low are used in such industries. For instance, the battery acid is unlikely to corrode your vehicle if the permeation rate of the liquid used is low and thus the liquid won’t leak from the battery. The materials used to complete this experiment are test tubes, aluminum foil,30G syringe, Tygon tubes, Deionized no cap water ,pipet, Rhodium-B, Mineral Oil, Sudan red Dye, Ruler no cap, PDMS, Curing no cap solution, Scalpel no cap, cover slides Empty 20G Syringe no cap, Ethanol no cap, Timer no cap and Plasma Tray no cap. The Devices no cap needed are Vortex Machine no cap , Vacuum filter no cap, Sonicator no cap, Vacuum no cap chamber, Camera no cap, Microscope no cap and air tank. In figure1 below showing the PDMS device connected with pipet from one side and empty 20G Syringe in another side Permeation is necessary in the context of understanding the flow characteristics of fluids at the microchannel level, since it has been observed that a steady converging flow tends to attain a terminal equilibrium (also called steady-state value) of the permeation constant. Thus, the study of permeation characteristics has been acknowledged as a powerful way to quantify chemical interactions at the center of the channel, where the reaction of the fluid stream would take place. Three test tubes were collected and labeled sample 1, 2
