SYSTEM FEATURES OVERVIEW
VIALMIX®RFID is the activation unit designed specifically for DEFINITY® Vial for (Perflutren Lipid Microsphere) Injectable
Suspension, an intravenous ultrasound contrast agent. DEFINITY® is supplied as a liquid-filled glass vial and requires
activation in order to create the lipid-encapsulated microbubbles. The activation rate and duration are controlled by
VIALMIX®RFID through the use of Radio-Frequency Identification (RFID) technology to ensure reproducible activation of
DEFINITY®.
FEATURES OF VIALMIX®RFID INCLUDE:
 Proper Activation of DEFINITY®
A number of digital messages inform the user of an unsuccessful activation. In the event the activation cycle
stopped short of the required activation time or the activation rate deviated from the acceptable range, the user
is alerted via digital messages on the display and an audible alarm. See page 9 for a list of error messages.
IMPORTANT: Shaking the DEFINITY® vial by hand will not activate the agent adequately. Using
VIALMIX®RFID to activate DEFINITY® will ensure proper activation of the agent and consistent product
performance. DO NOT use a DEFINITY® vial if it is not properly activated in VIALMIX®RFID
 Simple Operation
VIALMIX®RFID has two operational buttons on the front panel.
1. A START button for starting the cycle
2. A STOP button for canceling the cycle if needed
VIALMIX®RFID allows for easy loading of the DEFINITY® vial into the vial carrier.
VIALMIX® RFID is equipped with an RFID reader. Once the DEFINITY® vial is loaded in the vial carrier and the
cover is closed, the VIALMIX®RFID will read the RFID tag embedded in the DEFINITY® vial label and will
automatically set the required activation rate and activation time. The appropriate activation time of 45
seconds will appear on the display. The addition of RFID capability to the VIALMIX®RFID is completely transparent
to the user and does not require any additional actions to activate DEFINITY®.
 Safe operation
VIALMIX®RFID contains features that ensure safe operation. These include:
 An automatic shut-off switch that is activated if the cover is opened during operation.
 A STOP button to allow the user to terminate the activation cycle.
 A thermal sensor shut-off to prevent overheating.
