The VA-10X is a sensitive (picoampere range) current amplifier that is intended for voltammetric measurements. It can be used with carbon-fiber microelectrodes in biological systems, where the total currents do not exceed a few tens of nA, or with other electrode types. The current range can be customised with different feedback resistors, also a switchable headstage is available for higher flexibility during experiments.
Besides the current range, also filter frequencies, gain stages or headstages can be customised. If you require a special design, please let us know.
It was 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.
It can be used for either DC amperometry using the built-in voltage source, or it can be operated with user-supplied external voltage waveforms (e.g. for cyclic voltammetry).
The VA-10X-8 is equipped with high performance 8-pole Bessel filters.
The device can be widely customised Ask npi electronic for headstages with different feedback resistors, multi electrode headstages, or miniaturised headstages for in-vivo recordings.
Optionally, the VA-10X can be equipped with a frequency booster in order to enhance the recording bandwidth to several kHz.
The device can be adapted to directly replace the discontinued Dagan Chem-Clamp.
The VA-10 is also available as module for the EPMS-07 system.
