Flow Control Bend Adapter with PTFE Stopcock BORO 3.3 Glass Laboratory Grade
didn't see what you are looking for ?
Flow adapters with bend geometry and integrated stopcocks supplied by LabChoice Australia are engineered to provide controlled direction of vapours, gases or liquids within jointed glassware assemblies used for distillation, reflux, inert gas work and general synthetic chemistry. Manufactured from high quality BORO 3.3 borosilicate glass compliant with ISO 3585 and ASTM E438 Type 1 Class A standards, these adapters offer excellent thermal resistance, chemical durability and dimensional precision. Their strong structural stability supports reliable performance during repeated heating and cooling cycles, making them suitable for advanced laboratory processes.
The angled bend design provides efficient redirection of flow paths, allowing technicians to configure distillation lines, vacuum systems or gas introduction points with improved spatial arrangement. The integrated stopcock, available in glass or PTFE depending on the model, enables precise flow regulation and complete shut off when required. This allows safe control of vapour transfer, gas purging, solvent routing and reduced pressure operations. The precision ground joints ensure airtight sealing with standard cone and socket glassware, preventing vapour leakage and supporting consistent internal pressure during sensitive procedures.
These adapters are commonly used in organic synthesis, essential oil distillation, chromatography preparation, inert atmosphere reactions, vacuum manifold setups and educational laboratories. Their ability to combine directional flow management with fine valve control makes them ideal for handling reactive gases, volatile solvents and delicate distillation products. The clarity of BORO 3.3 glass provides full visibility of vapour movement, condensate formation and stopcock performance throughout the process.
Every flow adapter bend adapter with stopcock supplied by LabChoice Australia undergoes ISO 9001 aligned quality control procedures. This includes dimensional verification of all joints, valve operation testing, clarity and surface finish inspection, wall thickness measurement and assessment of structural integrity. Stopcocks are tested for smooth movement, consistent sealing and chemical compatibility. These stringent checks ensure that each adapter delivers reliable, leak free and precise performance in demanding laboratory environments.
