Adapter Cone With Stem To Rubber Tubing

[table id=591 /]

The GISCOM Adapter Cone with Stem to Rubber Tubing is a precision-made right-angle connector designed for secure attachment between standard ground-glass joints and flexible rubber hoses. This adapter enables smooth transfer of gases or liquids between glass apparatus and external tubing, making it essential in distillation setups, vacuum systems, and fluid handling lines. Its robust construction ensures accurate, leak-free operation in demanding laboratory and industrial environments.

Key Features

• Right-angle outlet design for efficient hose connection and minimal workspace obstruction.
• Precision-ground cone joint ensures tight, leak-proof compatibility with standard glassware.
• Sturdy stem nozzle accommodates rubber tubing securely for stable fluid or gas flow.
• Made from high-quality Borosilicate Glass 3.3 for excellent chemical and thermal resistance.
• High transparency allows clear visibility of media movement.
• Smooth internal surface minimises flow resistance and contamination risks.
• Autoclavable and reusable, ensuring a long operational life.
• Engineered for vacuum and low-pressure applications with reliable performance.

Material Specifications

• Material: Borosilicate Glass 3.3

• Tolerance: Manufactured to precise dimensional accuracy and vacuum-tight standards
• Calibration: Not applicable (non-calibrated connecting adapter)
• Accessories: No additional accessories included

Handling & Precautions

• Ensure tubing fits snugly on the stem to prevent accidental detachment.
• Avoid applying excessive force while inserting or removing rubber tubing.
• Compatible with standard lab detergents; avoid abrasive cleaners.
• Autoclavable allows gradual heating and cooling to prevent thermal stress.
• Do not expose the joint or stem directly to flame.
• Inspect regularly for cracks or chips, especially around the ground joint.
• Store vertically or cushioned to avoid accidental breakage.

Applications

The adapter is widely used across scientific and industrial environments:

• Chemical and analytical laboratories
• Pharmaceutical and biotechnology R&D
• QC/QA testing labs
• Academic and research institutions
• Distillation, gas transfer, vacuum lines, and fluid-handling systems
• Connecting reaction vessels, condensers, or receivers to external tubing
  Its reliability and secure connectivity make it essential for daily workflow across multiple disciplines.
