ABSTRACT:
Capsules, entrained in a fluid medium, are directed into a channel deflection system designed to enable evaluation and separation of successfully encapsulated cellular material from the blanks and other debris. Preferably, the fluid media with the capsule is introduced into a first or main channel and the capsules first pass one or more windows in the main channel for evaluation that is conducted by electromagnetic and/or optical means. Preferably, the evaluation results in the selection of acceptable capsules and subsequent removal of the blank capsules from the medium through the use of multiple jets that gently redirect the acceptable capsules into an alternate channel. Preferably, fluid is also introduced into the alternate channel and the main channel and the alternate channel are arranged such that there is a window defined between the two channels where the fluid flow between the two channel is directly adjacent and the jet deflection system can selectively deflect capsules across this window between the two channels with a minimum amount of force and a minimum of turbulence created in either channel.
