Standard Specification for Laboratory Glass Separatory Funnels

ABSTRACT
This specification provides standard dimensional requirements for glass separatory funnels for general laboratory use. Separatory funnels shall be in the following types: Type 1A; Type 1B; Type 1C; Type 2; Type 3; and Type 4. Separatory funnels shall be made of borosilicate glass conforming to the requirement specified. The design of each separatory funnels shall comply with the dimensions given in each requirements.
SCOPE
1.1 This specification provides standard dimensional requirements for glass separatory funnels for general laboratory use.  
1.2 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.

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.
