10143974 DURAN GL 45 Blue Laboratory Bottle With Screw Cap and Pouring Ring 500 mL
Since its introduction in 1972, DURAN® Original GL laboratory bottles have grown to be the industry benchmark for multipurpose laboratory bottles. The bottles are made of high-purity, transparent, USP/EP Type I borosilicate glass 3.3, which is recognized for its great resistance to chemical assault and outstanding thermal performance. Long operating life is provided by the use of high-performance materials and a sturdy ISO 4796-1 design. The bottles have a permanent white enamel marking area and an easy-to-read graduated volume scale. For manufacturing lot traceability, each bottle has a permanent retrace code. For use up to 140 °C, DURAN® Original GL bottles come complete with the recognizable blue polypropylene cap and drip-free pouring ring. At 121 or 134 °C, all components can be thoroughly autoclaved.

PP, BORO 3.3
A high maximum use temperature, virtually inert behavior, great light transparency, and little thermal expansion are all characteristics of borosilicate glass 3.3. The linear coefficient of expansion of borosilicate glass 3.3 is 3.3 x 10−6 K−1.
This is a lot number that was printed on the item during production and is used to identify the production unit, the production work order, and to track the materials that were used.
