This morning a pipette vender came and talked about the benefits of the pipette tips he was selling. It was very interesting to hear about all the technology that goes into the basic lab equipment that scientists use every day. Later today I rehydrated the ovalbumin I previously microglass-ified and analyzed it with UV spectroscopy and prepared it for size-exclusion chromatography. Although I did not do much today, at least compared to yesterday, I enjoyed being able to practice UV spectroscopy and learning about size-exclusion chromatography.
