Standard Specification for Disposable Glass Micropipets
ASTM E672-87
Organization:
ASTM - ASTM International
Year: 2024
Abstract: This specification covers two different types of disposable glass micropipets, calibrated “to contain,” used in measuring microlitre volumes of liquids. The pipets made to these specifications shall be fabricated from borosilicate glass (Type I, Class A or B) or soda lime glass (Type II). Pipets shall be of one piece construction and shall meet the specified requirements for shape, dimensions, and capacity. The calibration line and identification markings such as color code marking are illustrated. The methods of reading and setting a liquid meniscus and a mercury meniscus are detailed. Capacity test shall be performed and calculation of micropipet volume shall be taken using the given formula.
