Abstract
A glass tube has a center axis, where for the glass tube a specific cross-sectional plane is defined which includes the center axis and which is parallel to the center axis. Within the specific cross-sectional plane, for each pair of outer diameters d1 and d2 of the glass tube at any two arbitrarily selected first axial position x1 and second axial positions x2 along the center axis, respectively, the following relation is 60 or smaller: |(d2−d1)/(x2−x1)|*(10{circumflex over ( )}6 mm)/d1.
