What is the device used to measure percent light absorption in pigments?

AI Thread Summary
The device used to measure percent light absorption in pigments is a spectrophotometer. This instrument is user-friendly and allows for the analysis of light absorption by placing sample tubes into the device, which then displays the absorption values. Spectrophotometers are not specifically designed for pigments but are versatile tools commonly used in various biological and chemical applications.

What is the device used to measure percent light absorption in pigments?

I remember finding the percent light absorption in the pigments of some vegetables for a high school bio lab. I am pretty sure the device used was not specific for pigments. The device was user friendly- we just stuck some tubes in a magical box and the box displayed a number.

Thread 'New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours'

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
