3-Way Adapters, 24/40
Manufacturer: United Scientific
The 3-Way Adapters from United Scientific are critical components for assembling complex laboratory glassware configurations, such as distillation heads or reflux setups. Manufactured from high-quality borosilicate glass, these adapters feature precision-ground 24/40 joints to ensure a leak-proof, vacuum-tight seal when used with appropriate joint grease or PTFE sleeves. Whether you are performing a standard distillation or a specialized chemical synthesis, these adapters provide the necessary geometry to connect condensers, thermometers, and boiling flasks efficiently.

Features:
- Optimized Vapor Paths: The 75° sidearm (ADTHW-24) is the industry standard for distillation heads, directing vapor toward a downward-sloping condenser
- Specialized Inclination: The 105° inclined adapter (ADB105-24) provides a sharper angle, useful for specific reflux setups or to prevent distillate hold-up in low-volume extractions
- Universal Compatibility: Standard 24/40 joints ensure these adapters fit seamlessly with your existing flasks, condensers, and thermometers
- Thermal Stability: Withstands high-temperature distillations and rapid temperature changes without cracking or losing joint integrity
Assembly & Maintenance Tips:
- Joint Integrity: Always apply a thin layer of vacuum grease (like Dow Corning High Vacuum Grease) to the ground glass surfaces before assembly to prevent "frozen" joints after heating.
- Support: Ensure the sidearm and any attached condenser are properly supported by a 3-prong clamp to prevent mechanical stress on the 24/40 joints.
- Thermometer Placement: When using the top outer joint for a thermometer adapter, ensure the thermometer bulb is positioned just below the sidearm opening for the most accurate vapor temperature reading.
