Elder Scrolls Online will remove its subscription fee and will be free to play starting on March 17. Players can purchase the game now renamed The Elder Scrolls Online: Tamriel United at one time and continue playing it for free onwards.
NIST Traceable reference standards for verifying the wavelength accuracy of a UV/VIS spectrophotometer. All standards are stringently prepared according to NIST guidelines.NSG's solid-state standards never need to be replaced due to material aging and come with a unique lifetime warranty.IST Traceable reference standards for verifying the wavelength accuracy of a UV/VIS spectrophotometer.

A spectrophotometer is an instrument that can pass light of a single wavelength through a solution and measure the amount that passes through. First, the spectrophotometer must be zeroed by passing light of the chosen wavelength (500 nm for example) through a blank containing only the solvent. spectrophotometer can be set to measure either the percent transmittance or the absorbance of a solution. In lab, you will be using a spectrophotometer called the Spectronic 20 or Spec 20 to measure absorbance.
