Using Squidstats for Stack Measurements on Batteries or Fuel Cells

This application note introduces the differences between using a serial connection versus a parallel connection when using Squidstats to measure interconnected electrochemical systems.

Using Squidstats To Perform Corrosion Testing On a Metal Coupon

Any Squidstat potentiostat can be a very useful tool for quality control testing and to evaluate new material formulations for corrosion protection.

Application Notes & How-To Guides

Introduction to Electrochemical Impedance Spectroscopy (EIS)

EIS is a popular, powerful measurement method that can be used for anything from routine testing to cutting edge R&D of next-generation electrochemical systems.

Calculating Corrosion Rates From a Tafel Plot

Creating and analyzing a Tafel plot is a powerful and time-tested electrochemical testing method to obtain corrosion data and understand corrosion behaviors.

SLIDESHOW - EIS for Advanced Battery Diagnostics

This 16-slide presentation covers key concepts about running EIS on batteries, analyzing the resulting data, and explaining the differences between EIS and traditional DC measurements.

Running RRDE Experiments with Squidstat Potentiostats

RRDE is commonly used to study many types of convective electrochemical systems. This application note explains how to successfully carry out RRDE measurements with Squidstat potentiostats.

Carrying Out Simultaneous EIS Measurements on Multiple High Current Battery Stacks

This application note is for customers working with multiple high current battery stacks in the range of 400 Ah which require the use of high-current load banks, and parallel EIS measurements using the PAD4 add-on to the Zennium.

IR Drop Compensation with Squidstat Potentiostats

Understanding and correcting the IR drop that occurs to uncompensated ohmic resistance reduces errors in electrochemical measurements.

Understanding and Validating Potentiostat DC Accuracy

This guide explains the fundamental aspects of defining measurement accuracy, and provides a step-by-step list of instructions for validating the DC accuracy of any potentiostat (not just Squidstats!)

SLIDESHOW - Introduction to Potentiostat Design & Engineering

Anyone who has ever wondered about the electrical engineering aspects of potentiostat design & functionality would be well-served to review this 25-slide presentation.

Using Cyclic Voltammetry To Study Redox Reactions

Cyclic Voltammetry is the defining test method potentiostats are designed to perform. There are several key considerations to understand when running CVs on samples.

Accuracy Contour Plots and EIS Accuracy

EIS performance of an instrument is most often communicated through a figure know as an Accuracy Contour Plot. This application note explains how to interpret such figures properly, and to understand what is most important to look for. 

SLIDESHOW - Squidstat Setup Guide To Run As A Bipotentiostat for RRDE Experiments

This is a step-by-step guide covering how to setup two Squidstat potentiostats in a bipotentiostat configuration to run RRDE experiments in the Squidstat User Interface software.

  • How often should we consider recalibrating our Squidstats, if ever?
    Recalibration should not be needed within the 2-year warranty period (assuming no hardware damage). After the warranty period expires, we offer recalibration services to those who want it and can provide it on an annual basis - but this is by no means required and we expect the calibration to stay within specifications without having to perform a recalibration. Our application note titled Understanding and Validating Potentiostat DC Accuracy explains how to run your own measurements to validate the accuracy of your Squidstat channels. In the absence of high precision multimeter equipment that you likely don’t have in your new lab, we recommend high-precision resistors.
  • What are the minimum computer specifications recommended to run the Squidstat software?
    Our Squidstat software is natively compatible with 64-bit computers running Windows 7 & above, MacOS 10.14 & above, and Ubuntu 18.04 & above. Any users using 32-bit computers must request a special software version to download. We recommend only using computers with at least 8 GB of RAM installed. There are no specific requirements for processor speed. Our software is optimized to display on a screen with a 16:9 aspect ratio, but will resize to fit onto practically any screen.
  • What are Admiral Instruments' warranty and refund terms?
    All customers have a 30 day window after delivery of their Squidstat to return it for a full refund. During this 30 day period, customers may ask to return products for a refund for any reason. After 30 days, customers are covered by our 2-year warranty for repairs or replacements but will no longer be eligible for refunds. Our Limited Warranty covers any defects in material or workmanship under normal use during the two year period following delivery of products. During this period, Admiral Instruments will repair or replace, at no charge, products or parts of a product that proves defective because of improper material or workmanship, under normal use and maintenance. However, cables and cable clips are excluded from these warranty terms due to the unpredictable conditions some customers may subject them to during the course of their experiments. Replacement cables are available for purchase. All products originating from Zahner are covered by our 2-year Limited Warranty terms described above. However, none of the Zahner products are covered by the 30-day money back guarantee due to the terms of our distribution arrangements.
  • What electrical certification markings do your Squidstats conform to (UL, CE, CSA, etc.)?"
    All Squidstats conform to the CE directives for low voltage electrical devices. We have the ability to have a CSA certification applied to any individual Squidstat through the CSA Field Inspection process. If your lab requires equipment to conform to additional standards beyond CE or CSA please contact us.
  • Why does Admiral Instruments openly show pricing information about the Squidstat potentiostats? And are discounts available?
    One of our top-5 core values as a company is Transparency. Our company culture is built around this ideal, and one of the ways we act on this ideal is to publicly list pricing for our Squidstats. We publicly list our pricing online and make a serious effort to offer everyone excellent value upfront, no matter if they are a budget-conscious academic research lab or a richly-funded industry lab. Customers understand that our approach helps them save their valuable time negotiating lower prices on single-unit purchases. With that said, we can offer discounts on multi-unit Squidstat purchases because we save time and money whenever building larger orders (typically valued above $20,000), and pass those savings to our customers. However, for single-unit purchases our pricing is already as low as possible – even for academic customers. Our Squidstats are designed to be the best priced research-grade potentiostats in the market but if you find a competitor offering better value for your money please let us know!
  • What type of USB connection standard do the Squidstats use? Is is okay to use a USB hub?
    All of our Squidstats use a USB 2.0 connection. We supply an approximately 2 meter long USB cable with all Squidstat shipments, but users can opt to use their own USB cables up to 5 meters in length. The USB 2.0 connection standard does not officially support USB cables longer than 5 meters. If you need to use a USB hub, we recommend using a hub that has an external power connection.
  • How is raw data collected by the Squidstats formatted, and can it be exported into data analysis programs?
    All Squidstats have raw data saved into a .csv file that can be easily exported into other programs for more advanced analysis. Our advantage over most other potentiostats is that all data collected while any Squidstat channel is running is continuously recorded and automatically saved into the .csv file. Users are not required to save their data any time after a channel has started running. This means that in the event of a loss of power to the Squidstat or a similar issue, the data collected during the experiment can be retrieved up to the point of power loss. ​Better yet, if there is a computer crash or loss of power, but power is still available on the Squidstat, the experiment that was already running at the time of computer failure will still continue uninterrupted on the Squidstat.
