Rinse Station and Drain Waste
Tubing Installation
You’ll clean the probe using the rinse station. To
eliminate carryover of liquids, the rinsing procedure
pumps an excess volume of diluent or probe
washing solution through the probe and out into
the rinse station. The small diameter of the rinse
station inserts allow the outside of the probe to be
washed along with the inside.
The rinse station’s design accommodates three
kinds of rinses:
• Shallow-pocket rinse - Used
for level sensing applications
where the probe is only
immersed in a few
millimeters of the sample.
• Deep-pocket rinse - Used
for non-level sensing
applications. This type of
insert allows for a deeper
insertion of the probe into
the rinse well resulting in a
greater area of the outside
of the probe to be rinsed.
• Flow-through rinse - Used
in applications where a
rigorous wash of the
probe’s exterior is required.
A second source of liquid is pumped to the
rinse station to perform this type of rinse.
It may be necessary to vary the types and
volumes of probe wash solutions to most
efficiently eliminate carryover of particular
compounds. Generally, the smaller the volume
of probe wash solution used, the faster your
automated liquid handling protocol.
