Follow the instructions as directed on the

To lubricate the O-rings, first use a twisted Kimwipe or lens cloth to “floss” between the nozzles
and remove any grease from the white tip ejector block above the nozzles. If necessary, pull the
tip ejector block down to thoroughly clean the end of it.
Next, take a
very small
amount of silicone grease (1/3 of a grain of rice) and rub between gloved
thumb and forefinger to yield a sheen of grease. Then, apply greased thumb and forefinger to
the nozzle around the O-ring as shown (Figure 122).
After applying grease to the
front
and
back
of
each nozzle, stick a pipette tip on the nozzle
and twist it lightly back and forth, to spread
the grease to the
sides
of the nozzles.
IMPORTANT:
Do not use anything other
than the supplied silicone grease on O-
rings.
IMPORTANT:
Excessive grease may cause
equipment malfunction. To test before
running samples, perform the
described in the next section.

screen.

of NanoString silicone grease to the O-rings.
