The ADI
1025 Bio Console
The basic Bio Console is configured to accept 3 fixed speed pumps.
The pump heads that are added to these drives are peristaltic tubing
pumps and are available in various sizes. The Bio Console accepts
up to 4 rotameter flow tubes. The flow range and gas type can be specified
for the application, as required. Each rotameter provides a needle
valve for manual adjustment of gas flow. A separate 3-way valve allows
the operator to select gas flow to the sparger or gas overlay.
A third position allows the gas flow to be shut off. In addition,
solenoid valves are available for each rotameter to control gas flow
as a function of dissolved oxygen or pH setpoint.
As an option the rotameter assemblies can be
replaced with mass flow controllers. The Bio Console can accept up
to 2 mass flow controllers, of various
capacities. The ADI 1010 Bio Controller can control up to 4 mass flow
controllers. Additional mass flow controllers can be mounted in a
gas flow control cabinet. |
The Bio Console also can incorporate a temperature
controller. For temperature control, several options are available. A
thermocirculator can be installed which allows water to flow to the heat
exchanger or jacket of the bioreactor. As an alternative, a heating blanket
or heating element can be plugged into the Bio Console. For cooling purposes,
a cold water solenoid valve can be installed.
All devices described above are controlled from the ADI 1010 Bio Controller
which is installed on top of the Bio Console.
