A syringe made of borosilicate glass and having a cone for fastening or mounting of transfer adapters and needles is provided. The cone includes a coating that increases roughness. The coating has structure-forming particles are embedded in a glass matrix and is free of Pb, Cd, Hg and Cr.

Borosilicate glass syringe with cone coating that increases surface roughness

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.

Production from the melt of a container made from glass

A device and a method for thermal pre-stressing lengthy hollow objects, in particular glass tubes, are disclosed. The device comprises a heating device, a fixture for receiving an object, and a coolant feed device comprising an outer coolant feed unit with a plurality of nozzles for feeding coolant against an outer surface of the object, and further comprising an inner coolant feed device for feeding coolant against an inner surface of the object.
