FLUIDICS SYSTEM FOR FLOW CYTOMETER

摘要

A fluidics system for a flow cytometer is disclosed. In some examples, the system includes a junction disposed between a pump and a sample probe. In some examples, the pump is a peristaltic pump. A pulse-attenuation system is also disclosed. A method for removing gaps caused by pulsations in output data is also disclosed. A fluidics system and method for processing samples in parallel is also disclosed. A fluidic system for a flow cytometer that includes an agitator for agitating a sample is also disclosed. A sheath fluid transfer system of a fluidic system for a flow cytometer is also disclosed.

主权项

1. A flow cytometer comprising:
a flow cell for passing particles in a sample; a sample probe to aspirate the sample; a switching valve connected to the flow cell, the sample probe, a first tube section, and a second tube section, the switching valve having a first and a second selectable position, wherein the switching valve forms a fluid connection between the sample probe and the first tube section and between the flow cell and the second tube section when the switching valve is in the first position, and wherein the switching valve forms a fluid connection between the sample probe and the second tube section and between the flow cell and the first tube section when the switching valve is in the second position; and a first pressure source connected to the first tube section, and a second pressure source connected to the second tube section, wherein the first pressure source is configured to cause a first sample to flow from the sample probe to the first tube section and the second pressure source is configured to cause a second sample to flow from the second tube section to the flow cell when the switching valve is in the first position.
