Question
What is the resolution of the burette motor used for volume additions on the AT1000/KF1000 titrators?
Summary
AT1000/KF1000 syringe accuracy.
Answer
The resolution of volume addition is dependent on which syringe is used with the titrator.

The stepper motor that drives the syringe plunger has a resolution of 20,000 steps with microstepping technology (128 microsteps/step).

However the actual volume addition resolution used during a titration varies when using dynamic volume addition or is determined by the increment when using a monotonic volume addition. The accuracy of the volume graduations on the side of the syringes is irrelevant.
