The founder of npi, Hans Reiner Polder, developed a new compensating method for intracellular amplifiers during his diploma thesis (TU Munich, c/o MPI for Psychiatry). This was used together with control theory approaches to increase the measuring range. 35 year ago, this was the basis of a new generation of amplifiers and the beginning of npi electronic.

Our amplifiers cover all standard applications (EEG, LFP, PatchClamp, etc.) as well as specialized instruments for sophisticated applications. npi’s strength is the special control and design of our intracellular amplifiers for recording also from the most demanding cells. Our substance application systems (pneumatic or iontophoretic) have been further developed to allow extraordinarily fast and spatially precise applications. Devices for optical stimulation (optogenetics) and fiber based Ca2+-fluorescence recording complete our product range.

We design and produce our instruments in Tamm, Germany. In-house production and development allows us to regularly customize our standard products to fit the scientists’ requirements every time. We develop new recording methods and build prototypes in collaboration with the involved scientists.

npi and teaching: we support practical courses with our knowledge and instruments. We also build special devices for teaching labs.

We design and install complete recording setups, including all required periphery. 35 years of experience made us a benchmark in this field. Our service includes on-site installation, training for users and long term support.
