Iron ring is used in the laboratory together with iron stand and gauze to support containers such as beakers, evaporating dish, flasks, etc. Iron ring should be removed from the iron stand immediately after use in order to prevent the spillage of the chemical substance that was heated on the ring. Removing the iron ring will ensure that the heated chemical was removed from the ring and put in the appropriate corner. Removing the ring will also reduce the probability of getting injured from the heated ring.
