The FL 6500 Fluorescence Spectrometer is the optimal system for analyzing samples susceptible to photo-bleaching. Photo-bleaching may be experienced with certain thin coatings and compounds in bioresearch, cell-biology, molecular biology, immunology, enzymology, tissue and protein samples; FL 6500 is also excellent for phosphorescence analysis.

Class practical. Escherichia coli (E. coli) can produce the enzyme β-galactosidase which breaks lactose into galactose and glucose.However, the gene for β-galactosidase is normally switched off, except in the presence of lactose. In this procedure, a sample of E. coli is treated with lactose, and then the β-galactosidase activity of this sample and an untreated sample are compared.

The Spectronic 20 is a brand of single-beam spectrophotometer, designed to operate in the visible spectrum across a wavelength range of 340 nm to 950 nm, with a spectral bandpass of 20 nm.
