Transportable flow cytometer

1 . A flow cytometer to be used with a flow cell defining an interrogation zone comprising:

a fluidic system adapted to draw a sample fluid into the interrogation zone;

a light source adapted to emit light toward the sample fluid in the interrogation zone;

an optic system adapted to collect and detect at least one of a scattered light and a fluorescent light from the interrogation zone;

a processor coupled to the optic system; and

wherein the flow cytometer, if properly boxed and labeled, complies with the parcel post requirements of the United States Postal Service.

2 . The flow cytometer of claim 1 , wherein the fluidic system includes a sheath pump adapted to pump sheath fluid from a sheath container into the interrogation zone, a waste pump adapted to pump waste fluid from the interrogation zone into a waste container, wherein at least one of the sheath pump and the waste pump draw sample fluid from a sample container into the interrogation zone.

3 . The flow cytometer of claim 2 , wherein the sheath pump is a peristaltic pump.

4 . The flow cytometer of claim 3 , wherein the fluidic system also includes a fluidic capacitor located between the sheath container and the interrogation zone and adapted to temporarily expand and accumulate the sheath fluid to attenuate pulsations within the sheath fluid.

5 . The flow cytometer of claim 1 , wherein the light source is a solid-state laser device.

6 . The flow cytometer of claim 1 , wherein the optic system includes a lens system with at least three lens surfaces arranged around the interrogation zone, each lens surface adapted to collect at least one of a scattered light and a fluorescent light from the interrogation zone.

7 . The flow cytometer of claim 6 , wherein the lens surfaces are truncated aspherical lenses.

8 . The flow cytometer of claim 7 , wherein the optic system is a series of photomultiplier tube devices, each photomultiplier tube device having an integrated preamplifier.

9 . The flow cytometer of claim 1 , wherein the optic system includes an optical device adapted to collect and partition light into a first channel and a second channel, wherein the first channel and the second channel are substantially similar light from a substantially singular orientation of the interrogation zone; a first waveguide adapted to guide the first channel from the optical device to the light detector system without substantial interruption; and a second waveguide adapted to guide the second channel from the optical device to the light detector system without substantial interruption.

10 . The flow cytometer of claim 1 , wherein the optic system includes a series of photodiodes.

11 . The flow cytometer of claim 1 , wherein the processor includes a first circuit board connected to the light source and a second circuit board connected to the light detector.

12 . The flow cytometer of claim 1 , wherein the flow cytometer further includes an interface connected to the processor and adapted to communicate information between a host computer and the processor.

13 . The flow cytometer of claim 1 , further comprising a chassis, wherein the chassis substantially contains the optic system, the light source system, the fluidic system, the light detector, and the processor.

14 . The flow cytometer of claim 13 , further comprising a power supply unit adapted to transform power from a power grid, wherein the power supply unit is substantially contained within the chassis, and wherein the power supply unit substantially conforms to one of the AT and ATX power supply standards.

15 . The flow cytometer of claim 1 , wherein the flow cytometer weighs equal to or less than 70 pounds.

16 . The flow cytometer of claim 15 , wherein the flow cytometer weighs equal to or less than 35 pounds.

17 . The flow cytometer of claim 1 , wherein the flow cytometer measures equal to or less than 130 inches in combined length and girth.

18 . The flow cytometer of claim 17 , wherein the flow cytometer measures equal to or less than 108 inches in combined length and girth.

19 . A method of supplying a flow cytometer, comprising the following steps:

providing a flow cytometer to be used with a flow cell defining an interrogation zone, wherein the flow cytometer includes a fluidic system adapted to draw a sample fluid into the interrogation zone, a light source adapted to emit light toward the sample fluid in the interrogation zone, an optic system adapted to collect and detect at least one of a scattered light and a fluorescent light from the interrogation zone, and a processor coupled to the optic system;

properly boxing and labeling the flow cytometer; and

shipping the boxed and labeled flow cytometer via the United States Postal Service.

20 . A method of servicing a flow cytometer having a fluidic system, a light source, an optic system, and a processor, the method comprising the following steps:

receiving the flow cytometer from a user via the United States Postal Service; and

servicing the flow cytometer.

21 . The flow cytometer of claim 13 , further comprising a handle adapted to facilitate lifting of the flow cytometer.

22 . The flow cytometer of claim 13 , further comprising a power supply unit adapted to transform power from a power grid and having a first portion that is contained within the chassis and a second portion that is separate from the chassis.
