Biological sample processing system and microfluidic cartridge therefor

Biological sample processing system comprising an imaging unit comprising a digital image processing system and at least one microscope including at least one lens, a sample processing station comprising a handling platform including a support and a displacement mechanism for moving the support, and a sample processing unit mounted on the handling platform, the sample processing unit comprising a tissue slide holder for mounting thereon a tissue slide with a biological sample fixed thereon and a microfluidic cartridge holder for mounting a microfluidic cartridge thereon, the tissue slide holder coupled to the microfluidic cartridge holder via a coupling allowing the microfluidic cartridge and the tissue support to be mounted and removed from the sample processing unit in an opened position and in a closed position for the tissue support to be in sealing contact with the microfluidic cartridge, wherein the sample processing station comprises a plurality of said sample processing units mounted on the handling platform and moveable from a position allowing mounting of the tissue slide, respectively microfluidic cartridge, or removal thereof, to a position in which a viewing window in the microfluidic cartridge holder is positioned in alignment with the lens of said at least one microscope,

• wherein each sample processing unit comprises a clamping mechanism including a locking mechanism and a pressure actuator configured to apply pressure on the tissue support against the microfluidic cartridge in a closed position.
