Permeation lab - Essay ExampleOur experiment dealt with fetching PDMS devices and also foc utilize 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 cardinal 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 toilet 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 wont leak from the battery.The materials used to complete this experiment are test tubes, aluminum foil,30G syringe, Tygon tubes, Deionized no crest water ,pipet, Rhodium-B, Mineral Oil, Sudan red Dye, Ruler no cap, PDMS, Curing no cap solution, Scalpel no cap, cover slides Empty 20G spray 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 sidePermeation is necessary in the context of understanding the carry 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
