Glass Plating Beads (Sterilized)

Sterilized glass plating beads (4 mm) provide an efficient and easy method to achieve optimal spreading on agar plates. The rolling action of the glass beads gently spread the E. coli solution (or any bacterial /fungal solution) to reach areas of the plate that are inaccessible to spread. Multiple plates containing beads and E. coli solution may be stacked and shaken simultaneously to increase spreading throughout and reduce cell stress. The beads may be recovered by washing with 70% ethanol, then sterilized and dried.

Features
• Pre-sterilized
• No flaming required

Protocol for plating bacteria and yeast
• Pipet the cells on the plate, add 5 to 10 beads, and move the plate back and forth a few time. The beads’ rolling action gently spreads the cells evenly and completely over the agar surface. Entire stacks of plating, pour the beads off the plate and it is ready for the incubation.
