ASTM E1045-00(2016)

Standard Specification for Pipet, Sahli Hemoglobin

ABSTRACT
This specification covers reusable Sahli hemoglobin pipets. The pipets shall be made of common spirit bore white back tubing. Pipet design shall be straight and of one-piece construction. Pipet delivery tips shall be made with a gradual or concave taper. Pipet dimensions shall be within tolerance limit indicated in this specification. The pipet shall have markings which include graduation line, volumetric designation, identification, and capacity deviation. Testing methods include capacity test, capacity deviation, pigmentation test, and strain free test.
SCOPE
1.1 This specification covers reusable pipets calibrated “to contain” 20 cmm of whole blood and used for hemoglobin determinations.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.

3. Materials
3.1 The pipets shall be made of common spirit bore white back tubing or of clear glass with a white stripe applied to the outer
surface of the tubing.
4. Design
4.1 Shape—Pipets shall be straight and of one-piece construction. Any cross section of a pipet taken in a plane perpendicular
to the longitudinal axis should be circular.
4.2 Delivery Tips—Delivery tips shall be made with a gradual or concave taper to a length of 10 to 25 mm. The tip end shall
be ground and tapered with fine abrasive, or fire-polished. Dimensions of the delivery tip shall be as specified in Fig. 1.

5.1 Graduation Line—The pipet shall have one graduation line located 20 cmm from the pipet tip. The graduation line shall be
located on the clear portion of the tubing and shall extend at least two thirds around the pipet and not exceed 0.4 mm in width.
5.2 Volumetric Designation—The pipet shall be marked 20CMM on the clear portion of the tubing with the markings located
approximately 5 mm above the graduation line.
5.3 Identification—Each pipet shall be marked with the manufacturer’s name or trademark on the white stripe portion of the
pipet. Catalog number markings are optional. All markings shall be permanently fused onto the pipet. The markings shall be amber
or black in color. When tested in accordance to 6.3, the pigmentation shall not discolor. The appearance of the markings, when
viewed by the eye under normal room lighting, shall be the same before and after testing.
5.4 Capacity Deviation—Sahli Hemoglobin pipets are made with maximum capacity deviation of 61.0 % or 62.0 %. The
selected capacity deviation shall be marked on the clear or white stripe portion of the pipet. The capacity of the pipet shall be within
the selected capacity deviation marked on the pipet when tested as specified in 6.2.
