  1. After measurement, label descriptively to distinguish between standard cup and cup with filter.

Note: The cup with filter is slightly shorter than the standard cup. If the filter is placed on the standard cup, the AccuPyc chamber may not close and seal properly.

By the end, you should have one cup volume (cup with cap).

 

Set up methods

  1. Create your methods and select the appropriate insert and cup.
  2. When using a 10 cm3, 3.5 cm3, or 1.0 cm3 sample cup, you can analyze the reference spheres as samples and compare the measured volume to the certified values.

Acceptance criteria

Micromeritics tolerance is:

0.02% x (nominal chamber volume + volume of reference)

For example, a nominal 10 cm3 chamber with a 2.4250 cm3 sphere:

0.0002 x (10 + 2.4250) = 0.0025 cm3

Acceptable volumes would be 2.4250 ± 0.0025 cm3.

End user may establish internal acceptance criteria based on internal needs.
