Objective

Today's objective is to take UV and fluorescence spectrum again on the first and second dyed solutions to measure how time affects our measurements. Solutions haven't been shaken or moved too much since last time and the culot is still stucked at the bottom of our tubes, so we dind't centrifuge them again.

Protocol

  • Fluorescence and UV spectrum were taken with the same settings as previously; each solution was centrifuged before measurements.

Data

  • First solution UV spectrum.
