10 World Precision Instruments
Once the desired aliquot volume is selected, then each time the Inject
button is depressed, an audible beep is heard and the aliquot is dispensed.
Pressing Inject before the first aliquot is dispensed will not produce a second
injection. Wait for the beep (which indicates the injection is complete) before
beginning a second injection.
Setting the Aliquot Volume and Injection Speed
Aliquot volumes and injection speeds are controlled by the positions of
the DIP switches located on the side of the control box. Table 1 lists the
DIP switch settings to use for DIP switches 1–4 to select the various aliquot
volumes. (“U” = up, “D” = down). DIP switch 5 determines the fast injection
and fill rates.
• Up (Fast) = 46nL/s
• Down (slow) = 23nL/s
TIP : To set the DIP switches, use a ball point pen or a jeweler’s flat head
screw driver.
NOTE : DIP switch settings for the Nanoliter 2000 are completely different
from the previous model, the Nanoliter Injector A203.
