Overview
SIST ISO 4798:2009 establishes the key requirements and dimensions for glass filter funnels used in laboratories. Published by SIST, this international standard applies to filter funnels intended for general laboratory purposes, specifically those that need to fit with other common laboratory glassware such as boiling flasks and volumetric flasks. The standard ensures uniformity in filter funnel design, enhancing interoperability and safety in laboratory environments.
Key Topics
- Product Scope: The standard specifies both plain and analytical glass filter funnels suitable for a broad range of laboratory applications.
- Types and Sizes:
- Plain filter funnels: Available in bowl diameters ranging from 35 mm to 200 mm.
- Analytical filter funnels: Offered in sizes of 55 mm, 75 mm, and 100 mm bowl diameters.
- Material Requirements:
- Glass used must comply with IS0 719 hydrolytic resistance class HGB3 or better for chemical durability.
- Option for borosilicate glass 3.3 as per ISO 3585, known for superior thermal and chemical resistance.
- Construction Features:
- Bowl designed as a right circular cone with a precise angle.
- Options for bowl rim: plain, beaded, or ground, with attention to filter paper alignment.
- Stems must be securely affixed, with specific requirements for taper and finish.
- Analytical funnels may have ribbing for improved filtration performance.
- Marking and Identification:
- Mandatory marking of manufacturer/supplier and glass type.
- Optional markings include bowl internal diameter and standard reference number.
Applications
Glass filter funnels covered under SIST ISO 4798:2009 are vital across various laboratory processes, including:
- Chemical Filtration: Separation of solids from liquids in chemical analysis and synthesis, using plain or analytical versions depending on the task.
- Sample Preparation: Compatible sizes and standardized designs ensure seamless integration with boiling flasks, volumetric flasks, and other laboratory glassware.
- General Laboratory Use: Used in educational, research, pharmaceutical, and industrial laboratories for routine filtrations, making processes efficient and reproducible.
- Interchangeability: Dimension and material specifications ensure that filter funnels can be easily and safely interchanged between compatible laboratory setups, reducing downtime and risk of incompatibility.
Related Standards
For seamless laboratory operations and equipment compatibility, related international standards should be referenced alongside SIST ISO 4798:2009:
- ISO 719: Hydrolytic resistance of glass - critical for assessing chemical stability.
- ISO 3585: Properties of borosilicate glass 3.3 - for material specification.
- ISO 383: Interchangeable conical ground joints for glassware.
- ISO 384: Principles of design and construction of volumetric glassware.
- ISO 641: Interchangeable spherical ground joints.
- ISO 1773: Narrow-necked boiling flasks.
- ISO 3819: Laboratory glassware - Beakers.
- ISO 4142: Test tubes and culture tubes.
- ISO 4796: Laboratory glassware - Bottles.
- ISO 4800: Separating funnels and dropping funnels.
- ISO 6556: Filter flasks.
Practical Value
Adopting the guidelines in SIST ISO 4798:2009 guarantees reliable performance and interoperability of filter funnels in laboratory environments. By following this standard, laboratories benefit from:
- Consistent Quality: Ensures all glass filter funnels meet stringent international requirements.
- Safety and Compliance: Reduces the risk of breakage or chemical incompatibilities.
- Operational Efficiency: Facilitates integration with other standardized laboratory glassware, supporting workflow efficiency.

Foreword
IS0 (the international Organization for Standardization) is a worldwide federation of national
standards bodies (IS0 member bodies). The work of preparing International Standards is
normally carried out through IS0 technical committees. Each member body interested in a
subject for which a technical committee has been established has the right to be represented on
that committee. International organizations, governmental and non-governmental, in liaison with
ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member
bodies for voting. Publication as an International Standard requires approval by at least 75 % of
the member bodies casting a vote.
