Description
ROTI®Antibiotic Discs Cefoxitin (CX) are ready-to-use paper discs impregnated with 30 µg cefoxitin for antimicrobial susceptibility testing in microbiology. Designed for standardised disk-diffusion workflows, they help laboratories assess bacterial response to this cephamycin antibiotic on inoculated agar media. The discs form part of the ROTI® Antibiotics Disks range from manufacturer Carl ROTH and are intended for professional life-science use. Defined antibiotic loading and uniform disc geometry promote clear, readable zones of inhibition when protocols are followed correctly. Typical applications include organism screening, quality-control checks, and comparative susceptibility studies alongside complementary culture media and incubators. With a pack weight of 0,052 kg, the format is practical for organised freezer inventory and cold-chain handling. These cefoxitin (CX) discs provide a convenient, batch-consistent tool for laboratories that require reliable antibiotic diffusion reagents without additional preparation steps.
This article belongs on Antibiotics & antimycotics, in Biochemicals & reagents.

Questions about ROTI®Antibiotic Discs Cefoxitin (CX), 30 µg, for microbiology, 50 unit(s)
What is this article?
ROTI®Antibiotic Discs Cefoxitin (CX), 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.
