ZEISS Primostar 3 iLED

Your LED-Fluorescence Microscope for Sputum Examination

Highlights

• Easily switch between fluorescence and brightfield illumination

• Identify details up to 4× faster than with brightfield microscopy*

• Special pricing for customers in countries most heavily affected by TB

* WHO notes LED fluorescence microscopy is more sensitive and less time-consuming than conventional brightfield for sputum smear microscopy. (See the WHO reference in the flyer.)

Overview

ZEISS Primostar 3 iLED helps you visualize small structures down to 0.2–5 µm, including rod-shaped Mycobacterium tuberculosis. Ziehl-Neelsen (ZN) staining with brightfield is the traditional gold standard, and LED fluorescence (e.g., with Auramine-O) provides a sensitive, time-saving alternative.

Applications & contrasting methods relevant to healthcare

• Stained tissue sections in medicine

• Unstained cells in phase contrast (medicine & biology)

• Examination and analysis of germs and bacteria in the lab and in field work

Mode switching

Quickly toggle between ZN brightfield and fluorescence excitation (e.g., Auramine-O) for TB analysis.

Representative images in the flyer show:

• Mycobacterium tuberculosis with Auramine-O in fluorescence (greenish-yellow particles on a dark background)

• Conventional ZN staining image (credit: Dr. med. Harald Hoffmann, WHO – Supranational Reference Laboratory IML, Gauting, Germany)

Special Features

• All optical components are anti-fungus treated

• LED intensity indicator panels on both sides of the stand

• Powerbank support
