6.1
General Maintenance
This section provides information on how to care for and
maintain the Tissue-Tek VIP 6 AI. The instrument must be
maintained correctly to ensure proper operation.
Read this section carefully before attempting to perform
maintenance. Follow all instructions carefully.
6.1.1
Daily Maintenance
Retort
WARNING: MAY CONTAIN BIO-HAZARDOUS
WASTE. DISPOSE OF CONTENTS IN
ACCORDANCE WITH LOCAL REGULATIONS.
1.
Clean the inside of the retort lid, the lid gasket, the rim, and
all surfaces and the retort by wiping with a clean cloth. If
xylene is used for any reason, always remove residual
xylene by following up with a cloth moistened with
alcohol. After cleaning, inspect the gasket carefully for
cracks, splitting, tearing, or other signs of deterioration
that could cause leaks. Replace the gasket if necessary.
2.
Clean the outlet filter on the bottom of the retort, as
follows:
Figure 6-A
Grasp the screw and turn counterclockwise, then
remove it from the retort.
a.
Remove any debris, then rinse thoroughly under
running tap water.
b.
Reinstall the filter.
Exterior Surfaces
Keep the exterior of the cabinet free of dust and clutter.
Generally, wiping with a clean cloth moistened with water is
all that is needed to keep the cabinet dust free. Do not use
solvents to clean the exterior, especially the control panel.
To disinfect the touch panel screen, spray 70%-80% alcohol
onto a soft cloth and gently wipe the screen. Do not spray
any liquid directly onto the screen. The acrylic doors may be
cleaned with a glass cleaner and soft cloth.
6.1.2
Weekly Maintenance
Reagent Maintenance
Reagents may be exchanged/rotated manually or by using
the Automatic Transfer (see Section 3). Replace or rotate
processing reagents as determined by laboratory validation.
1.
If manually replacing reagents, empty each bottle, rinse
with compatible reagent and refill with the appropriate
volume of fresh reagent.
2.
If manually rotating reagents, empty the first bottle of
each reagent group, then move remaining reagent(s)
back one to the previous station.
Warm Water Flush-Internal Line Maintenance
1.
The purpose of the Warm Water Flush is to dissolve
chemicals (usually pH buffer salts) in the VIP that
precipitate out of solution when Neutral Buffered
Formalin (NBF) comes into contact with subsequent
alcohols. Precipitation volume depends largely upon the
concentration of alcohol following the NBF. Since the
buffer salts require water to remain in solution, warm
water is placed in the bottles where the precipitate may
accumulate, usually the formalin and first two alcohol
stations. During this “Flush” cycle, the water is drawn
from each bottle to the retort and then returned to the
same bottle.
Exception to Warm Water Flush Maintenance is made when
Tissue-Tek VIP
®
Fixative is used. Because it is a non-
precipitating buffered fixative, the internal line maintenance
is unnecessary.
