VersaSTAT MC Overview
The VersaSTAT MC is our multi-channel potentiostat/galvanostat/impedance analyzer, combining fifty years of Princeton Applied Research knowledge and expertise in the development of world leading electrochemical test products with advanced performance from the very latest measurement technology. This, together with easy to use, yet powerful PC software makes the VersaSTAT MC an impressive combination of value, performance, and productivity.
Princeton Applied Research recognizes that traditional single channel systems do not always satisfy the demands for economy and throughput, yet many multi-channel systems are designed to satisfy only specific markets and/or applications. The VersaSTAT MC was designed to have the broad capabilities of a research-grade single-channel electrochemical system along with the value and increased throughput provided by multi-channel systems.
Each VersaSTAT MC can be equipped with up to four (4) channels. The system can be ordered fully loaded, or for those with limited budgets, the VersaSTAT MC can be purchased initially with only a single channel then upgraded later to add additional channels or options as needed or budget permits. If more than four channels are needed, multiple units can interface the same computer and all channels controlled indepentely with the VersaStudio software.
- Versatile performance in choice of 1-4 channels
- ±650mA / ±10V polarization range as standard
- Impedance measurement capability standard on all channels for simultaneous and/or independent operation from 10µHz to 1MHz with no separate analyzer required
- Options for each channel include ±2A high current option and boosters up to 20A
- High speed DC measurement and experiment sequencing (e.g. for step/pulse analysis)
- VersaStudio software designed for versatility and ease of use

Great post. I am facing a couple of these problems.
Thank you for the auspicious writeup. It in fact was a amusement account it. Look advanced to more added agreeable from you! However, how could we communicate?
I was looking at some of your posts on this website and I believe this internet site is very informative ! Retain putting up.
Today, I went to the beach front with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is completely off topic but I had to tell someone!
You have brought up a very excellent points, thankyou for the post.
Heya i am for the first time here. I found this board and I find It really useful & it helped me out a lot. I hope to give something back and help others like you helped me.
