Abstract: In a device for coupling a cartridge for a lab-on-a-chip analysis device, the cartridge has at least one pneumatic port and at least one reagent chamber. The device has a receiving region and a clamping unit. The receiving region is shaped to receive the cartridge. The clamping unit includes a pneumatic interface for pneumatically contacting the pneumatic port and a punch for insertion into the reagent chamber. The clamping unit is arranged adjacent to the receiving region and is designed to perform a first translatory motion toward the receiving region in order to bring the pneumatic interface into contact with the pneumatic port. Furthermore, the clamping unit is designed to perform a second translatory motion toward the receiving region following the first translatory motion in order to insert the punch into the reagent chamber.

Abstract: In a method for the desorption of nucleic acids from a sample, in order to simplify the desorption of nucleic acids from the sample, a solid phase is repeatedly rinsed with an elution buffer in a microfluidic system, in order to elute nucleic acids bonded to the solid phase from the solid phase in the microfluidic system.

Abstract: A microfluidic device for analysing nucleic acids includes a pump unit with a pumping volume, a filter unit for receiving a lysate, and a reaction chamber. The pump unit, the filter unit and the reaction chamber are arranged in the stated order in a pump direction of the pump unit. The microfluidic device is configured to pump an elution medium via the pump unit into the filter unit for elution and subsequently into the reaction chamber for further treatment.

Abstract: A filter device for an optical module for a lab-on-a-chip analysis device, in which the optical module has a light path, includes a support element, a filter support, and a drive device. The support element can be mounted in the optical module. The filter support is arranged so that it can move on the support element. The filter support also has a first filter region and a second filter region. The drive device is configured such that the filter support can move between a first position in which the first filter region is arranged in the light path, and a second position in which the second filter region is arranged in the light path.

Abstract: A microfluidic device for analyzing samples includes at least two fluidic pathways for receiving samples and at least one capture area. The at least one capture area is configured for a detection unit for measuring light, and is configured to capture light emitted from samples in the at least two fluidic pathways, across the capture area.

Abstract: A processing system includes a processing unit configured to process a cartridge, in particular a microfluidic cartridge, and is further configured to process a biological sample received in the cartridge. The processing unit includes a computing unit configured to compare input or read in sample data with input or read in first cartridge data in order to determine a compatibility of the sample with the cartridge. The computing unit is further configured to output a first error message in response to a determination of incompatibility between the sample and the cartridge. A method includes using the processing system to determine a compatibility between a sample and a cartridge.

Abstract: A method for actuating an analysis device for running an analysis on a sample material includes reading a user parameter, which represents an analysis to be carried out on the sample material, and loading a plurality of actuation commands for at least one analysis running unit of the analysis device from a command library. The method further includes actuating the at least one analysis running unit using the actuation commands in order to analyze the sample material.

Abstract: A microfluidic device includes a chamber substrate, a cover substrate, a flexible membrane, and a punch unit. The chamber substrate includes a fluid chamber configured to receive a fluid and having a fluid chamber opening. The cover substrate includes a punch opening lying opposite the fluid chamber opening. The flexible membrane is positioned between the chamber substrate and the cover substrate, and spans the punch opening and the fluid chamber opening. The punch unit is configured to move into the fluid chamber through the punch opening in order to deflect the flexible membrane into the fluid chamber so as to enable the fluid to flow out of the fluid chamber when fluid is received in the fluid chamber.

Abstract: A film bag for a microfluidic analysis system includes a film bag bottom, a film bag opening arranged opposite the film bag bottom, and a peel seam arranged between the film bag bottom and the film bag opening. The peel seam is formed to produce a closed reagent receiving region between the peel seam and the film bag bottom and a tube between the peel seam and the film bag opening. The reagent receiving region has a reagent receiving length extending between the peel seam and the film bag bottom. The tube has a tube length extending between the peel seam and the film bag opening. The tube length is at least five percent of the reagent receiving length.

Abstract: A housing for a chip laboratory analysis device has a cartridge opening for introducing a cartridge with material to be analyzed into the chip laboratory analysis device. The housing also includes a rear side with a connection opening for connecting a cable for power supply to the chip laboratory analysis device. In addition, the housing has a standing surface side with a maintenance interface for maintaining the chip laboratory analysis device. The standing surface side is shaped in order to function as a standing surface for the chip laboratory analysis device when the chip laboratory analysis device is in operation. The rear side is shaped in order to function as a further standing area for the chip laboratory analysis device when the cable is removed from the connection opening and when the chip laboratory analysis device is being maintained.
