摘要： A device for conditioning of fluid to minimize pulses from a pump source. A pump drives fluid from a vented fluid reservoir through a system including a combination of an attenuation tank and one or more orifice. Fluid is pumped into a plenum chamber that supplies fluid in a pulse free flow stream. A pressurized head over the fluid in the plenum chamber allows fluid delivery at a selected pressure. A volume sensor monitors the fluid level within the plenum tank and activates the pump if fluid level falls below a specified level.

摘要： A flow cell and flow cytometer in which a nozzle at the end of a flow channel is disposed on a removable substrate held at a registered location on a flow cell. Other elements including illumination optics, light collection optics, and the flow cell may then be positioned at fixed locations and would not require subsequent periodic adjustment. The registered location for positioning the nozzle allows removal and replacement of the nozzle key with the nozzle subsequently positioned in the identical location.
