Fusion Series User Manual
Target Transfer Volume
The Volume field represents the total volume of liquid that the pump will transfer (infusion or
withdrawal) before stopping. The amount of time that the pump will run with the set target
volume can be determined by dividing the volume by the flow rate.
The value entered can be any integer or decimal within the limits for the syringe. The min/max
volume limits can be found in the blue bar at the top of the screen when the Volume field is
selected. Any entered value beyond these limits will be automatically adjusted to the minimum
or maximum limit, whichever is closer. The total number of decimal places is limited to five.
The volume can be stated in units of mL or μL. The units used for the volume are dependent
upon the set units of volume for the flow rate in the Options screen.
To continuously run the pump and use the entire volume of the syringe, users can set the
volume to the total volume of the syringe or to the maximum limit. However, users are strongly
encouraged to set the safety collar/bar (see Adjusting the Safety Collar) so that the pump does
not potentially ruin the syringe.
Important Note
The maximum volume limit for a syringe assumes that the length of the syringe is the length of
the pump. Therefore, this maximum volume limit is almost always larger than the actual
volume the syringe can hold.
Infusion/Withdrawal (Fusion 200 only)
The Fusion 200 is capable of both infusion and withdrawal. On Fusion 200 systems, an
Infusion/Withdrawal toggle button should appear to the right of the Volume field. The text and
arrow direction on the button indicates the mode that is currently set and direction that the
pusher block will move upon starting the run. Tapping the button will switch between the two
modes.
Flow Rate
The Flow Rate field indicates how fast the pusher block will move. The amount of time that the
pump will try to run can be determined by dividing the set volume by the flow rate.
The value entered can be any integer or decimal within the limits for the syringe. The min/max
flow rate limits can be found in the blue bar at the top of the screen when the Rate field is
selected. Any entered value beyond these limits will be automatically adjusted to the minimum
or maximum limit, whichever is closer. The total number of decimal places is limited to five.
The rate can be stated with four different units: mL/min, mL/hr, μL/min, and μL/hr. Adjusting the
units will affect the min/max limits for the Rate field. The units for rate can be set in Options.
