Bent 105° Vacuum Adapter, 24/40 Joint
Manufacturer: United Scientific
The Bent 105° Vacuum Adapter from United Scientific is a specialized component designed for precision distillation setups. Crafted from high-quality borosilicate glass, this adapter features standard taper 24/40 joints that provide a secure, vacuum-tight fit with matching laboratory glassware. The unique 105° angle is specifically engineered to facilitate efficient vapor flow while the integrated drip tip ensures that distillate is directed cleanly into the receiving flask, preventing backflow into the joint area. The side-mounted hose connector allows for easy attachment to a vacuum source, essential for reduced-pressure distillations.
Description
Standardized for compatibility with most organic chemistry glassware kits.
Features:
- Precise Distillate Delivery: The delivery tube extends significantly below the lower inner joint, ensuring that your collected product enters the receiving flask without coming into contact with joint grease
- Vacuum Compatibility: The heavy-walled glass construction and precision-ground joints are designed to hold a stable vacuum, reducing the boiling point of heat-sensitive compounds
- Thermal Shock Resistance: Manufactured from low-expansion borosilicate glass, this adapter can withstand the rapid temperature gradients common in distillation workflows
- Universal Fitting: The 24/40 joint size is the industry standard, allowing this adapter to be used with a wide variety of condensers, flasks, and cow-type receivers
Assembly & Safety Tips:
- IMPORTANT! Joint Maintenance: Always apply a very thin uniform layer of high-vacuum grease to the ground glass joints to ensure a hermetic seal and prevent the joints from "freezing" or seizing after heating
- Vacuum Tubing: Use heavy-walled vacuum tubing when connecting to the hose barb to prevent the tubing from collapsing under pressure
- Support: Ensure the adapter is properly supported by a 3-prong extension clamp to avoid putting mechanical stress on the glass joints during assembly
