Preheating Chambers
Preheating chambers are used to temporarily store
reagent when draining Retorts #1 and #2 prior to transfer-
ring a basket or magazines. The Preheating Chambers
are located between the retorts and the reagent contain-
ers, and keep the reagents warm during basket/magazine
transfers. No user access is required except when
cleaning the Preheating Chamber sight tubes (see
“Preheating Chamber Sight Tube” on page 7.11). Each
preheating chamber has a maximum capacity of approxi-
mately 2.4 liters.
A three-sensor level detection circuit is provided for
reagent level detection.
• The lower-level detector is used to stop supplying
reagent (after supplying approximately 0.6 to 0.8 liter)
when replenishing reagent in Retorts #1 and #2. The
sensor is also used to detect low reagent volume lev-
el for reagent replenishing.
• The mid-level sensor is used to prevent overflow from
the preheating chamber during reagent transfer from
the retort to the preheating chamber. When the mid-
level sensor is actuated, reagent is drained from the
retort to the reagent container rather than being trans-
ferred to the preheating chamber.
• The upper sensor is used to prevent reagent
overflow. The sensor is actuated at approximately 2.5
liters. When the upper sensor is actuated, an audible
alarm sounds, and the line pump is stopped.
A software-controlled temperature regulation unit main-
tains temperature in the preheating chamber.
Reagent Cabinet (Figure 1-H)
Figure 1-H
The reagent cabinet
..25
.. is accessed through a door
in the cabinet front (see “Cabinet Front (Figure 1-A)” on
page 1.3 for details). The reagent cabinet provides
storage space for the reagent containers used by Retorts
#1 and #2. A two-position locking lever
.25a
. associated
with each Retort couples the associated reagent container
with the reagent flow circuit, and secures the container in
place in the cabinet. The reagent cabinet also interfaces
with the Tissue-Tek Xpress x120 fume control system
(see “Fume Control System” on page 1.11 for details).
The reagent containers
.25b
. are disposable containers
that hold the processing reagents for Retorts #1 and #2.
Each reagent container is equipped with a two-piece
cap/connector
.25c
.. 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. The same reagent is used in Retorts
#1 and #2. The caps and labels are color-coded blue so
that the containers cannot be mistaken for other reagents.
