Fluorite Properties Fluorite is made up of calcium fluoride and has a transparent or translucent appearance. Sometimes it can be a colorless crystal, but other times it can also be purple, blue, green, yellow, or pink, or other combinations of these colors. Fluorite is sometimes called fluorspar. The name is derived from the Latin word âfluoâ, meaning to flow.
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light.These parameters are used to identify the presence and the amount of specific molecules in a medium.he machine is constructed like this to decrease the stray light from the upper beam that may strike the detector. The optimal angle is 90 degrees. There are two different approaches to handling the selection of incident light that gives way to different types fluorometers.
The mass potometer measures the water lost through transpiration of the plant and not the water taken up by the plant. 1  A potometer is a piece of apparatus used to measure the rate of water loss from a plant (transpiration).2  The rate of transpiration can be estimated in two ways: The potometer measures the rate of uptake of water. 2  To measure transpiration rate directly, rather than the rate of water uptake, utilize a scientific instrument which quantifies water transfer at the leaves. 3  The water retained by plant is so negligible that it can be neglected.
