1、Designation: E1096 86 (Reapproved 2018)Standard Specification forLaboratory Glass Separatory Funnels1This standard is issued under the fixed designation E1096; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi

2、on. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONSeparatory funnels are used in laboratories primarily for liquid extractions, and are intended tofacilitate the separation of two

3、 immiscible liquids of different densities into separate layers. Somefunnels are used to add reagent solution into a reaction vessel. They are, therefore, often provided witha tapered ground joint at the bottom of the delivery stem for joining to vessels having similarly taperedground necks. They ma

4、y also be provided with pressure equalizing side arms.1. Scope1.1 This specification provides standard dimensional re-quirements for glass separatory funnels for general laboratoryuse.1.2 This international standard was developed in accor-dance with internationally recognized principles on standard-
