Thanks King studs ruler. Yeah I checked out the filter(suction cup - ours is the same just a different brand.
We use petrifilm but you can also just take the filter on petrifilm pre moistened with sterile buffer. Thats what we do for potable water testing. :)
It seems like a great idea.
I am imagining:
Take 10g sample, 90 g buffer... homogonise/stomacher... then filter. So the sensitivity would end up being <1cfu/10g instead of being <10cfu/g, right?
First we have technically only 'tested' 0,1g, but in the suggested method we are testing 10g.
I love it!
Can see where you are coming from with the sampling.... Dollars and time, dollars and time.
We do a 'stress test' for the samples where they are left out at ambient and then tested at EOL.
Any more input is welcome :D
Thanks
