Overview
EN ISO 24450:2005 specifies international standards for laboratory glassware, focusing on wide-necked boiling flasks, including conical, flat-bottom, and round-bottom types. Developed by ISO Technical Committee ISO/TC 48 and adopted by CEN, this standard ensures consistent dimensions, material quality, and construction requirements for these flasks, which are widely used across chemical, biological, and industrial laboratories.
The standard aims to guarantee compatibility of wide-necked boiling flasks with other laboratory equipment, promote safety, and support reproducible lab procedures globally. While EN ISO 24450:2005 covers wide-necked flasks, related ISO standards apply to narrow-necked and flasks with conical ground joints.
Key Topics
Applications
Wide-necked boiling flasks standardized by EN ISO 24450:2005 are essential in:
-
Chemical Laboratories
For mixing, heating, and boiling liquids in synthesis and analysis processes.
-
Biotechnology and Pharmaceutical Labs
Providing reliable containment during culture incubation, sterilization, and processing.
-
Industrial Quality Control
Enabling reproducible sample preparation and heating in R&D as well as production monitoring.
-
Educational and Research Institutions
Offering consistent, safe laboratory glassware suitable for teaching and experimental research.
The standard ensures that flasks interface properly with laboratory accessories such as heating mantles, clamps, and condensers, streamlining lab workflow and safety.
