ASTM E961

ASTM E961 is the standard specification for a Blood Sedimentation Tube, Wintrobe, Glass, Reusable. It defines a technical reference for a reusable glass tube used in sedimentation testing, helping buyers and users identify a product that aligns with a recognized ASTM standard. For laboratories and procurement teams, this matters because consistent tube design and material expectations can support repeatable handling, quality control, and more dependable product selection.

Overview of ASTM E961

The official title shows that this ASTM standard addresses the specification for a Wintrobe-style blood sedimentation tube made of glass and intended for reusable use. In practical terms, ASTM E961 provides a common technical basis for describing the tube as a standardized laboratory item rather than an informal product description. This helps align purchasing, inspection, and product comparison around the same reference point, which is especially useful when uniformity and specification-based selection are important.

Common use cases of ASTM E961

ASTM E961 is commonly used when selecting or evaluating reusable glass blood sedimentation tubes for laboratory workflows. It is relevant to purchasing departments, laboratory supply catalogs, and quality-control checks where the product must be identified by a recognized standard designation. The standard may also support communication between suppliers and users when specifying a Wintrobe tube for routine handling, product comparison, or equipment-compatible laboratory use.

Benefits of using ASTM E961

Using ASTM E961 helps reduce ambiguity in procurement and product evaluation by tying the item to a clear ASTM specification. That can improve consistency across orders, support internal quality assurance, and make it easier to compare products from different sources. For organizations that rely on standardized laboratory supplies, the designation can also assist with compliance-oriented buying and reduce the risk of selecting a tube that does not match the intended reusable glass Wintrobe format.
