10 ml to 1000 ml | Short Neck | Ground Joint

4

The CS-F90 Schlenk Flask is a high-quality laboratory reaction vessel designed for air- and moisture-sensitive chemistry. Manufactured from durable borosilicate glass, this pear-shaped flask features an integrated glass stopcock and standard ground-glass joint, allowing controlled evacuation, inert gas purging, and reagent transfer under vacuum or protective atmosphere.

Ideal for organometallic synthesis, catalysis, and advanced chemical research, this Schlenk flask supports routine Schlenk-line operations while offering excellent thermal and chemical resistance.

Key Features

• Borosilicate Glass Construction
  High resistance to thermal shock, acids, and most laboratory solvents.

• Integrated Glass Stopcock
  Enables precise control of vacuum and inert gas flow without external valves.

• Pear-Shaped Body
  Promotes efficient mixing and heat transfer during reactions.

• Standard Ground Joints
  Available in 14/20, 19/22, and 24/40 for compatibility with common lab setups.

• Short Neck Design
  Compact profile suitable for fume cupboards and Schlenk lines.

• Transparent Finish
  Clear visibility of reaction progress and contents.
