Description
Cone Adapter Straight with PTFE Stopcock is designed for controlled transfer and reliable shut off in laboratory distillation, reflux, vacuum, and solvent recovery assemblies. The straight bore maintains an unobstructed vapour or liquid pathway between connected components, while the integrated PTFE stopcock provides smooth, precise flow control and a dependable seal. This is particularly useful when stabilising vacuum, isolating sections of an apparatus, draining condensate, or managing controlled transfers without breaking the system and risking air ingress or solvent loss.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the adapter offers excellent thermal stability, low thermal expansion, and strong resistance to a wide range of laboratory chemicals. BORO 3.3 performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting consistent durability under heating and cooling cycles and daily laboratory handling. The PTFE plug adds broad chemical compatibility and reduces seizure risk compared with all glass taps, making it well suited to frequent operation and exposure to aggressive solvents and reagents. Precision ground joints support secure, low leak connections when properly assembled, and smooth internal surfaces help minimise hold up and support efficient cleaning.
Supplied by LabChoice Australia, this straight cone adapter with PTFE stopcock is specified across Australian university laboratories, research institutes, teaching facilities, and industrial quality control environments where dependable sealing, repeatable operation, and chemical robustness are priorities. It is a practical choice for users who need accurate control within modular glassware systems, especially under vacuum or when handling solvent rich workflows.
