Newnanovolume® injectors featureauniformflowpathas small as100microns,
with speciallydesignedfittings for 1/32"or 360micronPEEK, fused silica,orValco
electroformednickel tubing. Modelsare rated from5,000 to20,000psi,with
mosthavingaproprietarycoated stainless stator andhigh-strengthPAEK rotor
toensure longperiodsofmaintenance-freeoperation.

TheVICI 40K injector is comprisedof sixminiatureair actuatedneedlevalves,
plumbed to simulate theflowpathof aconventional rotor/stator injector.
An integral controller sends theon/offpositioning signals toeachvalve,
coordinating them toperform load, inject,andflush functions.
