Adapters, Socket/Cone with Stopcock, Borosilicate Glass

Glass Agencies presents the Erose Socket/Cone Adapter with Stopcock, manufactured from high-quality borosilicate glass for controlled transfer of gases or liquids within laboratory glassware systems. This adapter combines a ground-glass socket on one end and a cone joint on the other, allowing connection between compatible components while incorporating a stopcock for flow regulation. Its structure supports flexible system configuration and controlled operation.

The socket and cone joints provide stable, leak-resistant connections when paired with standard laboratory glassware. This dual-ended configuration allows the adapter to be inserted between flasks, condensers, receivers, or other accessories where flow control is required. The integrated stopcock enables gradual opening and closing, allowing users to regulate the passage of gases or liquids without disturbing the rest of the assembly.

Manufactured from borosilicate glass, the Erose socket/cone adapter withstands thermal variation encountered during laboratory heating and cooling cycles. The material resists interaction with acids, alkalis, and many solvents, maintaining clarity and structural stability. The transparent construction allows visual monitoring of internal flow and cleanliness during operation.

The stopcock features a tapered glass plug that rotates smoothly within the body. When properly lubricated with suitable stopcock grease, the glass-to-glass contact supports consistent sealing and smooth adjustment. This allows controlled flow without sudden pressure changes, supporting stable experimental conditions.

Erose Socket/Cone Adapters with Stopcock are commonly used in distillation setups, reflux assemblies, gas handling systems, vacuum lines, and filtration processes. They help manage flow direction and intensity while maintaining secure connections between glassware components. Their compact structure allows use in both vertical and horizontal orientations depending on system layout.

Glass Agencies ensures each adapter undergoes inspection for accurate joint dimensions, smooth stopcock rotation, uniform wall thickness, and clear finish. Every unit reflects consistent manufacturing standards aimed at meeting laboratory requirements. The smooth internal and external surfaces support easy cleaning and repeated use.
