G23 Instruments produces microelectrode holders and other high quality scientific equipment, primarily for the electrophysiologist. The company works closely with active research staff within the Research Department of Neuroscience, Physiology & Pharmacology at University College London and its novel equipment and designs are thoroughly tested under rigorous research conditions.

We market microelectrode holders for Axon Instruments headstages and HEKA patch clamp amplifiers, and accessories. Our microelectrode holders have been recommended by both Axon and Burleigh Instruments (Dec 2010) for long term recording and stability and are used by some of the best electrophysiological laboratories in the world.

In September 2009 we introduced new versions of our electrode holders. These include the new ISO range and a new H-series rigid adapter allowing any electrode holder to be used with head stages that require a BNC input (e.g. the HEKA headstages) without using a soldered connection.

All our holders have gold-plated pins for better connectivity.

See Choosing a holder for advice on which holder to purchase.
