DescriptionModule
A high precision pump which delivers sample or
buffer in purification runs.
Sample pump P9-S or P9H S
Pressure monitor which reads the system pressure
after System Pump A and System Pump B.
Pressure monitor R9
Prevents the system from siphoning when the flow
path after the pump is open. Gives a small back
pressure to the pump in extreme low pressure
applications.
Pump flow restrictor
Mixes the buffers delivered from the system
pumps to a homogeneous buffer composition.
Mixer M9
Three mixer chambers are available for ÄKTA
avant 25. Available volumes are: 0.6 ml, 1.4 ml
(mounted at delivery) and 5 ml.
Three mixer chambers are available for ÄKTA
avant 150. Available volumes are: 1.4 ml, 5 ml
(mounted at delivery), and 15 ml.
CAUTION
Risk of explosion. Do not
use Mixer chamber 15 ml
with an ÄKTA avant 25 sys-
tem configuration. The
maximum pressure for Mix-
er chamber 15 ml is 5 MPa
(50 bar).
Inlet valve for System Pump A with seven inlet
ports and integrated air sensor.
Inlet valve A V9-IA or V9H-IA
Inlet valve for System Pump B with seven inlet
ports and integrated air sensor.
Inlet valve B V9-IB or V9H-IB
Valve which allows automatic mixing of four dif-
ferent solutions.
Quaternary valve Q9
Inlet valve for sample solution, with eight inlet
ports (seven sample inlets and one buffer inlet)
and integrated air sensor.
Sample inlet valve V9-IS or
V9H-IS
Valve which directs sample onto the column.Injection valve V9-Inj or V9H-Inj
