A particle isolation apparatus 100 for isolating particles from a suspension sample, includes a droplet dispenser device 10 for collecting the suspension sample from a carrier substrate 20 and for dispensing droplets onto a target substrate 30, a mechanical pump device 40 being coupled with the droplet dispenser device 10 for loading a dilution liquid into the droplet dispenser device 10 and for aspirating a first portion of the suspension sample into the droplet dispenser device 10, and a syphon pump device 50 being coupled with the droplet dispenser device 10 and being arranged for aspirating a second portion of the suspension sample into the droplet dispenser device 10. Preferably, the droplet dispenser device 10 is configured for dispensing single particle droplets on the target substrate 30. Furthermore, a method of isolating particles from a suspension sample is described.
