Description

With the Go Direct Cyclic Voltammetry System, developed in part with Pine Research (specialists in electrochemical research instrumentation), students can easily control and apply potential to a chemical system and measure the response as electrical current.

Students can apply analytical techniques, such as cyclic voltammetry or bulk electrolysis, to determine the acetaminophen concentration in medication, to explore antioxidants in everyday beverages, to investigate Faraday’s law, and to understand cyclic voltammetry.

Easily incorporate electrochemistry into your curriculum using our e-book Electrochemistry Experiments with the Go Direct Cyclic Voltammetry System available for free with your purchase.

Rechargeable Battery—Ready When You Are

The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wired or Wireless—The Flexibility to Choose

Go Direct Polarimeter connects directly to your mobile device, Chromebook™, or computer using our free Vernier Instrumental Analysis™ app—no additional equipment or software purchases are necessary. Go Direct sensors connect via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the best solution for your laboratory.
