    Abstract

    This specification covers volumetric pipets of two classes. Class A, Precision Pipet and Class B, General Purpose. Borosilicate glass for pipets shall conform to the glass requirements specified. Pipets shall be calibrated to deliver the intended capacity. The pipets shall consist in general of a suction tube and a delivery tube separated by a bulb; all three parts shall be permanently attached together. All markings shall be permanent and legible.

    1. Scope

    1.1 This specification covers volumetric pipets of two classes. Class A, Precision Pipet and Class B, General Purpose.

    Note 1Specifications for micropipets are given in Specification E193.

    1.2 Product with a stated capacity not listed in this standard may be specified class A tolerance when product conforms to the tolerance range of the next smaller volumetric standard product listed in Table 1.
