Essential Potentiostats

SP-50e Potentiostat.

A cost-effective potentiostat with advanced functionality, ideal for Education

A robust, single channel, general purpose potentiostat perfect for both general electrochemistry research needs as well as teaching.

A robust, single-channel, general-purpose electrochemical workstation, the SP-50e is perfectly suited to both general electrochemistry research needs as well as education and is highly suitable for teaching undergraduate electrochemistry.


While some low-cost potentiostats are limited in their scope, the BioLogic SP-50e, which exploits the same high-quality hardware and software as other instruments in the Essential product range, offers both ease of use and the potential to work on a vast array of techniques and applications, including EIS as an option, whilst still offering excellent value for money. Furthermore, high-quality hardware and software platforms mean no programming skill is required to operate the instrument.


The SP-50e potentiostat combined with EC-Lab® control and analysis software provides a full, integrated solution for students to study a variety of electrochemical reactions and systems. With its reduced footprint, lightweight (3.9 kg), and carrying handle, students and instructors can easily transport the potentiostat around the laboratory.


This research-grade potentiostat is suitable for performing experiments such as Cyclic Voltammetry, ChronoAmperometry, and Linear Sweep Voltammetry for Rotating-Disk-Electrode, as well as all the 80+ techniques available in EC-Lab software.


A ±1 ampere capable range makes the SP-50e perfect for energy-based applications including battery, supercapacitor, fuel cell, and electrolysis research.


Powered by BioLogic EC-Lab software, widely recognized by leading scientists as the benchmark control and analysis software for potentiostat / galvanostats, users are able to exploit a wide range of functions covering not just potentiostat control, but electrochemical analysis as well.


There is no need to split tasks across different software applications. Everything can be found in one place – simplifying your professional life, and saving you precious research time.


All this, in a compact potentiostat with a reduced laboratory footprint, opening up space on the laboratory bench

BioLogic EC-Lab software – Benchmark potentiostat control and analysis software

Powerful, modular, and easy to use
The most powerful hardware is only as performant as the software that sits behind it. EC-Lab has earned itself the reputation as the benchmark for potentiostat control software, based on a combination of intuitive control and analytic power.
