They are intended for the quality control of stain reagents and staining methods. Those tools, by facilitating the QC procedures, are a perfect and natural complement to our slide stainers Aerospray™ TB and Aerospray™ GRAM.


The unique ELITech stain control slides offer key advantages:

  • Convenient and cost-effective approach for evaluating and controlling the quality of GRAM and ACID FAST staining procedures
  • Prepared slides to eliminate the need for maintaining stock cultures to prepare slides
  • Helps to standardize laboratory procedures
  • Simulate clinical smears with appropriate amount of background material

Reagents and material

The Gram Stain control slides are prepared from standard quality control organisms. Our Gram Stain Control slides have two wells containing a Gram positive control organisms (Staph. aureus) and a Gram negative control organism (E.coli) which have been made non-viable. Space is provided on the slides for writing data. Materials are supplied ready to use. The Acid Fast Control Slides simulate a clinical sputum smear with appropriate background material. They have been prepared for use for staining with Ziehl-Neelsen, Kinyoun or fluorescent techniques. Acid fast control slides are intended for the control of stains used for routine staining of sputum and body fluids forMycobacterium tuberculosis. It is solely intended for in vitro diagnostic analysis. It is solely intended for in vitro diagnostic analysis. Slides have two wells containing a positive control Mycobacteria tuberculosis strain H37ra 25618 and a negative control of E.coli. The distribution of the background material has been made to simulate a patient’s specimen. 50 slides (according to the reference) are provided. Materials are supplied ready to use.
