Designation: E1047 − 85 (Reapproved 2010) E1047 − 85 (Reapproved 2015)
Standard Specification for
Blood Sedimentation Tube, Wintrobe, Glass, Disposable
This standard is issued under the fixed designation E1047; 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.
1. Scope
1.1 This specification covers disposable blood sedimentation tubes suitable for determining sedimentation rates and the volume
of packed red blood cells.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The following precautionary statement pertains only to the test method portion, Section 7 of this specification.This standard
does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this
standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 disposable, n—in accordance with this specification and the expected product performance expressed in this standard,
those tubes which are to be used one time only. Any institution or individual who reuses a disposable tube must bear full
responsibility for its safety and effectiveness.
3.1.2 Wintrobe , n—surname of the individual responsible for the design of the reusable Wintrobe tube and the method of use
for both reusable and disposable tubes.
4. Classification
4.1 This specification covers a tube that is intended to be used one time only. It is not to be confused with a reusable tube that
is described in other published standards.
5. Materials
5.1 Glass—The tubes made to this specification shall be fabricated borosilicate glass, Type I, Class B, or from soda lime glass,
Type II, in accordance with Specification E438.
6. Physical Requirements
6.1 Design—The tube shall be made of tubing with a minimum wall thickness of 0.6 mm. The tube shall have a cylindrical body
terminating in a round bottom on the outside and a flat bottom on the inside. The tube shall have a uniform bore and a fire-polished
top.
6.2 Workmanship—The tube shall be free as possible from visible defects which detract from its serviceability. The tube shall
be well annealed so there will be no ring strain evident when tested under a polariscope.
This specification is under the jurisdiction of ASTM Committee E41 on Laboratory Apparatus and is the direct responsibility of Subcommittee E41.01 on Laboratory
Ware and Supplies.
