Did you know the FDA requires all antibiotics to go through potency testing before they are released in the United States?

Our USP <81> Antibiotic Potency Testing services validate your product’s antibiotic efficacy and preserve patient safety. We employ the cylinder plate method described in USP Chapter <81> and depends on diffusion of the antibiotic from a vertical cylinder through a solidified agar layer. The growth of specified microorganisms inoculated into the agar is prevented in a circular “zone” around the cylinder containing the solution of the antibiotic.

We can test many antibiotics, including

  • Vancomycin
  • Nystatin
  • Erythromycin
  • Many others

This service complements our existing suite of pharmaceutical safety testing and environmental monitoring solutions. And our team has the experience you need in a testing partner to ensure high-quality results.

Don’t compromise on your antibiotic’s integrity – contact us to learn more about how we will partner with you to safeguard your product.
