5. Repeat steps 3 and 4, but include Filter Cap (if present).

By the end, you should have an insert volume and two cup volumes (one with cap and one without cap). If cap is not present, you should have one cup volume.

 

For 10 cm3 insert, cup and cap

1. Place 10 cm3 insert with no cup and no cap in chamber.

2. Navigate to Settings > Inserts > Measure Volume. Select Insert and measure.

By the end, you should have an insert volume and two cup volumes (one with cap and one without cap).

 

For 100 cm3 cup with filter cap

  1. Place 100 cm3 reference (51 cm3 Stainless Steel [SS] sphere) in 100 cm3 cup and cap in chamber.
  2. Navigate to Settings > Inserts > Measure Volume. Select Cup, then choose Reference (51 cm3) and Insert (-----------), then measure.

  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 100 cm3, 35 cm3, or 10 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 100 cm3 chamber with a 16.7599 cm3 sphere:

0.0002 x (100 + 16.7599) = 0.0234 cm3

Acceptable volumes would be 16.7599 ± 0.0234 cm3.

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