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 &#xb1;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.

Pharmaceutical and medical container

The invention proposes a process for the production of a container for pharmaceutical and medical applications made from glass, preferably from a borosilicate glass, wherein the container is produced by a press-blow process where the container is initially preformed in a pressing step, by making a ram press a dispensed glass drop into a mold that is open at its bottom, and where the parison so produced is given its final form by a subsequent blowing step.

Production of a pharmaceutical container from the melt

The invention proposes a process for the production of a container made from glass, in the form of a hollow body open on both ends for pharmaceutical and medical applications, in particular in the form of a syringe barrel, where a glass drop () is dispensed from a melting unit, is placed into a mold () that is driven to rotate, and is formed by the effect of the centrifugal force, the mold being driven at a rotational speed of at least 5000 rpm, preferably approximately 50000 rpm.
