Description
ROTI®Antibiotic Discs Nalidixic acid (NA) are microbiology discs impregnated with 30 µg nalidixic acid for antimicrobial susceptibility testing. They are applied in disc-diffusion assays to examine bacterial response to this quinolone agent on inoculated culture media. As part of the ROTI® Antibiotics Disks line from manufacturer Carl ROTH, the NA-coded discs deliver a defined antibiotic load for standardised placement on agar plates. Laboratories use them when determining inhibition zones under established incubation and reading conditions. The product falls within life-science categories covering antibiotics and antimycotics and supports Kirby-Bauer-type or comparable diffusion methods. Clear NA designation simplifies identification in multi-disc configurations and susceptibility layouts. Each disc is intended for direct application in line with validated local procedures and quality systems. These discs help structure everyday susceptibility workflows wherever nalidixic acid is included in the antibiotic panel under evaluation.
This article belongs on Antibiotics & antimycotics, in Biochemicals & reagents.

Questions about ROTI®Antibiotic Discs Nalidixic acid, (NA), 30 µg, for microbiology, 50 unit(s)
What is this article?
ROTI®Antibiotic Discs Nalidixic acid, (NA), 30 µg, for microbiology, 50 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Antibiotics & antimycotics, inside Biochemicals & reagents, in Life Science & Microbiology.
An antibiotic or an antimycotic for laboratory use is specified by potency, often micrograms per milligram, and by the spectrum it is used for in media. A hydrate and a free base differ in mass. Sterile solutions ready for culture and the dry powder are different articles. This is not a medicine for a patient.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
