Swan Neck Adapters (thermometer Adapter)

Swan Neck Adapters (Thermometer Adapters) are highly specialized laboratory glassware components designed to safely introduce thermometers, temperature probes, or gas inlet tubes into distillation and reaction setups. Fabricated from premium borosilicate glass, these adapters feature a classic curved, dual-neck geometry that offsets the thermometer placement from the main vapor column or stirring axis.

The intelligent "swan neck" curves provide parallel vertical paths or specialized angled alignments. This ensures that a thermometer bulb can be placed perfectly at the vapor distillation intersection without physically obstructing mechanical overhead stirrers or reactant addition lines. Equipped with precision interchangeable ground glass joints, these adapters maintain a completely gas-tight, vacuum-capable seal across complex chemical assemblies.

Key Features

• Manufactured from high-purity borosilicate 3.3 glass for maximum chemical resistance and superior thermal shock durability
  
• Unique swan-neck curved profile designed to eliminate spatial conflicts between stirrers and temperature sensors
  
• Precision-ground interchangeable upper outer sockets (female) and lower inner cones (male) for leak-proof performance
  
• Heavy-wall glass tooling at critical curved stress points to maximize mechanical strength and structural longevity
  
• Smooth, non-porous internal glass pathways to prevent vapor restriction or solute accumulation
• International Standards

Our specialized thermometer adapters are engineered and manufactured in strict compliance with globally accepted dimensional and quality parameters, ensuring seamless compatibility across international markets:

• ISO 4797 – Laboratory Glassware – Flasks with Ground Joints and Connection Heads
  
• ISO 383 – Laboratory Glassware – Interchangeable Conical Ground Joints
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing
• Available in multiple interchangeable joint size combinations (such as 14/23, 19/26, 24/29, 29/32) across the vertical socket, secondary socket, and lower cone. Custom offset distances, specialized screw-thread caps (GL-threads) with silicone/PTFE rings for direct thermometer clamping, or customized tube diameters can be manufactured per bulk specification.

Applications

Extensively utilized in fractional distillation lattices, multi-neck reactor vessel monitoring, vacuum distillation of temperature-sensitive compounds, pharmaceutical synthesis monitoring, and academic organic chemistry research.
