2. Attach a strainer to the suction line (Section
3. Connect the suction line to the pump tube
(Section 1.8.2).
Note
The vinyl suction line does contain a very low ppm
(parts per million) level of phenols. If this affects your
samples, use the Teflon suction line.
1.8.1 Cutting the Suction Line
The suction line should be cut to the shortest
feasible length. This reduces the possibility of
cross-contamination between sample volumes
and extends the battery life. The suction line
can be easily cut with a knife.
When cutting the suction line, keep in mind the
length must be cut to the nearest whole foot or
decimeter. The length is measured from end to
end, without the strainer or tubing coupler.
If you have altered the length, press the
Calibrate button, and enter the new suction
line dimensions.
1.8.2 Attaching the Strainer
Items required:
Strainer
Suction line
To attach the strainer to the suction line:
1. Heat the end of the suction line to make it
more pliable.
2. Screw the threaded end of the strainer into
the suction line.
