Safety Filter, AO-5000 and AO-10ML
Models AO-5000 and AO-10ML use a safety filter in the shaft to help
prevent liquid entering the shaft and contacting the piston, if the plunger
snaps up during aspiration. This is particularly important using large
volumes. If the filter gets wet, replace it.
For AO-5000 insert the small diameter into the shaft, for AO-10ML insert
the large diameter into the shaft. Part number: 30079146 (pack of 100).

Operation

1. Turn the plunger button or the volume adjustment knob until the
volume indicator is 1/3 revolution above the desired setting, then turn
slowly clockwise until the desired volume shows on the indicator.
2. ALWAYS dial down to the desired volume. This prevents mechanical
backlash from affecting accuracy. If you pass the desired setting, turn
the dial 1/3 revolution higher than desired and dial down to reset the
volume. The friction ring prevents unintentional volume changes.
3. Attach a new disposable tip to the pipette shaft. Press into the volume
displayed on the indicator.
4. Holding Across P
the proper depth; see table on page 5.
5 Allow the pushbutton to return slowly to the UP postion. Never let it
snap up! See figure 2A.
6. Pause briefly to ensure that the full volume of sample is drawn into
the tip.
