Claisen Heads (sloping With 2xb-14 Socket)

Claisen Heads (Sloping with 2x B-14 Sockets) are premium laboratory glassware adapters designed to expand the utility of distillation assemblies. Fabricated from high-purity borosilicate glass, these specialized heads feature a secondary vertical neck alongside the primary vapor path, allowing for the simultaneous insertion of multiple components—such as thermometers, capillary tubes, or dropping funnels—without obstructing the main distillation run.

This specific configuration is engineered with dual interchangeable B-14 outer sockets (female joints) at the top, paired with a downward-sloping side arm that ensures smooth vapor transition toward a condenser setup. The strategic Claisen architecture provides an effective defense against "bumping" or vigorous boiling by forcing the vapor through a secondary offset path, preventing unvaporized liquid droplets from contaminating the pure distillate.

Key Features

• Manufactured from premium borosilicate 3.3 glass for superior chemical inertness and maximum thermal shock resistance
  
• Features two parallel or offset B-14 top sockets to easily accommodate standard thermometers, stirrers, or addition funnels
  
• Downward-sloping side arm optimized to promote efficient vapor flow and eliminate distillate holdup
  
• Meticulously ground interchangeable conical joints to ensure a completely airtight, vacuum-compliant seal
  
• Heavy-wall glass construction reinforced at critical intersections for enhanced mechanical strength and durability
• International Standards
• Our Claisen distillation heads are engineered and manufactured in strict compliance with globally accepted dimensional and quality parameters, ensuring seamless integration into international export setups:

• ISO 4797 – Laboratory Glassware – Flasks with Ground Joints and Connection Heads
  
• ISO 383 – Laboratory Glassware – Interchangeable Conical Ground Joints (B-Style Tapers)
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing
• Standard bottom cone and sloping side cone joint sizes can be tailored (e.g., B-14, B-19, or B-24) to interface perfectly with your primary boiling flasks and condensers. Custom angles, specialized jacketed designs, or alternative socket dimensions can be engineered based on bulk commercial parameters.

Applications

Extensively utilized in fractional distillation, vacuum distillation of air-sensitive compounds, organic synthesis setups requiring continuous monitoring, pharmaceutical testing, and academic research configurations where precise multi-port control is critical.
