Description
The T-Shaped Glass Adapter with Cone Joint and PTFE Needle Valve Stopcock, BORO 3.3, also known as a laboratory T-shaped stopcock adapter, glass needle valve adapter or ground glass cone connector, is designed for connecting laboratory glassware to compatible rubber tubing while providing precise manual flow control. Manufactured from borosilicate 3.3 glass, the adapter combines a T-shaped body, male ground glass cone, adjustable PTFE needle valve and detachable plastic screw-thread hose connector. The PTFE needle valve stopcock provides fine adjustment and positive closure for controlling compatible gas or liquid flow. Its manufacturer-listed 0–3.0 mm bore range allows manual regulation of the flow passage during laboratory procedures.
The detachable plastic screw-thread connection accommodates appropriately sized rubber tubing, allowing the adapter to be incorporated into compatible gas-handling and liquid-transfer assemblies. The male ground glass cone fits into a corresponding female socket on laboratory flasks or other glassware. The available 14/23, 19/26 and 24/29 joint sizes provide options for different apparatus configurations. The BORO 3.3 glass construction offers chemical resistance and low thermal expansion, while the PTFE valve provides resistance to many laboratory chemicals. Compatibility must be checked against the complete assembly, including the plastic hose connector. The T-shaped configuration is suitable for laboratory gas transfer, controlled reagent flow, chemical synthesis and research experiments requiring an adjustable connection between glassware and flexible tubing.
Each variation is supplied individually, with one T-shaped adapter and integrated PTFE needle valve stopcock per pack. Safety Precautions: Inspect the glass, valve and threaded connector before use. Secure all tubing connections, support the apparatus with appropriate clamps and avoid forcing ground glass joints together. Pressure and Vacuum Information: Maximum pressure, vacuum and leak-tightness ratings are not specified. Verify these requirements before incorporating the adapter into pressurised or vacuum systems.
LabChoice Australia supplies BORO 3.3 glass adapters, PTFE stopcocks and laboratory glassware accessories for universities, research laboratories, chemical testing facilities and industrial laboratories across Australia.
