FB1759 I $26.55Spontaneous Generation—Demonstration KitPrior to Louis Pasteur, it was believed that living microbes could arise from nonliving matter by spontaneous generation. Pasteur’s classic S-tube flasks proved key in dispelling this belief, and now your students can easily duplicate this classic experiment that exposes media-filled flasks with different openings and treatments to air containing microbes. Only in flasks where microbes come in direct contact with the media become contaminated.
