Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...
Methylthioninium chloride, commonly called methylene blue, is a salt used as a dye and as a medication. As a medication, ...
In hemocytometry, Türk's solution (or Türk's fluid) is a hematological stain (either crystal violet or aqueous methylene blue) prepared in 99% acetic acid (glacial) [1] and distilled water. The solution destroys the red blood cells and platelets within a blood sample (acetic acid being the main lyzing agent ), and stains the nuclei of the ...
For color blind people (or in backgrounds where detecting red bacteria is difficult), Victoria blue can be substituted for carbol fuchsin and picric acid can be used as the counter stain instead of methylene blue, and the rest of the Kinyoun technique can be used. [6] Various bacterial spore staining techniques using Kenyon e.g. Moeller's method
It is used to stain collagen. If blue is preferred to green, methyl blue or water blue can be substituted. Standard applications: Masson's trichrome staining is widely used to study muscular pathologies (muscular dystrophy), cardiac pathologies , hepatic pathologies or kidney pathologies (glomerular fibrosis). It can also be used to detect and ...
Aniline Blue WS, also called aniline blue, diphenylamine blue, China blue, or Soluble blue, is a mixture of methyl blue and water blue. It may also be either one of them. [ 1 ] It is a soluble dye used as a biological dye, [ 2 ] in fluorescence microscopy , appearing a yellow-green colour after excitation with violet light. [ 3 ]
The dye is structurally related to methylene blue, which also features a phenothiazine core. [1] The dye's name is frequently misspelled with omission of the e, and is not to be confused with the plant protein thionin. The -ine ending indicates that the compound is an amine. [2] [3]
Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.
