Use this sensor to measure absorbance and transmittance in a variety of experiments including Beer's law (absorbance vs. concentration) and kinetic studies (concentration vs. time). Students select from 4 wavelengths (430 nm, 470 nm, 565 nm, 635 nm) to set up their experiment. The colorimeter's calibration is simple—insert a cuvette of distilled water and press the Calibrate button. Rechargeable battery offers long battery life. Includes plastic cuvettes and micro USB cable.

Tariffs have driven up the cost of this item significantly. We apologize for the price increase. We are absorbing some of the impact to help teachers but are forced to pass most of it along.

Product Details
Use this sensor to explore absorbance and percent transmittance in a variety of experiments including Beer's law (absorbance vs. concentration) and kinetic studies (concentration vs. time). Students select from 4 wavelengths (430 nm, 470 nm, 565 nm, 635 nm) to set up their experiment. Go Direct® Colorimeter features one-step calibration for all 4 wavelengths. It's as simple as inserting a cuvette of distilled water and pressing the Calibrate button.

Use the Go Direct® Colorimeter in a variety of experiments:

• Conduct Beer's law investigations
• Determine the concentration of unknown solutions
• Study changes in concentration vs. time
• Monitor reaction rates

Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from the award-winning Vernier Graphical Analysis® Pro app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the included charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose
The Go Direct® sensor connects directly to your mobile device and Chromebook™ or other computer using the Vernier Graphical Analysis® Pro app—no additional equipment or software purchases are necessary. The sensor also can be used wired via USB or wirelessly via Bluetooth® technology, allowing you to choose the solution best for your classroom or laboratory.
