CARE OF THE INSTRUMENT
7.4 Revised 10/02/2012
Reagent Replacement
Reagent must be replaced periodically (after a speci-
fied number of runs or cassettes have been processed, or
in the event an insufficient amount of reagent is available
for processing) to ensure proper processing of tissue
specimens. The instrument can be configured to count the
number of cassettes processed, or the number of runs
processed, as an aid in determining when to replace the
reagents (see “
Configuring System Settings ” on page 3.2
for details). The “run” or “cassette” count is shown in the
lower window of the WARMING UP SYSTEM, MANUAL
START and AUTO START screens.
NOTE: Depending on the types of tissues processed and
the hours of operation, the four-retort reagents set should
be replaced after processing up to 1,500 specimens, up
to about every 37 runs, or up to every 3 days, whichever
comes first.
Following reagent replacement, the reagent counter
status must be cleared to ensure proper tracking of the
number of processed runs for the fresh reagents (see
“Clearing the Reagent Counter” on page 7.7 for details).
CAUTION: To ensure proper processing of tissue
specimens, reagent for Retorts #1 and #2, and paraffin
for Retorts #3 and #4 MUST be replaced at the same
time.
NOTE: Refer to
“Section 9, Service and Replacement
Parts” , for information on obtaining replacement reagents.
Retorts #1 and #2 Reagent Replacement
NOTE: Each reagent container is equipped with a two-
piece cap/connector. The upper cap is used during
shipment and storage of the container. The lower cap
facilitates connection of the container to the Tissue-Tek
Xpress x120 system.
WARNING: THE REAGENT CONTAINERS MAY
CONTAIN BIOHAZARDOUS WASTE. DISPOSE OF
CONTENTS IN ACCORDANCE WITH LOCAL
REGULATIONS.
To replace Retorts #1 and #2 reagents:
1.
Perform a system shutdown.
2. Open Retort #1/#2 Reagent Cabinet Access Door
(Figure 7-C).
Figure 7-C
NOTE: The instrument utilizes a
two-position locking lever to couple
the reagent containers to the rea-
gent supply system for Retorts #1
and #2.
3. Press each reagent container
locking lever down to the “RELEASE” (lower) position,
then allow the lever to return to the “UNLOCKED”
(upper) position, uncoupling the reagent containers
(Figure 7-D).

4. Remove the reagent containers from the reagent
cabinet.
5. Invert the new reagent bottles 4-5 times to gently mix
the solution, prior to placing on the instrument.
