Borosilicate Glass Delivery Tubes Set Of 6

The Borosilicate Glass Delivery Tubes Set is a versatile collection of high-purity laboratory glassware components engineered for the safe routing, transfer, and collection of gases and vapors during chemical reactions. Fabricated from premium borosilicate 3.3 glass, these tubes provide exceptional thermal durability, making them highly resistant to structural cracking when subjected to direct heating or rapid temperature changes across laboratory setups.

This commercial-grade set includes six distinct, precision-bent tube geometries tailored to fit standard experimental arrangements—such as gas generation flasks, distillation configurations, and pneumatic troughs. Each tube is designed with smooth, fire-polished ends to ensure structural integrity, prevent chipping, and allow for easy, airtight insertion into rubber stoppers or silicone tubing without tearing the seals.

Set Configurations & Profiles

Each standard set of 6 contains an optimized selection of angles and shapes to fulfill diverse laboratory requirements:

• Straight Delivery Tube: Ideal for direct horizontal or vertical gas extensions
  
• 90-Degree L-Shape Tube: Standard bend for routing gas from vertical flasks to horizontal condensing paths
  
• 60-Degree Angled Tube: Optimized for sloping distillation configurations and collection systems
  
• U-Shape Tube: Perfect for bridging parallel gas washing bottles or building fermentation traps
  
• S-Shape / Offset Tube: Designed to bypass structural framework obstructions within tight lattice arrangements
  
• Swan-Neck / Double-Bent Tube: Engineered for advanced pneumatic trough gas collection under water matrices
• Key Features

• Manufactured from premium borosilicate 3.3 glass for maximum chemical resistance and a low coefficient of thermal expansion
  
• Fire-polished tips provide smooth, rounded edges that improve safety and protect rubber or silicone fittings
  
• Uniform internal bore diameter and consistent wall thickness ensure stable gas flow dynamics and high mechanical strength
  
• Chemically inert glass construction prevents contamination, ensuring high-purity gas transfer across analytical runs
  
• Highly durable design stands up to repeated autoclaving, acid washing, and hot air sterilization cycles
• International Standards

Our glass delivery tubes are engineered and manufactured in strict compliance with globally accepted scientific dimensional parameters, ensuring seamless integration into international educational and B2B tender specifications:

• ISO 4788 / DIN Standards – Metric Dimensions for Laboratory Glass Tubing and Apparatus Components
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing (Type I, Class A)
  
• CE / Educational Supply Quality Alignment – Approved for institutional science procurement and bulk contract bidding
• Standard outer diameter options include 6mm, 7mm, or 8mm to match standard laboratory rubber bung perforations. Custom assortments, specific limb lengths, or individual protective compartment boxing can be provided to fulfill large-scale institutional tenders or custom wholesale requirements.

Applications

Extensively utilized across secondary school science laboratories, university chemistry departments, environmental testing centers, gas generation demonstrations (e.g., $CO_2$ or $H_2$ tracking), and organic synthesis research assemblies.
