Abstract: The present disclosure provides a device and a method with which flat glasses with particularly uniform thickness can be obtained. The methods are drawing methods in which a glass ribbon is drawn. In the method an aperture is used which allows a defined very small slit between the glass ribbon and the aperture also in the case of a change of the position of the glass ribbon.

Abstract: A glass syringe barrel is provided that has an at least partially conically shaped upper portion and a longitudinal axis. The glass syringe barrel has a top end through which a liquid can be ejected and a bottom end into which a plunger stopper can be pushed. The glass syringe barrel includes, in a direction from the top end to the bottom end, a cone, a shoulder region, and a body region. The shoulder region has and outer contour that has a concave and substantially circular arc-shaped area ci with an outer radius r1. The outer contour of the glass syringe barrel in the shoulder region is defined by a certain value for r1.

Abstract: A glass container for packaging a pharmaceutical composition including a glass tube with a first end and a second end, the glass tube having a wall thickness dw and an outer diameter dc, a glass bottom with an outer area, the glass bottom closes the glass tube at the first end, and a curved glass heel extending from the outer area of the glass bottom to the first end of the glass tube. The curved glass heel is defined by an outer radius ro, an inner radius ri, and a thickness of the glass dh in the curved glass heel and wherein: [100×(dh3×ri)/(dw ×dc2)]+(4.4 mm2/dc)>0.55 mm.

Abstract: A container for pharmaceutical and medical applications made from glass, preferably from a borosilicate glass. The container is formed in the shape of a hollow body open at both its ends with a cylindrical portion having a wall thickness tolerance of maximally ±0.2 mm. The borosilicate glass has a nominal boron content that drops by less than 40% relative to the nominal value at all of the surfaces of the container.

Abstract: A glass article is provided that has two plane-parallel main sides, a thickness between the two plane-parallel main sides of less than 3.0 mm, an average near-surface level of damage (ONSL) on each of the two plane-parallel main sides, and an average location-thickness variation (ODS) normalized with respect to the thickness on the specified measuring area. The average near-surface level of damage is less than 2000 damages with an extension of less than 1.0 μm. The specified measuring area is 2×2 mm2. The average location-thickness variation (ODS) normalized is less than 10 nm per Rm thickness of the glass article. The average location-thickness variation (ODS) is a difference between a highest thickness and a lowest thickness within the specified measuring area.
