Carbon microelectrodes for spike recording and microiontophoresis
Our Carbostar series carbon fiber (CF) microelectrodes are made of 7 μm PAN-type graphite monofilament built in borosilicate glass sheathing that provides mechanical support and electrical insulation. They are excel- lent for extracellular potential or spike recordings as well as for electrochemical measurements in vitro or in vivo. These CF microelectrodes are manufactured by a unique dry fabrication method so their storage and shipping over great distances are safe. Iontophoresis barrels are self-filling which make their usage easy with plug and play simplicity. Multibarrel models are always manufactured freshly so allow about a 10-day lead time after placing the order. Their guaranteed shelf life is three months. A female socket mating with the gold- plated pin atop is provided in all shipments. The multibarrel models are also suitable for drug delivery by pres- sure ejection. Standard taper lengths is about 10 mm long. Custom modifications of the standard models are possible for an extra fee. Send in your sketch for a price quote.
These microelectrodes can be conveniently attached to a variety of headstages through our adaptors

Carbostar-1 recording carbon microelectrode
Single barrel carbon fiber electrode for extracellular recording and/or in vivo electro-chemistry. A 7 μm in diameter carbon fiber is galvanically attached to the industry standard pin atop and built in a 1.5 mm diameter borosilicate glass capillary tubing. On the other end, the standard carbon tip is conically shaped and protrudes from the glass insulation by 20 μm +/- 5 μm. This tip is optimized for extracellular recordings. Our ExAmp-20K spike amplifier provides an ultra-low noise recording through its microelectrode carrying headstage probe. Longer carbon tips may be required in electrochemical measurements or use our CFE- or CDE-series carbon microelectrode models. Please contact us for custom modifications if needed.
