1 Introduction
Valve INV-907 is a motorised rotary 7–port
valve. The valve is used in ÄKTA
™
design
chromatography systems. It is powered from
the ÄKTAdesign P-900 series system pump, and
is controlled from UNICORN
™
control system.
The valve has 3 positions used for:
- loading a sample loop
- injecting the sample onto the column
- washing the system pump.
The valve can also be used to switch between
upflow and downflow in a column.
Features:
•
Completely swept flow path minimises
eluent or sample ”memory effect”.
•
Flow rates up to 100 ml/min.

All wetted parts are plastic PEEK.
Safety
2 Installation
Unpacking
Unpack the valve and check the items against
the packing list. Inspect the items for obvious
damage which may have occurred during
transportation.
Installing the valve
1 Connect the valve with
two UniNet cables as a
part of the UniNet 2
chain.
2 Set the ID-switch at the
bottom to
the required valve number
0–9
. The
number should correspond to that used in
UNICORN.
Note: All valves must have different
numbers.
3 Mount the valve vertically, in the way it
is shown in the user documentation of
your ÄKTAdesign chromatography
system.
4 Apply an identification number from the
labels supplied. The number should be the
same as that of the rotary switch at the
bottom of the valve. Place the number so
that it is easily readable from the front.
5 Connect the tubing.
CAUTION! Before connecting Valve
INV-907 ensure the power is switched OFF
at the system pump or the complete system.
WARNING! When using hazardous
chemicals, all suitable protective measures,
such as protective glasses, must be taken.
