VERNIER GO DIRECT COLORIMETER
Vernier's 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 (430nm, 470nm, 565nm, 635nm) to set up their experiment.

The Vernier 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.

Vernier's 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 Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ 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.

Wired or Wireless — The Flexibility to Choose
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ app. No additional equipment or software purchases are necessary. Vernier 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.

  This product is used in teaching these Australian Curriculum codes:
  ACSBL021 - Biodiversity and the interconnectedness of life - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
  ACSBL029 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
  ACSCH069 - Molecular interactions and reactions - Rates of chemical reactions - The rate of chemical reactions can be quantified by measuring the rate of formation of products or the depletion of reactants
  ACSCH096 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Equilibrium position can be predicted qualitatively using equilibrium constants
  ACSCH091 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Over time, physical changes and reversible chemical reactions reach a state of dynamic equilibrium in a closed system, with the relative concentrations of products and reactants defining the position of equilibrium
  ACSCH131 - Structure synthesis and design - Chemical synthesis and design - Chemical synthesis involves the selection of particular reagents to form a product with specific properties (for example, pharmaceuticals, fuels, cosmetics, cleaning products)
  ACSCH133 - Structure synthesis and design - Chemical synthesis and design - Designing chemical synthesis processes includes identifying reagents and reaction conditions in order to maximise yield and purity of product
  ACSCH132 - Structure synthesis and design - Chemical synthesis and design - Designing chemical synthesis processes involves constructing reaction pathways that may include more than one chemical reaction
  ACSCH134 - Structure synthesis and design - Chemical synthesis and design - The yield of a chemical synthesis reaction can be calculated by comparing stoichiometric quantities with actual quantities
  ACSCH130 - Structure synthesis and design - Properties and structure of organic materials - Data from analytical techniques, including mass spectrometry, x­ray crystallography and infrared spectroscopy, can be used to determine the structure of organic molecules, often using evidence from more than one technique
