Constant Rate Profile - KD Scientific KDS LEGATO 100 User Manual

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.
