Boro 3.3 or Borosilicate 3.3 is a type of glass having very low coefficient of thermal expansion white ceramic colours used for white printing on glassware's. white ceramic colours are cured at high temperature & are durable, permanent, excellent weatherability, surface hardness and chemical resistance. Borosilicate 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. PE Stopper diamond graduated line
