Description
ROTI®Antibiotic Discs Colistin (CL) are ready-to-use paper discs impregnated with 10 µg colistin for antimicrobial susceptibility testing in microbiology. They are intended for disk-diffusion workflows that examine bacterial response to this polymyxin antibiotic, which remains relevant in studies of multidrug-resistant Gram-negative organisms. The product belongs to the ROTI® Antibiotics Disks range from manufacturer Carl ROTH and is aimed at professional laboratory use. Uniform disc geometry and defined antibiotic charge support clear zone reading when validated culture and incubation conditions are observed. Applications include isolate screening, quality-control checks, and comparative susceptibility work alongside appropriate agar media. With a pack weight of 0,041 kg, the unit is convenient for organised cold storage and inventory control. These colistin (CL) discs give microbiology teams a practical, ready-to-apply reagent format for diffusion-based antibiotic testing without additional impregnation steps.
This article belongs on Antibiotics & antimycotics, in Biochemicals & reagents.

Questions about ROTI®Antibiotic Discs Colistin (CL), 10 µg, for microbiology, 50 unit(s)
What is this article?
ROTI®Antibiotic Discs Colistin (CL), 10 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.
