Disinfectant Test Methods
Perfectus Biomed offer a range of planktonic and biofilm disinfectant testing methods. Disinfectant testing methods ascertain the activity of antimicrobial agents under specified conditions.
We work with clients to generate evidence in support of products that consistently remove or inactivate pathogens. Our disinfectant testing can be carried out on inanimate surfaces with and also without interfering substances. Our team of PhD microbiologists are available to discuss method adaptations with you. We can also custom design disinfectant testing that meets with your requirement.
The Disinfectant Tests that We Offer
Traditional disinfectant testing focuses on planktonic isolates. They are typically easier to kill and less persistent than multispecies biofilm-encased microorganisms. Perfectus Biomed recognise that, in nature, an estimated 80% of microorganisms exist within polymicrobial biofilms. With this in mind, we design test methodologies that produce meaningful data.
Perfectus Biomed can provide a number of disinfectant tests, including carrier tests, suspension tests, capacity testing, practical and in use testing. We offer these tests in line with standard test methods including; BS EN 1040, BS EN 1276, BS EN 1650, BS, EN 1656, BS EN 1657, BS EN 13727, BS EN 13624, BS EN 13697, BS EN 13704, BS EN 14476, BS EN 14675, BS EN 14561, ASTM E2197-11, ASTM E2414-05.
If you do not see the disinfectant test you are looking for, please call us to discuss your requirements further.
Disinfectant testing supports infection control in both healthcare settings and in the community. Microorganisms spread by direct and indirect contact and can persist on hard surfaces for prolonged periods of time. Disinfectant manufacturers make claims around their antimicrobial activity relating to time of kill, persistence on a surface and residual activity.
Experts at Perfectus Biomed will work with you to design test methods that replicate ‘real life scenarios’ that demonstrate the efficacy of disinfectant products against potential pathogenic microorganisms, including those that exist within a microbial biofilm.
