Boro 3.3 or Borosilicate 3.3 is a type of glass having very low coefficient of thermal expansionwhite 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.

Glass Stopcocks regulate the flow of liquids or low pressure gases & serve many functions in the laboratory. Glass stopcocks with ground glass key are preferable for use at higher temperatures.
