Determine a Target Weight for Each Component
For Part A, which has a specific gravity of 1.2, use a target dispense volume (mL) of 1 rotation (0.01 mL) to
determine a target weight of 12 mg, as shown by the following equation:
Determine Values for RPM 1 (Part A) and RPM 2 (Part B)
The maximum RPM for Part A is 130. If you enter 130 for RPM 1 (Part A), then, based on a mix ratio of 10:3, the
correct RPM for Part B is 39, as shown by the following equation:
For Part B, which has a specific gravity of 1.01, use a target dispense volume (mL) of 1 rotation (0.01 mL) to
determine a target weight of 10.1 mg, as shown by the following equation:

NOTE: The RPM values can be set to any ratio that is equivalent to 130:39 as long as the maximum RPM is not
exceeded (in this example, a maximum of 130). For example, RPM 1 (Part A) could be set to 100 and RPM 2
(PumpB) could be set to 35. Round RPM values to nearest whole integer.
