Pl nger Seal Replacement
Ovation M

Replacing a Pl nger Seal:
1. Loosen the two captive screws from
the bottom surface of the pipette
base, using a 5/64’’ Allen Key, until you
can lift the base from the body.
(see Figure 1)
2. Remove the air tube from the rubber
air tube connector cap on the bottom
of the cylinder by gently pulling it from
the circular hole. (see Figure 2)
3. To remove the cylinder, push the
cylinder inwards and rotate it
counterclockwise until the tabs on the
cylinder align with the open slots of the
clear gearbox shell . (see Figure 3)
4.
Remove the plunger seal on the bottom
of the metal plunger by first pushing
down on the plunger button to expose
more of the metal shaft. Then remove
the plunger seal by sliding it off
(see Figure 4). (Note: If the seal remains
stuck to the cylinder top, pop it loose
with a tooth pick or fingernail. Avoid
scratching the plunger with metal tools)
5. Replace the existing plunger seal with
the new plunger seal. Push down on
the plunger button to expose more of
the metal plunger. Then fit the inner
circle of the seal onto the metal
plunger and slide it on until it reaches
the base of the gearbox (see Figure 5)

open slots

6. Gently release the plunger button and
place the new cylinder provided such
that the tabs on the cylinder align with
the open slot in the clear gearbox
(see Figure 3).
7. Push the cylinder inwards and rotate it
clockwise so that the tabs on the
cylinder sit locked atop the inside of
the clear gearbox (see Figure 6).
8. Place the new rubber air tube
connector cap over the small end of
the cylinder and push down so that
the connector cap is seated firmly on
the cylinder (see Figure 7 on back).
9. lide the new O-Ring over the air tube
connector cap so that it sits firmly over
the base of the connector cap
(see Figures 8 and 9 on back).
10. Reinsert the air tube by pushing the
exposed end into the circular opening
on the air tube connector cap (see
Figure 2). (Note: You may need to
rotate the connector cap to allow the
air tube to reach the circular
opening.You will feel two small
“bumps” when pushing the air tube in
to indicate that it has been fully
inserted. You should be able to feel the
back inside wall of the connector cap if
you push any further. )

11. Verify that you have correctly inserted
the air tube into the connector cap by
using the pipette. Confirm that no
leaks occur and that the pipette is
functioning normally.
12. Fit the base to the body so that it fits
neatly onto the front and back cover
and that the screws fit into the holes.
Use the 5/64’’ Allen Key to tighten the
screws until snug and the two halves
are connected. DO NOT over tighten
the screws ( ee Figure 1).
13. Verify pipette performance.
