Avoid vibration: avoid using vibration equipment (e.g. centrifuge, vortex oscillator, etc.)
inside the cabinet. The contamination might drop from the HEPA filter thus making the operation
area cleanliness lower.

No flame: An open flame would create turbulence which disrupts the pattern of
HEPA-filtered air supplied to the work surface. If sterilization is required during the experiment,
infrared sterilizer is highly recommended.

HEPA filter life: With the usage time increasing, dust and bacteria accumulate within the
HEPA filter, filter resistance is getting bigger, when it reaches the maximum point, the speed
requirements can’t be met then please contact BIOBASE service department to get a new one. The

2.3.2 Operation Process
a. Connect to a suitable power supply
b. Press relevant function keys (related keys, function and operation please refer to 2.2.2 description);
check the function keys and the operation results are consistent, and according to the above
technical parameters table to test whether the blower normal starts and wind speed is up to the
standard requirements, fluorescent lamp and UV lamp is normal work.
UV lamp function could only be selected when front window is fully closed.
c. The cabinet should be sterilized by UV lamp for at least 30 minutes with the window fully closed
before any experiment.
(1) For safety of eyes and skin, people should leave the room during the UV sterilization.
(2) UV lamp should be checked regularly. It should be replaced when either the total working
time reaches 600 hours or the intensity is lower than the requirement.
d. Please move up the front window at the suitable height above the work table and turn on the fan.
Make sure the experiment should be started after fan working for at least 30 minutes.
For operating safety, please place the experiment materials inside the cabinet before
