Simultaneously image and photostimulate hundreds of individual cells in 3D, with precise targeting of cells across large areas of the brain. Introducing the HoloStim-3D.
npi electronic VA-10
Designed at the Max-Planck-Institute for Experimental Medicine in Göttingen as an economically priced alternative to do-it-yourself systems and expensive commercial systems.
A sensitive (picoampere range) current amplifier for voltammetric measurements with carbon-fiber microelectrodes in biological systems, where the total currents do not exceed a few tens of nA.
Optional frequency booster for recording very fast signals
Filter settings from 20 Hz to 20 kHz in sixteen steps, 4-pole or 8-pole Bessel filter (1-pole filter on request)
3-electrode headstage for a floating command potential available
Gain settings from 0.5 to 50 mV / pA in seven steps
Precise built-in voltage source for DC amperometry (+/- 1000 mV standard, +/- 2000 mV optional)
Low noise, works in picoampere range
Ideally suited for recordings from single cells
Can be operated with external waveforms for cyclic voltammetry
Telegraph outputs for easy interfacing to data acquisition systems
Allows simultaneous electrophysiological recordings during voltammetric or amperometric investigations using headstages with differential inputs
Can be used in scanning electrochemical microscopy
Also suitable for lipid bilayer recordings
Use with 5 µm carbon fiber electrodes (ALA-CFE-2)
