7. Connect the jacket cable (Figure 1) to the
corresponding connector of the controller.
It is highly recommended that users routinely
inspect glass vessels for damage, and
replace the vessels if damage is observed.
Disassembling the Glass Bioreactor vessel
1. While supporting the vessel with one hand,
pull up on the agitator motor assembly (Figure
1) to remove. Set the motor assembly aside,
as it
MUST NOT
be washed.
2. Uncouple the jacket cable (Figure 1). Loosen
the hook and loop fastener (Velcro) straps on
the heating jacket (Figure 1) and remove. Set
the heating jacket aside, as it
MUST NOT
be
washed.
3. Remove any septa that are in place, and
replace the septa fitting. Remove all filters and
tubing from the headplate assembly (Figure 2).
4. Unscrew the four headplate retaining screws
(Figure 2).
5. Lift the headplate assembly from the glass
vessel. Some pressure may need to be
applied to release the headplate seal. We
recommend that a second operator support
the vessel stand if this is required. Ensure
that none of the installations of the headplate
assembly (cooling coil, impeller shaft, etc.) hit
the glass rim.
CAUTION: DO NOT USE ANY
SHARP TOOLS
to separate the headplate
assembly from the glass vessel.
6. Remove the glass vessel from the stand.
Store the glass vessel inverted (Figure 3) or on
its side, if adequately supported, to prevent
rolling.
CAUTION:
DO NOT
store the vessel
with the base on the bottom. Because the
base is not flat, the glass vessel can
easily tip over and become damaged.
7. Under the flange of the glass vessel is an
O-ring for centering the headplate’s position
with respect to the glass vessel (Figure 3).
Ensure that the O-ring on the flange around
the glass vessel (as received) is intact when
removing the headplate for cleaning purposes.
8. Depending on the cleaning procedure, the
headplate assembly may be placed in the
stand for washing (Figure 4), but ensure that
all surfaces can be easily cleaned and that the
used cleaning agents drain off.
