Fluorescence Spectrophotometer F93 A Configuration, 1×10^-9 Detection Limit (CAT#: STEM-AL-8825-ZJF)

The F93 A Configuration is a fluorescence spectrophotometer intended for fluorescence measurement of proteins, nucleic acids, dyes, and fluorescent markers. It uses LED excitation and manual monochromator scanning to select measurement wavelengths. The source describes measurement of fluorescence intensity and emission spectra from multiple fluorescent sample types. A photomultiplier-tube receiver is used for fluorescence signal detection. The configuration includes selectable excitation bandwidth and a fixed emission bandwidth. The specified wavelength ranges support visible-region excitation with emission measurement extending into a broader spectral region. The normalized record retains only technical information supported by the source. Overall, the A configuration provides a straightforward fluorescence platform for routine sample analysis.
