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.

Needle valve stopcock made form PTFE regulate the flow of liquids or low pressure gases & can be adjusted from a 0 to 6mm bore. this design permits fine flow adjustment, doesn't required Lubrication with fast assembly because there are no O-rings, washers or nuts.
