Plunger Wire Replacement
3M0828
Reference: Use this instruction with replace-
ment part 3M0828 (2 per pack-
age). Replace the sampler
plunger wire with each new
test kit (500 samples).
See your instrument User’s Guide for detailed
operating instructions and illustrations.
Instruction:
Replace the plunger wire on the sampler
every 500 tests (each package of sampler
tips):
1. Unscrew the calibration gauge and key
(A). Rotate the shaft (B) until the calibra-
tion setscrew appears beneath the access
hole (C) in the side of the sampler body.
Use the calibration key to loosen the
setscrew.
2. Carefully remove the old sampler plunger
wire. If it contains a plastic sleeve, save
and install it on the new plunger.
3. Slip a new sampler plunger wire into a
new sampler tip so the teflon plunger tip
protrudes about 1/16" or 1.6 mm (D).
4. Insert the plunger wire into the sampler
body and secure the sampler tip onto it.
5. Using the calibration gauge and key, push
the plunger into the sampler as far as it
will go (E).
6. Tighten the calibration setscrew with the
calibration gauge.
7. Screw the calibration gauge and key back
into the top of the sampler.
8. Your 20 µL Sampler is now calibrated
and ready to use.
(For calibration only, simply follow steps 1, 5,
6 and 7.)
