ASTMAmber PrintingBorosilicate glass 3.3 is highly resistant to water effects, neutral and acid solutions, heavy acids and their mixtures, to chlorine, bromine, iodine and organic compounds. Even in long-term effects and at temperatures above 100 °C, this glass outstrips with its chemical durability most metals and other raw materials. Class of Resistance to Acid Effects (ISO 1776 a DIN 12116) is Class S1.Classes of volumetric glassware are designations derived from applicable standard indicating the relative tolerances. Class A volumetric glassware have higher accuracy with tighter tolerance as compare to Class B volumetric glassware.
