Erlenmeyer Flask with Screw Cap – Secure Closure for Laboratory and Research

Erlenmeyer flasks with screw caps combine the classic conical shape of the Erlenmeyer flask with a practical ISO-standard screw thread. The integrated screw cap enables a tight, removable closure and is ideal for storage, transport, as well as shaking and incubation procedures.

Technical Features:

• Material: Borosilicate glass 3.3 according to DIN ISO 3585
• Screw thread: GL 25, GL 32, or GL 45 (depending on volume)
• Screw cap with seal included in delivery
• Autoclavable at 121 °C
• Conical flask shape for optimal mixing and aeration
• High chemical and thermal resistance
• Graduation for volume orientation

Important Handling Note:

During autoclaving, the screw cap must only be placed loosely on top and must not be fully tightened to allow pressure equalization and prevent glass breakage.

Application Areas:

• Cell culture and microbiology
• Fermentation and incubation
• Shaking cultures
• Sample storage and transport
• Analytical preparation
• General laboratory work

The Erlenmeyer flasks with screw caps are available in various nominal volumes from 50 ml to 5000 ml and cover a wide range of standard laboratory applications.
