How Much Does a Potentiostat Cost? (And Why That's the Wrong First Question)

A potentiostat can cost from about $50 to over $20,000, but price is the wrong place to start. What really sets the cost is what you need to measure. Here is how it works, tier by tier, and how to pay for fit, not features.
