How to Program Complex Flow Profiles

The Fusion 100 (infuse only) and Fusion 200 have infuse and withdraw capabilities that allow pumps to achieve basic and multi-step flow profiles. For example, below are some common flow profiles and set-ups on Chemyx syringe pumps.

Example 1: ‘Start/Stop’ Flow Profile

For the start/stop flow profile, the pump starts at a specific flow rate and infuses/withdraws a given volume. The pump stops when the total amount is infused/withdrawn.

Example 2: Stepwise Flow Profile

For the stepwise flow profile, the pump starts at a specific flow rate and stops after infusing/withdrawing the given amount. In this setup, you can also program a delay before each step and a loop to repeat the step.

Example 3: Increase Stepwise Flow

For the increase stepwise flow profile, the pump starts at a specific flow rate and increases in rate within each step, or from one step to the next. In this setup, you can also program a delay before each step and a loop to repeat the step.

Example 4: Decrease Stepwise Flow

Finally, the decrease stepwise flow profile, similar to the ‘Increase Stepwise Flow’, starts at a high rate and decreases in rate within each step, or from one step to the next. In this set up, you can also program a delay before each step and a loop to repeat the step.
