The Thomas RECORDING stereotaxic instrument for non-human primates called PPS (Precision Positioning System) was originally designed 30 years ago in the research lab of Prof. Dr. Dr. Heribert Reitboeck and Prof. Dr. Reinhard Eckhorn at the Neurophysics Department, University of Marburg, Germany.

The product consists of a rigid table, a primate chair with trolley, a stable frame made of strong aluminum profiles with a curved guided rail, holding the instruments like a xyz manipulator for a Thomas Microdrive system and a reward unit. Furthermore the PPS is equipped with a unique three point head holding system.

The PPS has many degrees of freedom like shown in figure 2.

Based on the fact that this instrument is engineered and manufactured in Germany a high product quality and reliability is guaranteed. 

The product is modular so that we can customize each component for an easy integration of the system in the customer′s lab environment.
