How much should be the contact time of plate to the surface sample
There's no set time but the time it takes to roll the plate over the sample should suffice.
Just roll the plate across so the entire surface of the rodac is completely contacted. There is no reason to let go of the plate and let it sit there
Kindly upload a video for environmental and air culture guideline good video
