“0.500 mL/drops”.

Calibration (Generic Process using SPARKvue on a
Computer or Tablet)
1.
Attach the Drop Dispenser (syringe, two stopcocks and
drop tip) to a support rod.
2.
Fill the syringe with titrant. Put a beaker under the Drop Dispenser to catch the titrant.
3.
Open both stopcock valves and adjust the valve on the bottom stopcock so that the drops fall at a rate of about
1 drop per second. Close the top valve after the rate is achieved. Discard the titrant as directed by your
instructor.
4.
Align the drop tip with the rectangular window in the Wireless Drop Counter. Put a graduated 10 mL cylinder
under the Drop Counter window so it can catch drops from the drop tip and give you a measure of the volume.
5.
Start SPARKvue.
