Valve Upgrade for EASY nLC Systems

  • Easy way to upgrade your nLC system
  • New stator design removes the possibility of causing damage by overtightening fittings designed to make a seal on the tube face
  • Buy a complete valve or upgrade the stator on your existing valve

Fittings which effect a seal at the tubing face can apply enough force against the bottom of a 1/16" ZDV detail to cause distortion of the stator surface. (See profilometer images below.) The distortion may only be a few 10,000ths of an inch, but it's enough to create a tiny leak which can be problematic when flow rates are in the nanoliters-per-minute range. This new stator design virtually eliminates the problem.

Our new fitting connects a 360 µm FS tube directly into a 1/16" fitting detail, with the bore of the FS tube precisely aligning with the bore of the valve. Product information


Premature valve failure can also be caused by following the instrument manufacturers' instructions to put the valve in mid-position for a leak check. If you experience this problem, contact us for a special rotor with a dimple mid-position, which allows this test to be performed without damaging the valve.
