Go Direct® Polarimeter |

Go Direct® Polarimeter is available April 2020

The concept of chirality can be difficult for students to visualise. Go Direct Polarimeter provides a visual representation of this concept by measuring the optical rotation of optical isomers such as sugars, amino acids, and proteins. The Go Direct Polarimeter is simple to use, includes free, downloadable experiments, and is supported by the free Vernier Instrumental Analysis™ app.

Description

Its unique vertical layout and lack of custom glassware make this polarimeter very student friendly. In addition, the analyser is automatically rotated by an internal motor giving students more time to understand experiments such as the reaction kinetics of HCl and sucrose. The 589 nm LED makes it ideal for comparing optical rotation values to those in literature, allowing students to calculate specific rotation for sucrose, fructose, and other optically active samples. Students no longer have to determine the optical maximum with their eye—they now have a graph that shows a clear change in the light’s polarisation.

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.
