Go Direct™ Colorimeter

The 4-wavelength Go Direct Colorimeter measures absorbance or transmittance of a liquid sample. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

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 between four wavelengths (430 nm, 470 nm, 565 nm, 635 nm) to set up their experiment.

Go Direct Colorimeter features one-step calibration for all four wavelengths. It’s as simple as inserting a cuvette of distilled water and pressing the Calibrate button.

Go Direct Colorimeter can be used 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.
