Description
The Cone Adapter with Long Stem and Hose Connection, BORO 3.3 Glass, also known as a long stem glass adapter, cone-to-hose adapter or laboratory ground glass tubing connector, is designed to connect compatible laboratory glassware with rubber tubing during gas transfer, liquid handling and chemical laboratory procedures. Manufactured from borosilicate 3.3 glass, the adapter features an extended glass stem, a right-angle tubing connection, a detachable plastic screw-thread fitting and one male ground glass cone. The long stem design provides an extended connection between the ground glass joint and hose attachment, supporting convenient integration into laboratory apparatus where additional stem length is beneficial.
The right-angle hose connection allows compatible rubber tubing to be attached using the detachable plastic screw-thread fitting. This arrangement facilitates hose attachment and removal during laboratory setup and maintenance. The male ground glass cone fits into a matching female socket on laboratory flasks or other jointed apparatus, providing a standard taper connection for compatible glassware assemblies. The BORO 3.3 glass construction offers low thermal expansion and resistance to many laboratory chemicals. Its transparent design also allows visual inspection of the glass passage before use. Available in 14/23, 19/26, 24/29 and 29/32 cone sizes, the adapter accommodates different laboratory glassware configurations. Users should select the joint size and compatible hose according to their apparatus requirements.
The adapter is suitable for laboratory gas transfer, compatible liquid-handling arrangements, chemical synthesis and research applications, subject to the operating conditions and material compatibility of the complete assembly. Each variation is supplied individually, with one long stem glass cone adapter and detachable screw-thread hose fitting per pack. Safety Precautions: Inspect the glass, threaded fitting and hose connection before use. Secure tubing properly, support assembled glassware and avoid forcing incompatible ground joints together. Pressure and Vacuum Information: The manufacturer does not specify a pressure rating, vacuum rating or verified leak-tightness performance. Confirm these requirements before incorporating the adapter into pressurised or vacuum systems.
LabChoice Australia supplies BORO 3.3 glass adapters, ground glass joints and laboratory tubing connection accessories for universities, research laboratories, chemical testing facilities and industrial laboratories across Australia.
