For colony replication, the Petri dish with the bacterial colonies in it is overturned, pressed into the fabric surface of the colony replicating platform and then removed. A replica of the original colonies (now sitting on the replicating platform) is then obtained by inverting a sterile Petri plate with appropriate nutrient agar in it and pressing it into the velveteen surface of the replicating platform.
