Abstract: A method for operating an analysis device for carrying out an analysis process, more particularly by using a polymerase chain reaction, includes providing a cartridge having a microfluidic channel-and-chamber structure. At least one film bag containing a process liquid is disposed in a stick-pack chamber of the cartridge. In an opening step the stick-pack chamber or stick-pack chambers are heated to a temperature of 80 to 130 degrees Celsius, and in the opening step the cartridge rotates at a rotational speed of 20 to 80 Hz. A cartridge and an analyzer are also provided.

Abstract: A method of transporting magnetic particles enables magnetic particles to be transported between a plurality of microfluidic chambers which are connected to one another via a fluidic connection on a radially inner side, and are fluidically separated from one another on a radially outer side. Magnetic forces and centrifugal forces are exploited to transport magnetic particles from one chamber to another across phase boundaries.

Abstract: A stator blade carrier, particularly for a gas turbine, is provided. The stator blade carrier includes a number of axial segments and is intended to attain a particularly high degree of operational reliability and long service life. To this end, two neighboring axial segments are connected to a number of tie rods, each enclosed by a support tube, wherein a spherical disk is arranged on at least one end of the respective support tube and mounted in a conical socket supported on the respective axial segment.

Abstract: A device for producing a dilution series from a solution to be diluted, which contains a substance to be diluted, and a dilution solution, includes a body of rotation, a drive configured to subject the body of rotation to rotations having different rotation protocols, and a controller configured to control the drive so as to subject the body of rotation to the different rotational frequencies. A first mixing chamber and a second mixing chamber are connected via a fluidic connection which enables producing, in the first mixing chamber, a first mixture having a first dilution ratio, transferring a partial volume of the first mixture into the second mixing chamber, and there producing a second mixture having a second dilution ratio.
