Hypothesis

The new rotor design can efficiently process a bulk aliquot of whole blood into multiple microliter aliquots of plasma.

Conclusion

The CPA-2 can produce multiple plasma aliquots with precision and accuracy comparable to mechanical pipettes.

Supporting Evidence

  • The CPA-2 can produce discrete, microliter volumes of plasma with accuracy similar to mechanical pipettes.
  • Capillary tubes used in the CPA-2 were capable of delivering microliter volumes with precision.
  • Different capillary volumes can be selected for specific chemical assays.

Takeaway

This study shows a new machine that can quickly turn a big drop of blood into many tiny drops of plasma for testing.

Methodology

The CPA-2 rotor processes a bulk aliquot of blood into multiple plasma aliquots using centrifugal force and capillary action.

Limitations

The device is limited to producing a batch of single aliquots from single aliquots of whole blood.

Participant Demographics

Blood samples were collected from healthy subjects.
