I would like to measure bioburden of items from lab into cleanroom then into various grade areas. I will be using contact plates however im unsure as to what limits i should be using. Is there a standard for this?

thanks

Re: validation of transfer materials

Hi Laura! Thanks for dropping by the Cove!

Exactly which limits are you interested in? I would think your contact plates are positive/negative type tests. Or, are you interested in running the tests on the contact plates?

Re: Validation of transfer materials

Hi Brad,

Im looking for what sort of reduction in colony counts i may get from transfering an item that has not been disinfected to an item that has. This will be measured by applying a contact plate to the item. What number of colonies on the item would be acceptable to allow into say for example an ISO class 8 environment?

Regards
