The MEDILAB Adapter, Drying Tube, is a specialised glass connector designed to protect moisture-sensitive reactions by preventing atmospheric humidity from entering a reaction vessel. It features a ground joint on one end for secure attachment to flasks or reaction setups, while the elongated tube allows filling with drying agents such as calcium chloride or silica gel. Essential for synthetic chemistry, analytical experiments, and controlled-environment reactions, this adapter ensures clean, dry conditions for accurate and reproducible results.
Key Features
- Precision-ground joint for airtight, leak-free attachment to reaction vessels.
- The extended tube design accommodates a wide range of drying agents.
- Made from premium Borosilicate Glass 3.3, ensuring exceptional thermal and chemical resistance.
- Smooth, transparent surface for clear visibility of drying media.
- Resistant to moisture, corrosion, and aggressive chemicals used in laboratory environments.
- Suitable for both vertical and angled configurations, depending on apparatus setup.
- An optional straight drying tube adapter is available upon request.
