藥物成份 Spotechem E-Plate is a complete disposable electrode which measures Na+, K+, and Cl- simultaneously. Its reactive portion is made up of two layers: the first layer is formed by an ion selective membrane and underneath this is a silver/silver chloride layer as base electrode. On the surface of plate, there are a sample well, a reference solution well, probe-contact holes where a potential formed on each of Na+, K+, and Cl- electrodes is measured, and air bleeding holes. @ 藥要看
