OVERVIEW:
GWSI Adapter Socket with Glass Stopcock is built for precise on/off flow control in reaction, vacuum, transfer, and distillation assemblies. Made from premium borosilicate 3.3 glass, it delivers high thermal shock resistance, strong hydrolytic resistance, and excellent chemical inertness. Manufactured by GWSI Glass Lab in Ambala, Haryana, India, it offers a clean, reusable, and leak-resistant connection for demanding laboratory work.
HISTORY :
Glass stopcock adapters became widely used as ground-glass joints were standardized in the early 20th century. They solved the need to control liquid or gas flow directly within glass assemblies without adding bulky external valves.
APPLICATIONS :
* Used in pharmaceutical labs for controlled reagent addition, vacuum isolation, and solvent transfer.
* Suitable for biotech workflows needing autoclavable lab glass with clean flow shut off.
* Applied in industrial laboratories for distillation, gas handling, filtration, and process testing setups.
MANUFACTURING PROCESS :
GWSI manufactures each adapter by melting high-purity borosilicate 3.3 glass and shaping the socket body, stopcock barrel, and flow path through master hand-blowing or precision automated molding. The finished piece is annealed in a controlled furnace to relieve thermal stress and support stable performance during repeated heating and cooling.
TESTING PROCESS :
Each adapter is checked through a polarization stress test using a Polariscope to verify zero residual stress and dependable glass integrity
PACKAGING PROCESS :
Finished adapters are cosmetically sorted to remove pieces with blemishes, uneven sockets, chipped rims, or poorly seated stopcocks. Each unit is packed in heavy-duty double-wall boxes with shock-absorbing bubble wrap for safe export handling.
MAINTENANCE & SAFETY :
* Clean with neutral lab detergent, rinse well, and dry the stopcock bore before storage.
* Autoclave only with the stopcock open or loosened to prevent trapped pressure.
* Store padded and lightly separated to protect the socket, plug, barrel, and ground joint surface.
