Utilizes a locking ring which secures sterile velveteen squares onto a PVC cylinder for easy control of the plating device. To produce replicas, the Petri dish carrying microbial colonies is inverted and lowered onto the cloth surface, then lifted. A fresh sterile nutrient plate is then lowered onto the velveteen surface and lifted, leaving a replica of the original colonies in the new dish.
