Abstract
Processes for preparing controlled samples of particles, including microorganisms and cells are described. A sample of particles is provided and separated into a predetermined number of desired particles by particle separation means. The predetermined number of particles is dispensed into a receptacle or onto a surface in accordance with a sorting instruction, with the receptacle or surface being positioned by collecting means so as to receive the dispensed particles. A sorting instruction from the particle dispensing means activates the collecting means such that when a sorting instruction has been actuated, so as to deliver a predetermined number of particles into a receptacle or onto a surface which is positioned accurately for sufficient time to collect all sorted particles, the collecting means advances and positions a subsequent surface or receptacle for receipt of particles, the collector means thereafter signaling the particle separation means to commence the next sorting instruction.
