Whatman 2017-006 Antibiotic Assay Paper, 6mm Discs, 1000/pk

In antibiotic susceptibility tests, the paper discs containing an antibiotic are placed on an agar plate inoculated with bacteria. During incubation, the antibiotic diffuses into the agar. If the bacteria are sensitive to the drug, a clear area known as a “zone of inhibition” forms around the disc, indicating reduced bacterial growth.

The 6 mm size is a standard format for disk diffusion testing, allowing consistent antibiotic diffusion and reliable comparison of inhibition zones between samples. This standardized size helps laboratories perform reproducible antimicrobial susceptibility tests.

Yes. The discs are typically supplied blank and ready to absorb liquid antibiotic or chemotherapeutic agents, allowing researchers to prepare customized test discs for evaluating different antimicrobial compounds in laboratory experiments.

Antibiotic assay discs are widely used in clinical microbiology labs, pharmaceutical research facilities, biotechnology labs, and academic institutions. They are commonly applied in antibiotic screening, drug discovery, and bacterial resistance studies.

The Ohaus Achiever 5000 overhead stirrer is designed for mixing, dissolving, dispersing, and homogenizing liquids in laboratory and pilot-scale applications. Overhead stirrers are commonly used when mixing larger volumes or higher-viscosity samples that cannot be handled efficiently by magnetic stirrers.
