That item is a 75° Distillation Adapter (often called a Still Head or Connecting Adapter). It is the "bridge" in a standard distillation setup, positioned between the vertical boiling flask and the sloped condenser.
Key Technical Specifications
- Angle: 75-degree bend, which provides the optimal slope for vapor to travel from the flask into the condenser.
-
Joints:
- Bottom (Cone): Connects to the boiling flask (e.g., 24/29 or 19/26).
- Side (Cone): Connects to the condenser.
- Material: High-expansion 3.3 Borosilicate Glass for high-heat resistance.
Core Functions
- Vapor Path: It directs rising hot vapors toward the cooling zone of the condenser.
- Seal Integrity: Precision ground joints ensure a leak-proof system, preventing loss of product or exposure to fumes.
Pro-Tips for Use
- Joint Grease: Always apply a thin layer of vacuum grease to the joints before assembly to prevent "freezing" (stuck joints) after heating.
- Clamping: Always clamp the adapter itself or the flask immediately below it to ensure the weight of the condenser doesn't tip the setup.
