Science Buddies: "Ask an Expert"

My son is doing a project testing natural rem against antibiotics.
My question is what size difussion disc should I order. I found one that is 6mm. Is that large enough for one per plate?

Its the little things that drive you crazy.

Thanks in advance.

I was hoping someone with more experience with diffusion discs would respond but since no one has I found a document on the web at:
http://www.bsac.org.uk/_db/_documents/v ... t2002_.pdf

that seems to be a very good step-by-step process for evaluating antibiotic effects using diffusion discs.

Good luck.

Thanks

This was more help than just size.


Hoping our kids love science as much as we do!,
