First Claim
Patent Images
1. A particle sorting system comprising:
- a cartridge including;
a particle sorting component configured to receive a stream of particles and to individually sort on a particle-by-particle basis the stream of particles into selected particles having a predetermined characteristic and unselected particles not having the predetermined characteristic;
a particle source upstream of and in fluid communication with the particle sorting component for providing particles to be sorted to the particle sorting component;
a first chamber downstream of and in fluid communication with the particle sorting component for collecting the selected particles;
a second chamber downstream of and in fluid communication with the particle sorting component for collecting unselected particles; and
one or more sealing elements configured to completely seal the cartridge during a particle sorting operation so as to prevent liquid transfer to and from the interior of the cartridge.

Abstract
A single disposable cartridge for performing a process on a particle, such as particle sorting, encapsulates all fluid contact surfaces in the cartridge for use with microfluidic particle processing technology. The cartridge interfaces with an operating system for effecting particle processing. The encapsulation of the fluid contact surfaces insures, improves or promotes operator isolation and/or product isolation. The cartridge may employ any suitable technique for processing particles.
