Claims4
A microfluidic system for processing a sample, the system comprising:
- a transfer capillary pipette comprising a sample transfer body adapted to contain the sample, said sample transfer body having a first end and a second end;
- and
- a cartridge defining a linear receiving chamber having a first end and a second end, and an output chamber connected to the first end of the linear receiving chamber, said linear receiving chamber configured to receive said sample transfer body,
- wherein said first end of said sample transfer body is positioned in said output chamber when the sample transfer body is positioned within said linear receiving chamber,
- wherein said cartridge is configured to rotate about a center of rotation,
- wherein said linear receiving chamber is positioned non-radially with respect to said center of rotation of said cartridge, and
- wherein said output chamber is positioned closer to said center of rotation of said cartridge than said second end of said linear receiving chamber is positioned to the center of rotation of said cartridge.
