The mechanical vacuum control provides the vacuum in
the bottle in a range of 150 mbar (minimum switching off
pressure) to 500 mbar (maximum switching on pressure)
for aspiration. At the end of the operation, aspirate all liq
-
uids out of the aspiration tubing and rinse with a cleaning
agent or disinfectant if necessary.
An integrated non-return valve avoids backflow from the
vacuum supply to the BVC basic / BVC basic G. This helps
avoid contamination of the BVC with media that may be
inside the vacuum supply.
When separating the device from the vacuum supply, the
non-return valve avoids venting of the collecting bottle.
The aspiration system doesn’t feature an air admittance
valve. If the collecting bottle is under vacuum, the existing
underpressure inside the bottle remains until the vacuum
is reduced (pressure rises) by further aspiration.
