hey guys,

 

Does anyone use petri films for environmental monitoring?

Just curious...

when using a sponge swab, how much buffer do you add to the bag with the sponge?

for a 1:10 dilution?  90 grams of buffer

 

Thanks

Hi Jiljilbean,

 

Used to work for a place that did - but we had several highly micro qualified people on staff.

 

If you haven't got an existing lab with equipment and folks that really know the stuff I highly recommend using a third party near you. Especially if you have a testing frequency that is weekly or less often.

 

At another company we were looking to build the capacity in-house but were recommended by someone else who had gone that route that the hassle/cost to do it in-house is not worth it - especially considering that your auditor and more importantly customers are going to look much more favorably on a third party if you do not have a well developed lab.

 

Good luck!

(1) Yes, 3M have commercialized this application.

 

(2) Swab details typically depend on the kit instructions


Kind Regards,

We used plates, but only to test air for yeast and mold...................my coworker in crime has a MSc in micro so I do not question what she tells me


Because we always have is never an appropriate response!
