FOLLOWING THE DYEING OF WOOL IN REAL-TIME USING FLUORESCENCE MICROSCOPY

The novel design of a heated stage (miniature dye bath) for use with a n inverted fluorescence microscope is described. The heated stage allo ws investigation of wool dyeings to be followed in situ in real time. The photometer attachment of the microscope allows for quantitative an alysis. The progress of the dyeing of wool with a fluorescent whitenin g agent and a fluorescent dye have been monitored in real time. (C) 19 96 American Institute of Physics.
