Device for coupling a cartridge for a lab-on-a-chip analysis device, lab-on-a-chip analysis device and method for coupling a cartridge for a lab-on-a-chip analysis device

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.
