Abstract: The present invention belongs to the field of in-vitro diagnostics. Within this field, it particularly concerns the amplification of at least a first target nucleic acid that may be present in at least one fluid sample using an internal control nucleic acid for qualitative and/or quantitative purposes and at least one external control nucleic acid in an aqueous buffer. It further provides an analytical system comprising an internal control nucleic acid for qualitative and/or quantitative purposes and at least one external control nucleic acid in an aqueous buffer.

Abstract: Modular flow cells, devices with modular flow cells, and methods of sequencing using modular flow cells, as well as systems and kits including modular flow cells, are described, permitting sequencing wherein less than the full capacity for sequencing is desired.

Abstract: The present invention provides a method for the amplification of at least a first and a second target nucleic acid that may be present in a fluid sample. The invention further provides a kit and an analytical system for carrying out said amplification.

Abstract: A telescopic ladder having two mutually adjacent side rails and rungs disposed between the side rails, wherein the side rails include a plurality of substantially tubular, telescoping side rail portions and mutually adjacent side rail portions connected to one another by a rung wherein the side rail portions have a locking unit with which the side rail portions can be locked against the respectively next lower side rail portion in the extended setting.
