Valve Upgrade for Nano LC Systems

Easy way to upgrade your Easy-nLC system

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.

  • Easy way to upgrade your Easy-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

Tech Tip

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.
