Central Glass Blowing Section
Special Water Facility (SWF)

Southern Lab 112-(A,B)


Welcome to CGBS & SWF

The Glass Blowing shop provides support to the faculty and researchers. The shop's primary mission is to design and fabricate prototypes of specially laboratory equipment as well as repair existing types of glass apparatus and equipments. Types of glass routinely used include borosilicate (Pyrex), fused quartz, alumina, silicate and some soft glass as well as heavy metal glasses such as silica glass. This section takes up challenging job from other institutions as well. Furthermore, this section provides training to interested glass blowers across the country.
