Disclosed is a method for subjecting adherent cells to at least one electric field, in which the electric field is generated by applying a voltage to at least two active electrodes, wherein at least three electrodesare provided, and wherein at least two electrodesare active electrodeswhen the voltage is applied in order to generate a first electric field, and in which at least one second electric field is generated, wherein at least one of the two previously active electrodesis a potential-free electrodewhen the voltage is applied. Also disclosed is a devicecomprising at least three electrodes, which are connected to at least one voltage source by means of at least one switching device, wherein at least five electrodesare connected to the at least one voltage source by means of four switching devices, wherein at least two electrodesare connected to the voltage source by means of a common switching device. In conjunction with the method described above, the device according to the invention allows the efficient and uniform treatment of adherent cells using an electric field, wherein the switch between active and potential-free electrodes can be carried out quickly and safely using a lower number of switching devices.

A method for further processing of a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with tube-specific data for the glass tube semi-finished product; reading the tube-specific data for the glass tube semi-finished product; and further processing of the glass tube semi-finished product including a step of thermal forming carried out at least in sections. At least one process parameter during the further processing of the glass tube semi-finished product including the step of thermal forming carried out at least in sections is controlled as a function of the tube-specific data for the glass tube semi-finished product. In this way, the further processing can be matched more efficiently to the particular characteristics of a glass tube semi-finished product to be processed or a particular subsection thereof, and the relevant characteristics of the particular glass tube semi-finished product do not need to be measured again.

A method and a device for optical examination of transparent bodies made of plastic, glass, or glass ceramic are provided. The examination is carried out by contactless detection and measurement of the body using optical imaging devices. For this purpose, a plurality of individual images are taken of the body during the examination in different positions relative to the imaging device, which are subsequently analyzed.
