4.2.1 Syringe mode
Improper heparinization of syringes with liquid heparin may cause false results.
ISE parameters are particularly susceptible.
Please contact Roche customer support regarding this matter.
• Open the flap to the designated syringe position
(half-opened position). The aspiration process is started.
Fig. 2
• Attach the syringe (always remove the cannula first).
Be sure that the needle sufficiently penetrates the interior of the syringe (or ampoule)
in order to remove the sample without air bubbles.
Be sure that the needle does not make contact with the fill port while inserting the nee-
dle into the interior of the syringe.
If the opening of the needle is covered by the fill port, the aspiration is blocked and the
sample is rejected!
If using an ampoule instead of a syringe (during a QC measurement), be sure that the
ampoule does not make contact with the fill port when inserting the needle into the
ampoule. The sharp edge can cause damage to the fill port.
The clot catcher cannot be used in "Syringe mode!"

• The sample is automatically aspirated (it is unnecessary to press any buttons).
