摘要： The fluidic system with an unclogging feature of the preferred embodiment includes a flow channel, a sheath pump to pump sheath fluid from a sheath container into an interrogation zone, and a waste pump to pump waste fluid from the interrogation zone into a waste container. The sheath pump and/or the waste pump draw sample fluid from a sample container into the interrogation zone. The fluidic system also includes a controller to adjust the flow rate of the sample fluid from the sample container into the interrogation zone. The pump and controller cooperate to propagate a pulsation through the flow channel from the pump if the flow channel is clogged. The fluidic system is preferably incorporated into a flow cytometer with a flow cell that includes the interrogation zone.

摘要： The preferred embodiments of the invention is an optical system for a flow cytometer including a flow channel with an interrogation zone, and an illumination source that impinges the flow channel in the interrogation zone from a particular direction. The optical system preferably includes a lens system and a detection system. The lens system preferably includes multiple lens surfaces arranged around the flow channel and adapted to collect and collimate light from the interrogation zone. The detection system preferably includes multiple detectors adapted to detect light from the lens system. Each detector preferably includes a local filter that independently filters for specific wavelengths. Thus, the user may easily swap the filters in any order to achieve the same detection parameters.
