Accuracy/Reproducibility Protocol:

AFTER CALIBRATION

  1. Use a liquid with a known density (water) to test this.
  2. Put some water in the syringe.
  3. Push out 5mL of water onto a scale. Record the mass in grams.
  4. Repeat step 3 nine more times.
  5. Calculate the volume of water that came out each trial. (Volume = Mass/Density)
  6. Compare each trial the volume of each trial to 5mL. Reproducibility = Actual/Theoretical x 100%
