Go Direct® Colorimeter

Go Direct® Colorimeter

Go Direct® Colorimeter

$119.00

The 4-wavelength Go Direct Colorimeter measures absorbance or transmittance of a liquid sample. It connects via Bluetooth® wireless technology or via USB to your device.

ORDER CODE: GDX-COL Categories ,

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.

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 our free Vernier Graphical Analysis™ app, as well as Graphical Analysis Pro and LabQuest® 3. 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.

Wireless or Wired—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our free Graphical Analysis app–no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the solution best for your classroom or laboratory.
