Disk & Agar Diffusion

 

 

 

 

Reliable, Visual Antimicrobial Profiling

At FWRM Labs, we perform disk and agar diffusion assays to measure phage and antimicrobial activity with precision and consistency.
These assays provide a visual, quantitative representation of inhibition zones, offering clear insights into antimicrobial efficacy, phage potency, and bacterial susceptibility across clinical and agricultural applications.

Our testing supports comparative analysis, method validation, and quality control, helping teams evaluate and optimize their products and research outcomes with confidence.

Service Overview

Disk and agar diffusion methods are well-established, standardized techniques for assessing antimicrobial and phage activity.
By placing antimicrobial agents or phage preparations on agar surfaces inoculated with bacterial targets, we measure the zone of inhibition—the area where bacterial growth is visibly suppressed.
These results deliver both qualitative and quantitative data, forming a critical component of early screening, formulation development, and potency verification studies.

At FWRM Labs, each assay is executed under validated conditions to ensure reproducibility and regulatory readiness.

What We Deliver

Our Disk and Agar Diffusion testing services provide:

  • Accurate zone measurement and data interpretation

  • Digital imaging and traceable results for documentation and review

  • Comparative efficacy analysis across multiple antimicrobial or phage agents

  • Full report packages, including assay metadata, method reference, and raw data export options

Results are reviewed by our QC/QA team to verify accuracy and consistency across replicates, ensuring defensible data for research and submission purposes.

Our Approach

Each diffusion assay performed at FWRM Labs follows a defined workflow designed for precision and transparency.
We tailor every test based on your target organisms, phage or antimicrobial type, and desired data output—whether the goal is to compare formulation efficacy, validate a new assay method, or generate supporting data for regulatory documentation.

Our protocols are built around recognized standards (including CLSI and ISO) and can be adapted for both phage-based and antimicrobial compound testing.

Applications Across Research and Development

Disk and agar diffusion assays are versatile tools used across the spectrum of microbiological testing.
At FWRM Labs, they play an essential role in:

  • Phage host range analysis and potency screening

  • Antibiotic and antimicrobial formulation testing

  • Comparative efficacy studies

  • Method validation and cross-platform reproducibility assessments

  • Preliminary screening for resistance or susceptibility patterns

Whether applied in a clinical, agricultural, or industrial context, these assays provide fast, visual insight into bacterial inhibition performance.
