Systems for producing articles from glass tube include a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The systems further include a gas flow system or a suction system for producing a flow of gas through the glass tube during one or more heating, forming, separating or piercing operations. The flow of gas through the glass tube produced by the gas flow system or suction system may be sufficient to evacuate or purge volatile constituents of the glass from the glass tube and/or pierce a meniscus formed on the glass tube during separation, thereby reducing the Surface Hydrolytic Response (SHR) of the interior surface of the glass tube and articles made therefrom.

A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.

Provided are a chemical reaction device able to promote a chemical reaction, and a method for producing same. The chemical reaction device has an optical electric field confinement/chemical reaction container structure obtained by integrating an optical electric field confinement structure for forming an optical mode having a frequency identical to or close to a vibrational mode of a chemical substance involved in a chemical reaction, and a chemical reaction container structure having a space for storing a fluid required for the chemical reaction and containing the chemical reaction, the optical mode and the vibrational mode being vibrationally coupled to promote the chemical reaction.
