Single Neck Reaction Schlenk flask

The 2mm precision glass stopcock with spring retention is a significant quality feature - it provides smooth, controlled operation for vacuum/inert gas manipulations, which is essential for air-sensitive chemistry. The spring mechanism reduces the likelihood of the stopcock seizing or becoming difficult to turn over time.

Specifications:

• Capacity: 100 mL
• Joint size: ST/NS 14/20 (Standard Taper/Normal Schliff, 14mm inner diameter, 20mm length)
• Glass type: Heavy-duty thick-wall borosilicate glass (excellent thermal shock resistance and chemical durability)

Typical Applications:

• Air-sensitive reactions under an inert atmosphere (nitrogen or argon)
• Reactions requiring a vacuum
• Organometallic chemistry
• Catalyst preparation
• Any synthesis requiring the exclusion of oxygen/moisture

The heavy-wall construction is particularly valuable for withstanding repeated thermal cycling and vacuum applications without cracking. The 14/20 joint size is smaller and suitable for this volume range.
