21. Below the bones is a space filled with cerebrospinal fluid that provides shock absorbance . 22. These may involve absorbance or fluorescence measurements. 23. The reagent is incubated with the sample and absorbance is then measured at 560 nm. 24. It is a function of the absorbance of light of wavelengths 510 and 610 nm. 25. The greater the absorbance at a certain wavelength of light, the greater the potency. 26. Isopropyl alcohol has a maximum absorbance at 205 nm in an ultraviolet-visible spectrum. 27. The absorbance reading of crocin is known as the " colouring strength " of that saffron. 28. Optical thermometers have been created by calibrating the change in absorbance of a material against temperature. 29. ? Absorbance records any change in the absorption spectrum as a function of time and wavelength. 30. The Bradford assay linearizes by measuring the ratio of the absorbances , 595 over 450 nm.
