What is an anaerobic system?
An anaerobic system is a controlled environment that lacks oxygen, designed specifically for cultivating anaerobic microorganisms or conducting reactions that require the absence of oxygen. These systems include specialized chambers, jars, and other equipment that maintain anaerobic conditions.
How do Gaspak anaerobic jars work?
Gaspak anaerobic jars create an oxygen-free environment by using a gas-generating sachet that reacts chemically to remove oxygen and produce carbon dioxide and hydrogen. The jar is sealed, and the reaction inside the sachet depletes oxygen, creating the anaerobic conditions necessary for the growth of anaerobic organisms or other experiments.
What types of organisms can be grown in Gaspak jars?
Gaspak jars are used to grow anaerobic organisms, such as obligate anaerobes, which cannot survive in the presence of oxygen. Examples include Clostridium species, Bacteroides species, and other bacteria that thrive in oxygen-free environments.
How long do anaerobic conditions last in a Gaspak jar?
The anaerobic conditions in a Gaspak jar can typically last for 24-48 hours, depending on the seal of the jar and the effectiveness of the gas-generating sachet. For longer experiments, additional measures may be needed to maintain the anaerobic environment.
What is the purpose of the indicator strip in Gaspak jars?
The indicator strip in Gaspak jars changes color to visually confirm the creation of anaerobic conditions. Typically, the strip contains a redox dye that is colorless in the absence of oxygen and colored in its presence, providing a quick check that the environment inside the jar is anaerobic.
