The following table outlines the tasks to properly prepare for an analysis and the location of the task

Cleaning and Labeling Sample Tubes
Sample tubes and filler rods must be clean and dry before samples are added and weighed. The follow-
ing table indicates which materials are supplied by Micromeritics and which are supplied by the user.
The procedures following the table are recommended.
1. Preheat drying oven at 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). Ensure the
detergent is dissolved before placing the sample tubes and filler rods into the water. If too much
detergent is used, it may be difficult to rinse from the sample tubes.
