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.
