GRAM & Zeihl-Neelsen Dual Stainer AT-3002


DAGATRONICS was founded in 1991. It is a high-tech enterprise, focusing on R&D of auto stainer. It is also one of the earliest enterprises to start R&D of auto stainer. As one of the three main manufacturers of bacterial auto stainer in the world, with its excellent quality (many patents and sertificates) and high valued price, it has been favored by hospitals and institutions all over the world. The products are exported to Europe, America, Southeast Asia, Taiwan, other countries and regions.

AT-3002 auto stainer can be used for two kinds of staining, GRAM staining and Zeihl-Neelsen staining. GRAM staining mode can automatically stain smears containing microorganisms, which can be used to detect Gram-positive and Gram-negative bacteria. Zeihl-Neelsen staining mode can automatically stain samples containing acid-fast bacilli such as body fluid, culture and secretion with AFB. The heating device can automatically perform Zeihl-Neelsen staining. Compared with manual staining, it is safe, accurate, convenient and time-saving.


1. Two kinds of staining, GRAM staining and Zeihl-Neelsen staining 

2. Reducing the influence of human factors  

3. Automatic staining

4. Reduce the use of reagents

5. Accurate, microprocessor-controlled staining

6. Clean trays and nozzles with alcohol and distilled water

7. No cross-contamination in all processes 

8. Check the reagent. If reagent content is too low, the alarm will be warned.

9. Reagents can be added separately

10. German KNF diaphragm pump, with life of 10,000 hours
