DESCRIPTION

Use sterile sensitivity disks to test a substance's effect on bacteria growth or as a control. Which common household cleaners are most effective at inhibiting bacteria growth? Find out with these sterile sensitivity discs.

It's easy to experiment with sterile sensitivity disks and common disinfectants. To avoid contamination, use sterile tweezers to handle disks. Use a clean pipet to put an equal and precise amount of each cleaner you're testing on a sterile sensitivity disc. Place the disc on a cultured agar plate. Wait at least a few days, and compare the size of the inhibition zone!

How do natural disinfectants (like honey, vinegar & tea tree oil) stack up against commercial cleaners? Make a hypothesis and put it to the test! You get a disposable vial of 50 sterile sensitivity discs (also spelled disk and shortened to sensi-disk). Each sensi-disc measures 1/4" in diameter.
