Abstract: A method for monitoring the use of a consumable in a disposable design in multiple analyzers is disclosed. The method provides a disposable consumable; uses the consumable as intended during operation of the first analyzer; and collects usage-relevant information for the consumable concerning the intended use of the consumable during operation of the first analyzer. Usage-relevant data derived from the usage-relevant information is stored in a memory unit assigned to the consumable. The consumable may be removed and again provided in the first or second analyzer. The first or second analyzer partially reads the usage-relevant data from the memory unit, evaluates the usage-relevant data, and derives control signals concerning the permissibility and/or type of a further intended use of the consumable during operation of the analyzer as a reaction to the evaluation of the read usage-relevant data.

The device according to the invention comprises the following components: a cartridge with a plurality of containers, which can be connected to an intake system of an analyzer, each of which contains a measurement fluid with known measurement parameter values; a storage unit assigned to the cartridge for storing the measurement parameter values of the measurement fluids and data relevant for the CV process of the analyzer to be verified; a docking or intake area at or in the analyzer for receiving the cartridge with a data path for reading the storage unit; an evaluation unit typically housed in the analyzer for evaluating the values measured by the analyzer; and an output unit for printing an evaluation protocol.

Abstract: A peristaltic pump is provided comprising squeezing elements moved by at least one actuator, which squeezing elements act on a tube in which a medium is conveyed, with the squeezing elements successively getting into and out of a squeezing engagement with the tube. A process for controlling the peristaltic pump comprises measuring over time a fluidic parameter representative for the flow rate of the medium through the tube, determining the relative undulation of the flow rate of the medium from the measured temporal course of the fluidic parameter, and smoothing the undulation by adjusting the progression speed of the squeezing elements on the basis of the determined undulation of the flow rate.
