Standard Specification for Laboratory Glass Microvolumetric Vessels (Volumetric Flasks and Centrifuge Tubes)

ABSTRACT
This specification covers microvolumetric glass vessels (volumetric flasks and centrifuge tubes) widely used in microchemistry. The volumetric flasks shall conform to the design and dimensional requirements specified for the two styles illustrated herein. The centrifuge tubes shall be either of the four types, as follows: plain with a conical bottom; stoppered with a conical bottom; stoppered and graduated with a conical bottom; and plain with a cylindrical bottom. The centrifuge tubes shall also conform to the design and dimensional requirements specified for the four types illustrated herein.
SCOPE
1.1 This specification covers volumetric flasks and four types of centrifuge tubes, widely used in microchemistry. Note 1Specifications for several items listed below were developed by the Committee on Microchemical Apparatus, Division of Analytical Chemistry, American Chemical Society.
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 .

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
