3 Description of modules
3.2 Inlet valves
Function
The inlet valve modules consist of a number of membrane valves. The first A inlet port,
A1, is used for buffer solution. A2 and A3 are used for sample or buffer solutions. If more
A inlets are required, up to three inlet valve modules can be installed which results in
nine A inlets.
The B inlets are used for buffer and wash solutions. If more B inlets are required, another
B inlet module can be installed which results in six B inlets.
Note:
Inlet tubing
Tubing with inner diameter 4.8 mm and SNAP 4.8 connectors is used on the valve inlets.
An adapter can be used between the SNAP 4.8 connector and the larger TC25 clamp to
use tubing with larger diameter. Tubing with larger diameter is needed in the following
cases:

When running isocratic dual pump flow, make sure that the same buffer solu-
tion is pumped in pump A and pump B. For example, place the A and B inlets
in the same buffer container. See
