Swan Neck Adapters

The GISCOM Swan Neck Adapters are precision-engineered glass adapters designed to facilitate secure, multi-port connectivity within complex laboratory setups. These adapters provide three aligned necks that support simultaneous connections to condensers, thermometers, tubing, distillation systems, or reaction vessels. They ensure seamless fluid transfer, pressure equalisation, and integration across analytical, industrial, and research applications. Their robust construction and ergonomic design make them indispensable in chemical processing, organic synthesis, and controlled laboratory workflows.

Key Features

• Three parallel necks for efficient multi-point access and integration with different laboratory instruments.
• Smooth swan-neck curvature ensures unobstructed flow, minimised turbulence, and optimal direction of vapours or liquids.
• Heavy-wall Borosilicate Glass 3.3 ensures exceptional chemical, mechanical, and thermal resistance.
• Interchangeable standard taper joints for universal compatibility with laboratory glassware systems.
• Optional hose connection or screw-thread port (based on model) for thermometer insertion or tubing attachment.
• Leak-proof connections due to precision-ground joints and uniform wall thickness.
• High durability under high-temperature reactions, vacuum use, and repeated sterilisation.
• Crystal-clear transparency for easy process monitoring and visual inspection.

Material Specifications

Handling & Precautions

• Always check joint surfaces for chips or cracks before use to maintain airtight sealing.
• Compatible with autoclaving, dry heat, and standard sterilisation methods.
• Avoid direct flame exposure on one point to prevent local stress buildup.
• Clean using mild laboratory detergents; avoid abrasive pads to protect the surface finish.
• Allow gradual heating and cooling to extend glass life and reduce stress fractures.
• Ensure proper support in setups involving vacuum or pressure applications.
