ASTM E Antimicrobial Kill Time Testing Microbiology Lab – Accugen Laboratories is a microbiological testing Lab offering ASTM E Kill Time. The suspension-based time-kill test has been standardized by ASTM International, as ASTM E – “Standard Guide for Assessment of Antimicrobial Activity. The ASTM E Time Kill Assay for Antimicrobial Agents test is a suspension- based method which can be used to provide general rate-of-kill.

ASTM E Time Kill Assay for Antimicrobial Agents – December 5, – Accuratus Lab Services

Variables in the test are required to be standardized. As an example, test results of microorganisms requiring growth supplements, or special incubation conditions, may not be directly comparable to more robust organisms under the conditions of a single procedure. When the technique is performed as a specific test method, it is critical that the above mentioned variables have been standardized.

The time selection is dependent on e2351 type and intended use of the test material.

The test parameters for suspension-based time-kill tests are easy to control in the laboratory setting, so comparisons can be made fairly easily between various products tested under the same conditions.

Strengths of the Suspension Time-Kill Test The impact of a topical antiseptic product on microorganisms over time otherwise known as a death or kill curve can be studied with relative ease using this suspension-based method.

The suspension time -kil l test is excellent for topical antiseptic product developers because it is a fast, relatively inexpensive, and reproducible way to measure the biocidal potential of a liquid antimicrobial formulation.

The way in which the microbial inoculum is prepared can have an impact on the test outcome, since different broths or suspensions may interact with or inactivate antiseptics.

The suspension-based time-kill test involves exposing microorganisms to excess product in zstm liquid setting, so the test is a fitting model system for instances in which antiseptics will be used in large volumes to kill microorganisms such as with submersion of hands into an antiseptic bath or for extended exposure rinses.

A contract testing laboratory designed to support the hand hygiene and infection control industry. Weaknesses of the Suspension Time-Kill Test The test method is difficult to relate to inactivation of microorganisms on the surfaces of human hands or other similar substrates.

ASTM E 5 Sus pension Time-Kill Test The suspension time -kil l test is excellent for topical antiseptic product developers because it is a fast, relatively inexpensive, and reproducible way to measure the biocidal potential of a liquid antimicrobial formulation.

Antimicrobial activity of specific materials, as measured by this technique, may vary significantly depending on variables selected.

The variables cover organism selection, inoculums preparation, sampling times and temperatures. It consists of directly inoculating a liquid test substance with a high concentration of test microorganisms and then determining the percentage killed over time. To measure initial microbial concentrations, a saline control is spiked with the same microbial culture and then enumerated. Antimicrobial activity of specific materials, as measured by this technique, may vary significantly on variables selected.

The purpose and importance of this ASTM E test or also known as the Liquid Suspension Time-Kill Test, is that it can used to evaluate the decrease of a microbial population test organism after exposure to certain Disinfectant products and materials.
