ASTM E1096-86(2024)

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation: E1096 − 86 (Reapproved 2024)
Standard Specification for
Laboratory Glass Separatory Funnels
This standard is issued under the fixed designation E1096; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Separatory funnels are used in laboratories primarily for liquid extractions, and are intended to
facilitate the separation of two immiscible liquids of different densities into separate layers. Some
funnels are used to add reagent solution into a reaction vessel. They are, therefore, often provided with
a tapered ground joint at the bottom of the delivery stem for joining to vessels having similarly tapered
ground necks. They may also be provided with pressure equalizing side arms.
