Azer Scientific Control SLIDE Iron

Azer Scientific Control SLIDE Iron. The color change is attributed to the strong magnetic force between the two glass slides. Therefore slides containing iron must be "chromochromic.". Once exposed to air for an extended period of time an undesirable color change is noticed. The color change is attributed to the coating being applied. The coating on the control slide therefore causes the color change. All slides with iron control areas are to be metallized (reduce the amount of iron exposed to t
