(Specification)Standard Specification for Blood Sedimentation Tube, Wintrobe, Glass, Reusable
Standard Specification for Blood Sedimentation Tube, Wintrobe, Glass, Reusable
ABSTRACT
This specification covers reusable blood sedimentation tubes suitable for determining sedimentation rates and the volume of packed red blood cells. The tubes shall be fabricated from borosilicate glass, Type I, Class B, or sodalime glass, Type II. A resistance to centrifugal force test shall be performed on the tubes.
SCOPE
1.1 This specification covers reusable blood sedimentation tubes suitable for determining sedimentation rates and the volume of packed red blood cells.
1.2 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.
