    antibiotic disc

  • Disc are easy to use and give a visual for students to understand how antibiotics work. To make them stick to agar, lightly tap the top of the disc. I use the wooden end of a cotton tipped applicator, but even a pencil, lead end, would work. Just make sure that what you use is smaller in diameter than the disc.

  • Discs are great. Perfect way to help understand bacterial classification and sensitivity.
    Used these for a high school microbiology lab.

  • They worked fine. You will need to use forceps to manipulate them. Also, be warned that when you incubate your agar plates upside down, sometimes the disks fall off. I appreciate HST's providing equipment and reagents in the small quantities needed by homeschoolers, in contrast to bulk quantities used by traditional schools.
