Introduction

Schlenk flasks enable air-sensitive reactions under vacuum or inert gas. Select borosilicate glass with standard taper joints and side-arm stopcocks. Match flask volume to your typical reaction scale for safe handling.

  • Thick-walled glass resists thermal shock
  • Ground-glass joints for secure sealing
  • Compatible with common Schlenk lines and manifolds

Browse laboratory vacuum flasks for research use.

FAQs

25 mL to 250 mL flasks cover most small-scale organic reactions. Larger volumes require additional safety measures.

Yes, if fitted with an appropriate condenser and vacuum adapter. Confirm joint sizes match before setup.

Rinse with appropriate solvent, then soak in a mild base or acid bath. Avoid abrasive brushes that scratch the glass.

Many modern stopcocks use PTFE cores that require no grease, reducing contamination risk.

Wear safety goggles, gloves, and a lab coat. Work inside a fume hood when handling air-sensitive reagents.
