What is a potentiostat and how to connect a potentiostat?

In this video we'll be talking about what a potentiostat, galvanostat and a frequency analyzer are, why you would use them, and how to connect the electrodes. You can see examples of classic and screen-printed electrodes and four different types of electrochemical techniques.
A potentiostat is a lab instrument that is used for measuring the current while applying a voltage. By understanding how a potentiostat works, you will be able to use it more effectively in your lab experiments. This video is designed to give you a basic understanding of the instrument, how to connect your electrodes and what electrochemical techniques exist.

You are a great teacher! Thank you for the informative video 🙂

[@PalmSens]

Thanks for watching!

[@tommybrown3095]

Great one there I want to get the Device in my laboratory.

[@PalmSens]

Great that you like it. Just visit our website www.palmsens.com/ and pick one you like.

Can Palm sense BT determine charge discharge??

[@PalmSens]

Usually charge-discharge measurements are performed galvanostatic, i.e. a current is applied. The Sensit models don't offer galvanostatic control, thus we don't recommend the Sensit BT for charge-discharge measurements.

Thank you for this interesting video, I would like to know if the screen-printed electrode is considered as a battery ? Meaning can I chose the material I want to work with for the working or the counter electrode ? and how is the electrolyte added ?

[@PalmSens]

A Screen-Printed electrode is not a battery.
Yes, you can choose the material you would like to work with. Different producers offer different materials. A selection can be found in our catalog: www.palmsens.com/products/sensors/screen-printed-electrodes/
The electrodes can be immersed in the electrodes or a drop of electrolyte is applied to the electrode. You can find multiple demonstrations on our RUclips channel, for example ruclips.net/video/5-rk_Uab1hE/видео.html
