Constant Rate Profile

The Constant Rate profile is used to run the pump at a

defined flow rate and for a specific pumping mode

(infuse or withdraw) up to a target volume or for a

defined time period.

Constant Rate Pump Operation Profile

When creating or editing a Constant Rate profile, you

will define three primary operating parameters:

The Flow Mode defining the direction of flow:

infuse or withdraw

The Flow Rate to define the rate of uptake or

dispensing

The Target Volume or Run Time that determine how

long the pump will operate at the set rate

When creating or editing a Constant Rate profile, you

can set the rate in ml, µl, nl or pl units of volume using

sec, min or hr as the units of time. The system

automatically calculates a minimum and maximum flow

rate based on the syringe selected or custom-defined.

The min/max values are made available as button

selection options on the Set Infuse and Withdraw Rate

screens.
