Abstract
An amber pharmaceutical glass container is provided, wherein the amber glass has a transmission throughout a wavelength range of from 290 nm to 450 nm of 25% or less, measured at a thickness of 1.0 mm, and a transmission throughout a wavelength range from 590 nm to 610 nm of 45% or more measured at a thickness of 1.0 mm. A method for producing such an amber pharmaceutical glass container and the use of such an amber pharmaceutical container for storing a pharmaceutical or cosmetical composition or drug and preferably for storing antibody-drug-conjugates is also provided.
Claims14
A method for producing an amber pharmaceutical glass container, the amber pharmaceutical glass container having a transformation temperature Tg, the method comprising the steps of:
- a) providing an amber glass tube;
- b) hot forming the amber glass tube into an amber glass container;
- c) heating the amber glass container at a temperature of between Tg +5° C. to Tg +50° C.;
- and
- d) cooling the heated amber glass container of step c) to a temperature of between Tg −60° C. to Tg −10° C. at a speed of between 0.8° C./s to 4° C./s per 1.0 mm wall thickness of the amber glass container to obtain the amber pharmaceutical glass container.
An amber pharmaceutical glass container comprising amber glass, the amber glass having a transmission throughout a wavelength range of from 290 nm to 450 nm of 25% or less, measured at a thickness of 1.0 mm, the amber glass further having a transmission throughout a wavelength range from 590 nm to 610 nm of 45% or more measured at a thickness of 1.0 mm.
A method for producing an amber pharmaceutical glass container comprising:
- employing Fe2O3 and TiO2 in a borosilicate glass as a temperature dependent coloring system, wherein the Fe2O3 and TiO2 are used in a ratio of between 1:3.00 to 1:5.00 based on the weight of the oxides.
