Manual Injector

Manual Injector

The Agilent 1220 Infinity II LC manual injector uses a Rheodyne, 6-port
sample injection valve (5067-4202). Sample is loaded into the external 20 μL
sample loop through the injection port at the front of the valve. The valve has a
PEEK™ injection seal. A make-before-break passage in the stator ensures flow
is not interrupted when the valve is switched between the INJECT and LOAD
positions, and back again.
