Zymo Research offers Rattler Plating Beads to save the researcher time and effort when plating bacteria or yeast. The sterile glass beads are simply poured onto solid plated medium together with a liquid cell suspension, and the mixture is shaken to distribute the cells evenly over the medium's surface. This allows for numerous plates to be processed quickly and efficiently. Pour the Rattler Beads onto a series of plates, stack, and shake simultaneously in a side-to-side motion. The beads can be easily removed following inversion of the plates and pouring off from the plate lids. Using the Rattler Plating Beads is simple, easy, and saves you time. The beads come sterile in polycarbonate bottles and can be reused following cleaning and washing.
