Description
The Glass Cone Adapter with Hose Connector and Drip Tip for Rubber Tubing, BORO 3.3, also known as a cone-to-hose glass adapter, laboratory rubber tubing adapter or ground glass hose connector, is designed to connect compatible laboratory glassware with flexible rubber tubing during liquid transfer and general laboratory procedures. Manufactured from borosilicate 3.3 glass, the adapter features a right-angle hose connection, integrated drip tip, screw-thread connection and a male ground glass cone. The right-angle connection allows compatible rubber tubing to be attached to the glassware assembly, providing a practical connection for laboratory liquid transfer and suitable gas-handling procedures.
An integrated glass drip tip helps direct liquid droplets towards the receiving vessel, supporting controlled drainage during appropriate collection and transfer applications. The screw-thread connection accommodates appropriately matched hose fittings. The manufacturer does not specify the thread dimensions or included securing components, so compatibility should be confirmed before selecting tubing. The male ground glass cone fits into a corresponding female ground glass socket, allowing the adapter to connect to compatible laboratory flasks and other jointed apparatus. The BORO 3.3 glass construction provides low thermal expansion and resistance to many laboratory chemicals, making the adapter suitable for compatible distillation, chemical synthesis and laboratory liquid-handling procedures.
Available in four DIN cone sizes, including 14/23, 19/26, 24/29 and 29/32, the range allows users to select a connection that matches their existing laboratory glassware. Its transparent construction also allows users to inspect the internal passage for visible residue or glass damage before installation. Each variation is supplied individually, with one glass cone adapter per pack.
Safety Precautions: Inspect the adapter for cracks or damaged joints before use. Secure compatible tubing, support the assembled apparatus with suitable clamps and verify chemical compatibility. Avoid forcing ground glass joints together. Pressure and Vacuum Information: The manufacturer does not specify maximum pressure, vacuum or leak-tightness ratings. Confirm these requirements before using the adapter in pressurised or vacuum systems.
LabChoice Australia supplies BORO 3.3 laboratory glassware, ground glass adapters and rubber tubing connection accessories for universities, research laboratories, chemical testing facilities and industrial laboratories across Australia.
