ASTM E1045-00(2022) PDF

Overview

ASTM E1045-00(2022): Standard Specification for Pipet, Sahli Hemoglobin establishes requirements for reusable Sahli hemoglobin pipets. These laboratory pipets are crucial for hemoglobin determinations, especially in clinical and research settings involving blood analysis. The standard outlines material specifications, construction features, dimensional tolerances, required markings, and testing methods to ensure reliable and accurate measurements. Developed in line with internationally recognized principles, this standard supports quality, repeatability, and traceability in medical laboratory practices worldwide. All values within this standard are stated exclusively in SI units, underpinning consistency in global laboratory operations.

Key Topics

• Material and Construction

  • Pipets must be crafted from spirit bore white back tubing or clear glass with a white stripe.
  • The design is straight and constructed from a single piece, enhancing durability and ease of cleaning.
  • Cross sections must be circular, supporting accurate volumetric delivery.

• Design and Dimensions

  • Delivery tips must feature a gradual or concave taper, with tips ground or fire-polished for uniform sample delivery.
  • Tolerances for length and dimensions are specified, ensuring pipets are fit for Hemoglobin measurement procedures.

• Calibration and Marking

  • Each pipet is calibrated to contain 20 cubic millimeters (cmm) of whole blood.
  • Graduation lines, volumetric designation, manufacturer identification, and capacity deviation are permanently marked, typically in black or amber, ensuring easy visual verification and traceability.

• Testing Requirements

  • Pipets undergo rigorous performance evaluations, including:
    • Capacity tests (using distilled water and precision weighing equipment)
    • Capacity deviation measurement
    • Pigmentation test to ensure marks do not discolor from cleaning
    • Strain-free verification using polariscope analysis

Applications

Reusable Sahli hemoglobin pipets specified by ASTM E1045-00(2022) are utilized primarily in:

• Clinical laboratories conducting blood hemoglobin determinations for patient diagnostics.
• Research institutions studying hematological disorders or developing new analytical techniques for blood assays.
• Medical device manufacturers producing laboratory apparatus according to recognized quality standards.
• Quality control settings where traceability, measurement accuracy, and repeatability are critical.

The robust testing and marking requirements defined in ASTM E1045-00(2022) ensure that pipets deployed in blood analysis deliver confidence in measurement results and uphold laboratory best practices.
