Chemglass Erlenmeyer Flask 14/20 STJ 25 ml Capacity Lot of 5 Flasks

The Chemglass CG-1542-42 Erlenmeyer Flask is a specialized laboratory flask designed for applications requiring a secure, vacuum-tight connection. This model is a staple for microscale and small-scale chemistry, featuring a 25 ml capacity and a 14/20 outer (female) standard taper joint. Some of the most common applications include microscale organic synthesis, sample storage, and analytical titrations.

Core Performance Features

• Precision Ground Joint: The 14/20 outer joint provides a precision-ground surface that ensures an airtight and vacuum-tight seal when paired with standard 14/20 inner (male) joints.

• Durable Borosilicate Glass: Manufactured from high-quality, low-expansion borosilicate glass, it offers excellent resistance to chemical corrosion and thermal shock, making it safe for heating on hotplates or sand baths.

• Erlenmeyer Geometry: Its classic conical shape provides a broad base for stability and is optimized for swirling and mixing liquids without the risk of splashing or spillage.

• Small-Scale Optimization: The 25 ml volume is ideal for microscale synthesis, minimizing waste and reagent consumption in analytical or research environments.

Used, in great condition.
