Description
The Cone Joint with Drip Tip from Osmosis Scientific is an essential component for technicians and glassblowers requiring high-performance connections in laboratory apparatus. Crafted from premium Boro 3.3 borosilicate glass, these joints offer the chemical durability and thermal stability necessary for demanding distillation and reaction environments.
The defining feature of this joint is the integrated drip tip. When used in a vertical or angled setup, the tip ensures that condensed liquid drops directly into the receiving vessel or column center, preventing “side-wall creep” and minimizing sample loss or contamination. This makes them particularly effective for distillation heads and condenser outlets.
These joints are unprinted to ensure a clean, professional aesthetic and maximum visibility during reactions. Each piece is precision-ground to a standard taper, ensuring a vacuum-tight and leak-proof seal when paired with matching sockets. The adherence to DIN/ISO dimensions ensures universal compatibility with existing laboratory glassware setups worldwide.
Note: For outsourced or specialized components, Osmosis Scientific acts as a supplier and distributor. Compliance with international standards is maintained through rigorous manufacturing protocols; however, the original manufacturer holds responsibility for primary certification. Osmosis Scientific shall not be held liable for mechanical failure or breakage resulting from improper joint greasing, excessive torque, or use in pressurized environments for which the glass is not rated.

Frequently Asked Questions (FAQs)
Unprinted joints are clear and free from enameled logos or size markings. This is ideal for:
- Custom Glassblowing: Allowing for a seamless look when fused to other glass components.
- High-Purity Work: Eliminating any risk of ink leaching or interference during sensitive reactions.
The drip tip is an integral part of the joint, fire-polished to ensure a smooth, rounded edge that promotes consistent drop formation and prevents chipping.
Clean as you would standard glassware, ensuring that the narrow area of the drip tip is free from residue. They are fully autoclavable and resistant to repeated sterilization cycles.
Even with a drip tip, it is best practice to use a light coating of silicone or vacuum grease, or a PTFE sleeve, especially if the reaction involves caustic chemicals or high temperatures.
