Retort Sight Tube Cleaning
Retort Sight Tubes should be cleaned weekly to ensure
reagent in Retorts #1 and #2 is filled and maintained at the
appropriate levels for proper processing of tissue speci-
mens, and to guard against reagent overflow.
To clean the Retort Sight Tubes:
1.
Open the Retort Access Door (Figure 7-R). The
Access Door supports will retain the door in the open
position.
Figure 7-R
2. Remove sight tube screw (Figure 7-S)

NOTE: Open Retort #1 and #2 lids manually, as neces-
sary, to facilitate cleaning the retort sight tubes.
3.
Insert the sight tube cleaning brush (see “Section 6,
Consumables and Accessories” for details) into the
sight tube, and scrub up and down several times to
remove debris from the wall of the sight tube (Figure
7-T).

Consumables and Accessories” for details) into the
trap at the bottom of the sight tube. Draw out the re-
maining reagent.

all debris from the sight tube.
