Concentric Electrodes

Microprobes for Life Science offers a variety of popular and fully-customizable concentric electrode designs to meet your research needs. The inner electrode features one of three available metals, and an outer electrode is made of stainless steel. Our CEA Tapered Tip models are precision ground to a pencil point for improve tissue penetration, while our NE Rhodes-Style Tip models feature cylindrical stepped tips to allow for carefully controlled contact surface areas.

The lengths of the different layers of the Rhodes-style electrodes can be customized to provide a great degree of control over probe surface area and impedance.

The CEA-200 tapered concentric electrode is ideal for localized stimulation or population recording in fixed preparations or acute animal experiments. They feature a long, fixed shaft that allows for easy gripping and manipulation, and a sharp durable tip capable of penetrating tough tissue.

Many features are fully customizable by special order, including shaft length, flexible wire length, connector type, and other features. Contact us to learn how our engineers can prepare an electrode ideal for your research.

The NE-100 is designed to replicate the Peter Rhodes-produced NE-100 concentric, and features the same length, thickness, and tip dimensions. These probes feature a stepped tip with well-defined element lengths, allowing surface area to be easily determined for charge density calculations. As in the CEA-200, the NE-100 is ideal for localized stimulation or population recording in fixed preparations for acute animal experiments.

Many features are fully customizable by special order, including shaft length, flexible wire length, connector type, and other features. Contact us to learn how our engineers can prepare an electrode ideal for your research.
