Shielded reference electrode for sensitive measurements

Ag/AgCl reference electrode in stainless steel shield

We encapsulated Ag/AgCl reference electrode in stainless steel shield. Now it can be easily grounded. Therefore even with the longest reference electrodes (we manufacture electrodes up to 20 cm in length), the level of noise will be reduced. The shield can be also used as an auxiliary electrode.

Through wall reference electrode for neurophysiology

This Ag/AgCl references electrode can be installed through the wall or bottom of the experimental chamber (e.g. for slice electrophysiology) saving space above the chamber for multiple microelectrodes and their holders and decreasing wiring mess and noise.

Add In Vivo Voltammetry to your existing neurophysiological setup (Axon Instrument or similar)

Switch box for adding in vivo voltammetry to the existing neurophysiological setup
The head stage permits fast cyclic voltammetry and electrophysiology from the same 1-30 um diameter microelectrode almost simultaneously. With this addition real-time measurements of dopamine, noradrenaline, serotonin, pH shifts, H2O2, adenosine and oxygen concentrations can be made.

Fast-scan controlled adsorption voltammetry (FSCAV)

Fast-scan controlled adsorption voltammetry (FSCAV), which has been described in a few recent publications, requires complicated and expensive hardware as well as its own software.
Invilog now provides an application which exploits this promising method and we are offering equipment which incorporates FSCAV as a novel component of its measurement possibilities – and at the price of our basic setup.

New three electrode head stage for CPA

Three electrode head stage is a fully equipped potentiostat enable to measure 1 ms, 10nM peaks of dopamine or other neurochemicals.
With this new design, 2 nA/V sensitivity for dopamine or noradrenaline can be achieved without significant signal distortion even at 5KHz frequency. In terms of  concentrations it means that at the Invilog carbon fiber 32 micron electrodes, we can now obtain as short as 1 ms in length, 10 nM peaks.

Invilog balanced multi-axis lever for in vivo voltammetry, electrophysiology or microdialysis

Unique constant force adjustable spring system balances attachment in any working position so that the pulling force via the cable or catheter is always the same.

Optostimulating electrodes for peripheral nerves stimulation

Ready for chronic implantation three types of LED based optostimulating electrodes designed for stimulation of the peripheral nerves in mice or rats. Manufactured with 470 nm (blue) superbright LEDs (30 mA max current), but can be customized in color, size and power.

Replaceable reference electrodes for chronic brain implantation

Reference electrodes change their properties after chronic  implantation in the brain.

Invilog addresses the problem by offering chronically implanted electrode with always fresh replaceable Ag/AgCl element.
