PetriStickers allow for petri dishes to be labeled quickly, neatly and reliably.Made with water-resistant ink, substrate and adhesives, they will remain firmly attached at temperatures from 42? to 4?C.Simply remove the label's protective backing and apply it to the back of a petri dish.After labeling, the dish can be held in a comfortable position for streaking or colony transfer, stored in an incubator or refrigerator, and photographed.
