Abstract
A method of dispensing a particle mixture and a reagent fluid cartridge are presented. The cartridge comprises a first reservoir partially filled with reagent fluid, a second reservoir partially filled with particles, a pumping chamber, a first pumping chamber conduit connecting the first reservoir and the pumping chamber, a second pumping chamber conduit connecting the second reservoir and the pumping chamber, an outlet for dispensing reagent fluid and particles from the cartridge, an outlet conduit connecting the outlet to the pumping chamber, and a valve sealing the outlet conduit. The method comprises closing the valve, applying a force to the plunger to transport a first defined volume of reagent fluid and second defined volume of particles into the pumping chamber to form a mixture of reagent fluid and particles, opening the valve, and forcing the mixture from the pumping chamber using the plunger to dispense the mixture from the outlet.
