Reed Contact
The reed contact inside the 2-position valve causes a short-circuit contact. This
short-circuit contact can be used as a start signal for the entire analytical system
or as a start signal for a measurement with the detector. The function is to be
set on the receiving device.
Multiposition Valves
Multiposition valves are used to switch fluid streams, e.g. the selection of elu-
ents, columns or for fractionating of eluate. Multiposition valves are employed
for fractioning if the form and the size of the fraction containers should be freely
selectable. By combining up to 8 multiposition valves, up to 120 positions can
be used for fractioning in applications in the preparative HPLC.
You control all multiposition valves electrically through a valve drive. 6P-multi-
position valves can alternatively be controlled manually through a lever.
