Liquid Suspension Time-Kill Test

The liquid suspension time-kill test is excellent for disinfectant product developers, because it is a fast, relatively inexpensive, and reproducible way to measure the biocidal potential of a liquid antimicrobial formulation. It consists of directly inoculating a liquid test substance with a high concentration of test microorganisms, then determining the percentage killed over time.

The suspension-based time-kill test has been standardized by ASTM, as ASTM E2315 "Standard Guide for Assesment of Antimicrobial Activity Using a Time-Kill Procedure."
