Use the Go Direct Colorimeter to explore absorbance and percent transmittance in a variety of experiments including Beer’s law (absorbance vs. concentration) and kinetic studies (concentration vs. time). Select between four wavelengths (430 nm, 470 nm, 565 nm, 635 nm) to set up their experiment. Features one-step calibration for all four wavelengths. It’s as simple as inserting a cuvette of distilled water and pressing the calibrate button. The Go Direct Colorimeter can be used in a variety of experiments such as Beer’s law investigations, determining the concentration of unknown solutions, studying changes in concentration vs. time, and monitoring reaction rates.
Go Direct™ sensors connect directly to your mobile device, Chromebook, or computer using the free Graphical Analysis™ 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth, allowing you to choose the solution best for your classroom or laboratory.
The Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from the free Graphical Analysis™ 4 app. 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.
Range: 0 to 3 (absorbance) Useful ranges: 0.05 to 1.0 (absorbance) and 90% to 10% transmittance (%T) Wavelengths: 430 nm, 470 nm, 565 nm, 635 nm Connections: Bluetooth wireless or USB wired
