Fermentation Tube
Designed to verify and measure gas production in fermentation experiments. The
borosilicate glass tube traps the gas (CO2) as it is evolved. Use fermentation tubes
to conduct comparative studies with different microorganisms or with a variety of
fermentable sugars. Vertical tube is graduated up to 5 mL in 0.1 mL divisions—so gas
volume can be precisely quantified.

Antibiotic Sensitivity Disks, Difco
These disks are used to test the effectiveness of particular antimicrobial agents (antibiotics)
against specific target organisms. The number given after the name of each
agent is the dosage per disk in micrograms. An organism is considered sensitive if
the resulting zone of inhibition is greater in diameter than the intermediate range
given, and insensitive if less. A quantity of disks is supplied sterile-packed sleeves.
Required disk dispenser sold separately. Note: Keep refrigerated, and use within six
months of purchase.
