1. Preheat drying oven to 110 ºC.
2. Verify that the ultrasonic cleaning unit is clean.
3. Use 5 grams of Alconox (or other suitable detergent) per 500 ml of warm water and fill the
ultrasonic unit with enough water to cover the sample tubes and filler rods (if used). If too
much detergent is used, it may be difficult to rinse from the sample tubes. Ensure the deter-
gent is dissolved before placing the sample tubes and filler rods into the water.
4. Fill the sample tubes with warm water and place them in the ultrasonic cleaning unit, then
place the filler rods in the unit. Turn on the ultrasonic cleaning unit for approximately fifteen
minutes.
