When using the complete loop fill technique, the syringe capacity should be greater than twice the loop volume. The loop capacity sets the injection volume.
For the partial loop fill technique, the injection volume should be no greater than half the loop capacity. The injection size sets the injection volume.
Note: Users of older Valco injectors requiring 3/4" long needles must fit a Valco VISF-2 adapter.
