  • Acid
  • Plastic Container for Solution
  • Deionized Water (18.2 megohm - cm at 25°C) also called Milli-Q
  • Goggles
  • Gloves
  • Graduated Cylinder
 Acid dilution preparation; link to larger image
Fill the plastic container half full with Milli-Q water. Fill container part way with water; link to larger image
Pour acid into graduated cylinder to desired amount. Measure acid into graduated cylinder
Add the acid to the water. Pour acid into container
Fill the plastic container to the fill line with Milli-Q water. Fill with water to fill line
