Standard Specification for
Laboratory Glass Separatory Funnels
This standard is issued under the fixed designation E 1096; 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 (e) 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.
