Cone Full Length Plain End Single

Cone Full Length Plain End Single Adapters, also widely classified as single male ground joints with straight unsealed tubes, are structural component building blocks utilized in custom laboratory glassblowing and modular apparatus configuration. Fabricated from premium-grade borosilicate glass, this component features a standard full-length precision-ground male cone joint on one end, terminating into a straight, clear, unformed plain glass tube on the other.

The "Full Length" specification ensures strict compliance with standard international ground taper dimensions (such as the ASTM or long-taper ISO profiles), providing maximum contact surface area for structural stability and a rigorous, vacuum-tight seal. The plain unsealed end allows glassblowing workshops to easily fuse this component onto customized reaction flasks, specialized gas delivery manifolds, distillation columns, or custom extraction systems.

Key Features

• Manufactured from high-purity borosilicate 3.3 glass for maximum chemical resistance, optical clarity, and thermal durability
  
• Full-length ground male cone taper engineered to provide maximum surface contact for superior vacuum integrity
  
• Straight plain unformed tube end optimized for easy fusion, cutting, or modification by laboratory glassblowers
  
• Heavy-wall glass construction ensuring uniform thermal expansion coefficients during glassblowing manipulation
  
• Chemically inert glass surface prevents cross-contamination, ensuring absolute sample purity in final assemblies
• International Standards

Our full-length single cone components are engineered and manufactured in strict compliance with globally accepted dimensional and joint taper metrics, ensuring perfect alignment across international brands:

• ISO 383 – Laboratory Glassware – Interchangeable Conical Ground Joints
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing
  
• ASTM E676 – Standard Specification for Ground Joints Interchangeable Taper-Ground
• Available in a full range of standard long-taper joint sizes (e.g., 14/23, 19/26, 24/29, 29/32, 34/35, 45/40). The length and diameter of the plain glass tube extension can be custom tailored or extended to match specific commercial manufacturing blueprints or large bulk contract requirements.

Applications

Primary component resource for scientific glassblowing shops, laboratory apparatus manufacturing factories, industrial R&D departments building custom multi-neck glass reactors, high-vacuum manifold assemblies, and academic chemistry maintenance workshops.
