CARBON FIBER ELECTRODES

CARBON FIBER ELECTRODES (CFE) are used in conjunction with Pinnacle’s tethered and wireless fast scan cyclic voltammetry (FSCV) system to measure concentration changes of catecholamines and other electroactive analytes. The CFEs can also be used for fixed potential amperometry (FPA). All Pinnacle CFEs require an Ag/AgCl reference electrode. They come in two fiber types - 7 µm (tethered only) and 34 µm (tethered and wireless capable). The 7 µm CFEs are ordered by intended experimental use while the 34 µm CFEs are ordered by cannula type.

Our sensor is a 34 µm diameter carbon fiber housed in a silica sheath that extends 0.5 mm beyond the end of the silica.

CARBON FIBER SENSORS

Carbon fiber sensors are ordered by cannula type and whether the researcher needs to remove them from the cannula for post-calibration. CFS-F sensors are fixed in the cannula and cannot be removed for post-calibration:

Pinnacle offers a variety of biosensor recording systems for both in vivo and in vitro use. Solutions include wireless rat systems for recording up to three biosensors simultaneously. Tethered systems for mice and rats enable monitoring of two biosensors. In addition, we offer bench-top systems that support a range of studies, including brain slices, in vitro, and anesthetized animal experiments.

Pinnacle’s carbon fiber sensors have been optimized for fast scan cyclic voltammetry (FSCV) applications. Our FSCV system is robust, turn-key, and specifically designed to simplify the measurement of catecholamines. Tethered systems for mice and wireless systems for rats are available.
