Pre-sterilized Made of unbreakable polystyrene L-shaped design for convenient and simple spreading Lazy-L-Spreaders allow the user to simply turn the petri dish 360° to achieve a smooth and even sample distribution. A smooth spreading surface with a slight upward turn reduces the likelihood that the spreader will dig into the agar. Pre-sterilization eliminates flaming or autoclaving and reduces the risk of contamination. Spreaders also eliminate the wasted time involved in waiting for glass or metal spreaders to cool before use. (500 per PK)
