Full title and description

St ISO 24450-2005 — Laboratory glassware — Wide‑necked boiling flasks. This International Standard specifies requirements and dimensional series for conical flasks and for flat‑bottom and round‑bottom flasks with wide neck intended for general laboratory use; it describes sizes, neck diameters, tolerances and intended interoperability with other laboratory equipment.

Abstract

ISO 24450:2005 defines an internationally acceptable series of wide‑necked boiling flasks (conical—Erlenmeyer style—and round/flat‑bottom flasks) for general laboratory purposes, giving dimensional specifications, marking and basic requirements so that products from different manufacturers fit and interoperate in laboratory settings. For narrow‑necked boiling flasks, ISO 1773 applies; for boiling flasks with conical ground joints, ISO 4797 is referenced.

Scope

ISO 24450:2005 applies to wide‑necked boiling flasks intended for general laboratory use. It specifies dimensional series (nominal volumes and corresponding neck diameters), tolerances, marking and identification necessary to ensure interchangeability and correct use in laboratory processes. The standard does not cover narrow‑necked boiling flasks (see ISO 1773) or boiling flasks with conical ground joints (see ISO 4797).

Key topics and requirements

• Dimensional series: nominal volumes and standard neck diameters for wide‑necked conical, flat‑bottom and round‑bottom flasks.
• Tolerances on key dimensions to ensure interchangeability and fit with ancillary equipment.
• Marking and identification requirements (volume marking, manufacturer identification, nominal capacity labeling).
• Material and construction considerations appropriate for laboratory glassware (borosilicate glass commonly used; compatibility with heating and laboratory procedures implied by intended use).
• Normative references to related ISO standards (e.g., ISO 1773 and ISO 4797) for other flask types and jointed glassware.

Typical use and users

Manufacturers of laboratory glassware, procurement/specification engineers, quality control and conformity assessment bodies, laboratory managers and researchers who require standardized boiling flasks for heating, mixing and general laboratory processes. Also used by national standards bodies when producing regional/adopted versions. Typical applications include chemical and biological laboratories, educational labs and industrial R&D where standardized glassware dimensions and marking are required.

Related standards

Directly related: ISO 1773 (narrow‑necked boiling flasks) and ISO 4797 (boiling flasks with conical ground joints). National and regional adoptions exist as EN/ISO and national publications (for example EN ISO 24450 and various national transpositions). Further related documents cover laboratory equipment safety (for example requirements in IEC/EN standards for laboratory heating devices).

FAQ

Q: What is this standard?

A: ISO 24450:2005 is an International Standard that specifies dimensions and basic requirements for a series of wide‑necked boiling flasks used in laboratories (conical, flat‑bottom and round‑bottom types).

Q: What does it cover?

A: It covers the dimensional series (nominal capacities and neck diameters), tolerances and marking/identification necessary to ensure compatibility and interchangeability of wide‑necked boiling flasks for general laboratory use. It does not cover narrow‑necked flasks or flasks with conical ground joints, which are covered by other ISO standards.

Q: Who typically uses it?

A: Glassware manufacturers, laboratory procurement and QA teams, standards bodies producing national adoptions, and laboratory personnel who require standardized, interchangeable boiling flasks.

Q: Is it current or superseded?

A: The ISO bibliographic record shows ISO 24450:2005 as the Edition 1 (2005) document and indicates it was reviewed and confirmed in a subsequent ISO review cycle; it is listed as remaining current following that review. Users should check with ISO or their national standards body for any newer revisions or withdrawals.

Q: Is it part of a series?

A: It is related to other ISO standards that cover different types of boiling flasks and glass joints (notably ISO 1773 for narrow‑necked boiling flasks and ISO 4797 for boiling flasks with conical ground joints); national and EN adoptions exist that harmonize this ISO document with regional rules.

Q: What are the key keywords?

A: laboratory glassware; boiling flask; wide‑neck; Erlenmeyer; dimensions; neck diameter; ISO 24450.
