Upright Microscopes
Primo Star iLED
Continuing a tradition started by Robert Koch: Research tuberculosis with a microscope from Carl Zeiss
In 1882, Robert Koch using a Carl Zeiss microscope discovered Mycobacterium tuberculosis, the pathogen that causes tuberculosis.

Here is another substantial technology contribution from Carl Zeiss to the battle against infectious diseases: Primo Star iLED, the new fluorescence microscope.

Primo Star iLED enables you to analyze microscopic tubercle bacilli with transmitted-light brightfield illumination. Due to the small size of the pathogen stained according to Ziehl-Neelsen, you usually work with a 100 x objective. At this magnification rate the visible object field is very small. The scanning of the specimen therefore is relatively time-consuming. The tubercle bacilli stained in violet are hardly visible.In the LED-based fluorescence microscope Primo Star iLED, tubercle bacilli stained with, e.g., Auramine O, conspicuously glow in yellow to greenish hues against a dark background. Due to this fact and the use of a 40 x objective with larger object field the detection of the pathogens is about 4 times faster and about 10% more sensitive than Ziehl-Neelsen method.
Your Decision:
Decide for yourself if you want to analyze tuberculosis according to Ziehl-Neelsen-Staining or if you like to use fluorescence excitation, e.g. with Auramine O dye.
Primo Star iLED gives you the opportunity: simply switch between the two modes.

Primo Star iLED Switch
Due to simple switching between fluorescence and brightfield, Primo Star iLED is flexibly applicable.
Special Price for High Burden Countries
The microscope Primo Star iLED is the result of a cooperation between Carl Zeiss and the
Foundation for Innovative New Diagnostics (FIND).
The success of this cooperation speaks for itself: the health organisations of the 74 "most concerned countries "
