Description
The Socket Adapter with PTFE Needle Valve and Hose Connector, BORO 3.3 Glass, also known as a laboratory needle valve adapter, glass socket stopcock adapter or ground glass hose connector, is designed to connect compatible laboratory glassware with rubber tubing while providing fine control over gas or liquid flow. Manufactured from borosilicate 3.3 glass, the adapter features a female ground glass socket, an integrated PTFE needle valve and a detachable plastic screw-thread hose connector. The PTFE needle valve stopcock provides fine flow adjustment and positive closure, allowing users to regulate the passage of compatible gases or liquids during laboratory procedures. The manufacturer specifies a 3.0 mm nominal bore.
The detachable plastic screw-thread connector allows compatible rubber hoses to be fitted to the adapter, providing a practical connection between jointed laboratory glassware and flexible tubing. A female standard taper ground glass socket connects to a corresponding male joint on laboratory flasks, adapters or other compatible apparatus. Correct joint dimensions are essential for proper assembly. The BORO 3.3 glass construction offers resistance to many laboratory chemicals and low thermal expansion, while the PTFE needle valve provides chemical resistance for compatible laboratory applications. Available in 14/23, 19/26 and 24/29 socket sizes, the range accommodates different ground glass connections commonly used in laboratory equipment.
The adapter is suitable for controlled gas transfer, laboratory liquid handling, chemical synthesis and research applications requiring an adjustable flow connection between glassware and compatible tubing. Each variation is supplied as one socket adapter with an integrated PTFE needle valve and detachable screw-thread hose connector. Safety Precautions: Inspect the glass, needle valve and connector before use. Secure compatible tubing properly, support connected apparatus and verify chemical compatibility. Avoid forcing glass joints or overtightening plastic connections. Pressure and Vacuum Information: The manufacturer does not specify maximum pressure, vacuum or leak-tightness ratings. Confirm the operating limits and sealing requirements before using the adapter in pressurised or vacuum systems.
LabChoice Australia supplies BORO 3.3 laboratory adapters, PTFE stopcocks and ground glass accessories for universities, research laboratories, chemical testing facilities and industrial laboratories across Australia.
