Ethanol prices have tripled since 2020 making the use of 70% ethanol non viable. I am looking to buy bulk quantity of disinfectant for our new laminar flowhood.
I am wondering which type of disinfectant are you using in your laminar flowhood and why?
Based on current research I am convinced that quaternary ammonium disinfectants are the most effective and economical and I am leaning towards them but I would like the opinion of other fellow microbiologists.
Thank you
I would like to suggest reading the paper entitled "The Process of Cleaning a Laminar Airflow Hood"
Mr. Pedraza's suggestion is excellent. I just want to mention that the product used should depend on the type of manipulation that is carried out in the Airflow hood. Example: preparation of drugs or for manipulations in microbiology. It is important to note that the product should not leave any residue on the surface once dry. The use of quaternary ammonium could therefore require rinsing with water in certain situations. Concerning alcohol, if it is used for the interior disinfection of the hood, it is necessary to think of stopping the ventilation because the contact time will not be sufficient to have a full disinfecting effectiveness.
Jorge Morales Pedraza Hello and thank you for you answer. I cant find a paper with the title "The Process of Cleaning a Laminar Airflow Hood"... Would you happen to have a doi number or the name of the author and journal or date published? thank you!
Alcohol (70% EtOH) does not require significant contact time. It's effect on vegetative cells is +/- immediate. That is your best option.
Quaternary ammonium compounds are commonly used as well - they do not require rinsing. e.g. https://us.ivfstore.com/products/oosafe-disinfectant-for-co2-incubators-and-laminar-flow-hoods
