Zone of Inhibition Test for Antimicrobial Activity

A Zone of Inhibition Test, also called a Kirby-Bauer Test, is a qualitative method used clinically to measure antibiotic resistance and industrially to test the ability of solids and textiles to inhibit microbial growth. Researchers who develop antimicrobial textiles, surfaces, and liquids use this test as a quick and...

Rinsability Test

In the usage of high-level disinfectants, the possibility of contact with these substances is something that needs to be ensured does not occur if the active ingredient could be harmful. To ensure that the level of active ingredient in/on the surface in question is at a level that would...

Simulated Use Test for High-Level Disinfectants

Prior to initiation of the experiment, the active ingredient in the test substance is measured, the pH is taken and the concentration of the test substance is validated using titration analysis. Then, the test substance is diluted to the minimum recommended concentration (MRC) and confirmed again by titration analysis...

MIL-STD-810G Method 508.6 Fungal Resistance Test

The MIL-STD-810G are a series of laboratory standards designed by the United States military to test the endurance capabilities of materials based on the expected field conditions they will meet during their lifetimes. Method 508.6 is a material fungal resistance test developed to determine if the material components comprising the...

Minimum Bactericidal Concentration (MBC) Test

The MBC test determines the lowest concentration at which an antimicrobial agent will kill a particular microorganism.  The MBC is determined using a series of steps, undertaken after a Minimum Inhibitory Concentration (MIC) test has been completed. MBC testing is useful for comparing the germ-killing activity of several antimicrobial agents at once. Summary...

Hard Surface Time-Kill Test for Disinfectants

Summary of the Hard Surface Time-Kill Test     A microbial culture is prepared. For most bacteria, a 24 hour culture in nutrient broth works well. For most fungi, a spore preparation from a saline wash works well.   A volume of microbial culture (usually 0.010 ml to 0.020 ml) is placed onto the...

Pre-Saturated Towelette Disinfection Test

The EPA pre-saturated towelette disinfection test method is used to substantiate efficacy claims for disinfectant towelettes.     This method is a modification of the AOAC Germicidal Spray Products Test for Disinfectants. Instead of contaminated test surfaces being sprayed with disinfectant as in the germicidal spray products test, they are wiped with...
