Chemglass Evaporating Flask 100 ml 19/22 Upper Joint

The Chemglass CG-1512-58 is a heavy-wall, pear-shaped evaporating flask designed for use with rotary evaporators. Its 100 mL capacity and specific geometry make it ideal for the recovery of small to mid-sized solvent volumes while ensuring maximum sample retrieval.

Key Features and Design

• Heavy-Wall Construction: Manufactured from Type I Class A Borosilicate Glass, this flask is built for safety under high-vacuum conditions and elevated temperatures common in rotary evaporation.

• Pear-Shaped Geometry: The "recovery" shape facilitates the easy removal of solids or viscous liquids with a spatula and provides a balanced rotation on the evaporator to prevent motor wear.

• Standard Taper Joint: Features a precision-ground 19/22 outer joint for a secure, vacuum-tight connection to the vapor tube of your rotary evaporator.
