What is a vernier spectrophotometer?

Powered by Ocean Optics™ technology, the Vernier Spectrometer is a portable VIS-NIR spectrometer which connects directly to your computer with a standard USB cable. It is a fully functioning spectrophotometer that gives precise measurements instantly over a range of 380–950 nm.

How does the SpectroVis spectrophotometer work?

The Go Direct SpectroVis Plus Spectrophotometer employs an LED and tungsten bulb to transmit light through a high-quality diffraction grating. The diffracted light is sorted and collected by the linear CCD array detector.

What does a SpectroVis do?

The SpectroVis Plus is a portable spectrophotometer that measures both the absorbance and the percent transmittance of a solution. It comes with 15 plastic cuvettes and lids, a USB cable, and a user’s guide. This product can measure wavelengths from 380 to 950 nm, with wavelength intervals of 1 nm.

How do you calibrate a vernier spectrophotometer?

To calibrate the SpectroVis Plus, choose Calibrate ► Spectrophotometer from the Experiment menu. Note: For best results, allow the Spectrophotometer to warm up for a minimum of five minutes. Fill a cuvette about 3/4 full with distilled water (or the solvent being used in the experiment) to serve as the blank.

What is spectrophotometry used for?

Spectrophotometry applications are useful to measure the absorbance, reflectance, and transmission of light by gases, liquids, and solids.

How does a spectrophotometer measure concentration?

This article more specifically explores techniques when using a spectrophotometer to determine concentration of an analyte. A UV/VIS spectrophotometer measures the intensity of light passing through a sample solution in a cuvette, and compares it to the intensity of the light before it passes through the sample.

Why is spectrometer so called?

Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum.
