Standard Specification for Disposable Glass Culture Tubes
ABSTRACT
This specification covers the requirements for disposable glass culture tubes for use in culturing applications. Disposable glass culture tubes shall be made of type I (borosilicate) or type II (soda-lime) glass. Tube design shall be of one-piece construction. Other requirements shall include top or open end finish requirement, bottom or closed end requirement, residual thermal stress requirement, workmanship, and tube dimensions.
SCOPE
1.1 This specification covers the requirements for disposable glass tubes suitable for general testing and culturing applications in blood banks, hematology, bacteriology, virology, and tissue culture laboratories.
1.2 For practical purposes, the word “disposable” according to this specification and expected product performance expressed in this specification describes those disposable glass culture tubes that are to be used one time only. Any institution or individual who reuses a disposable glass culture tube must bear full responsibility for its safety and effectiveness.
1.3 For packaging standards, choose among the following: Specifications E920 or E921 or Practice E1133.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
