Easily Read Scales
The numerals on the scales are larger, and therefore more easily read. The scale lines are laser engraved, to allow finest possible permanent marking of scales on all 3 axes. Precise alignment with facing vernier scales gives accurate resolution to 0.1mm.

Smooth Movements
Exclusive, triple lead screws on these manipulators allow the fastest positioning possible, consistent with lining up the scales easily at a given coordinate.

Versatility of Positioning
The manipulator arm controls medio-lateral and vertical positioning via lead screws, and antero-posterior movement via dovetail slide movement, with 80 mm of travel possible in each direction. A Universal Joint allows the investigator to change the angle of the probe up to 90^o in either the antero-posterior or medio-lateral planes. The improved locking mechanism on the Lab Standard™ will hold any angle position without slippage. And of course, it also provides an absolute lock at 90^o vertical.

In addition, a swing joint allows the investigator to conveniently swing the manipulator arm and probe out of the way for performing a procedure – then reliably return the probe to the same point.
