3. Loosen the three captive screws on the
underside of the pipette using the provided
5/64’’ Allen Key. Remove the Cylinder
Assembly to expose the bottom end of
the air tube. (see Figures 3 & 4)
4. Remove the white Ejector Sleeve from
the pipette by firmly pulling it outward.
(see Figure 5)
5. Remove the Nozzle by unscrewing it
counterclockwise from the extension
tube. You can slide the provided silicone
sleeve over the nozzle for better grip
and leverage. (see Figure 6)
6. Attach the Air Tube Cleaner Nozzle by
screwing the threaded end of the nozzle
onto the nozzle extension tube with the
aid of the same silicone sleeve if
needed. (see Figure 7)
Tighten until the nozzle sits flush with
the extension tube. Remove the silicone
sleeve when finished.
Wear Safety Glasses when
performing the next steps.
7. Aspirate approximately 1 mL of warm
water into the provided syringe. Attach
the syringe to the Air Tube Cleaner
Nozzle by inserting the syringe into the
open end of the nozzle and pushing
firmly to seal. (see Figure 8).
8.
With the open end of the air tube over
a liquid receptacle or a sink and the
Base held out of the way, slowly
force the warm water into the pipette.
It may take up to a minute of firm
pressure to clear out the blockage in
the Air Tube. (see Figure 9)
9. When the syringe is empty, pump the
syringe plunger all the way out and then
all the way in about 10 times to remove
any residual liquid. (see Figure 10)
10. Detach the syringe, fill syringe with the
cleaning solution, and re-attach it.
With the open end of the air tube over
a liquid receptacle or a sink and the
Base held out of the way, slowly
force the cleaning solution into the
pipette.
When the syringe is empty, pump the
syringe plunger all the way out and then
all the way in about 10 times to remove
any residual liquid. (see Figure 10)
Allow the unit to air dry for 30 minutes
before re-assembly
