At least one glass tube has an azimuthal wall thickness deviation WTD of not more than 6.0%, the azimuthal wall thickness deviation being determined based on a lowest wall thickness value and a highest wall thickness value measured within a cross-section of the at least one glass tube, the azimuthal wall thickness deviation WTD being calculated according to the following formula:

Glass tube

A glass tube, such as a glass tube for the production of containers for storage of pharmaceutical compositions, facilitates production of pharmaceutical containers with high quality. The glass tube has a relative cross-sectional area deviation defined as is less than k*x+t. QFis the highest cross-sectional area and QFis the lowest cross-sectional area of at least two cross-sections of the glass tube, the cross-sections being spaced apart from each other along a length of the glass tube, and k is 0.0023 m, t is less than 0.15 mm/m and x is
