Based on experiences in the WHO Supranational Reference Laboratory of Tuberculosis, Gauting, Germany, tuberculosis may whether analyzed with Ziehl-Neelsen-staining or fluorescence excitation, e.g. Auramine O.
Primo Star iLED – Fluorescence Microscope
Observe microbiological structures
Primo Star iLED is your recommended microscope to visualize structures smaller than 0.5 µm with LED fluorescence excitation and transmitted-light brightfield illumination such as the rod-shaped bacterium Mycobacterium tuberculosis. Mycobacterium tuberculosis comes with a size of 2 – 4 µm in lengths and 0.2 – 0.5 µm in width.
