Cuvette Rack

The Colorimeter is great for Beer’s law experiments, determining the concentration of unknown solutions, or studying changes in concentration vs. time. This 4-wavelength Colorimeter measures the amount of light transmitted through a sample at a user-selectable wavelength in order to determine the concentration of a solution. Features such as automatic sensor identification and one-step calibration make this sensor easy to use. Range:0 to 3 (absorbance) Useful Range:0.05 to 1.0 (absorbance)90% to 10% transmittance (%T) Wavelengths:430 nm, 470 nm, 565 nm, 635 nm User manual

Paquet de 100 semi-micrométrique (1 - 1,5 ml) et 20 couvercles des cuvettes.

Un paquet de 100 couvercles de cuve pour une utilisation avec plastique cuvettes VIS-NIR ou cuvettes UV-VIS.

Increase student engagement in your laboratory and classroom with the Go Direct Visible Spectrophotometer. Its quality optical bench allows for high accuracy and reproducibility, making this spectrometer an ideal option for upper-level courses. In addition, the spectrometer housing is aluminum, which helps alleviate temperature fluctuations during a long kinetics experiment.  The Go Direct Visible Spectrophotometer comprises a lamp with cuvette holder and a detector. These two pieces are held together magnetically, allowing them to be easily separated for high-accuracy emissions experiments with our Vernier Emissions Fiber.  To collect spectral, kinetic, or Beer’s law data, simply connect the Go Direct Visible Spectrophotometer directly to a tablet, laptop, or Chromebook™, via USB or Bluetooth® wireless technology. Data can be collected and analyzed using our LabQuest® 2, LabQuest 3, or free Vernier Spectral Analysis® software, which allows users to spend less time learning different interfaces and more time in the laboratory. The Go Direct Visible Spectrophotometer can be used in a variety spectroscopy experiments: Determine peak wavelength to collect data on solution concentration for studies of Beer’s law or to monitor rates of reaction.  Conduct enzyme kinetics experiments. Engage in equilibrium studies of absorbance vs. time or absorbance vs. concentration. Use the Spectrophotometer Optical Fiber to measure emissions from flame tests or other light sources.  Specifications Wavelength range: 380 nm–950 nm Reported wavelength interval: ~1 nm between reported values Optical resolution (FWHM): 3.0 nm Wavelength accuracy: ± 2.0 nm Absorbance photometric accuracy: ± 0.05 A.U. Typical scan time: ~2 s

Un paquet de 100x 3,5 ml (cuvettes avec 20 couvercles) est disponible pour une utilisation avec notre colorimètre (COL-BTA), SpectroVis Plus (SVIS-PL), et Vernier Spectrometer (V-SPEC).

Package of two Starna Cells quartz cuvettes (3.5 mL) and two lids.

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.
