Anaerobic Gas System – PetriSphere

Manufacturer: BioTool Swiss AG
SKU: anaerobic-gas-system-petrisphere


Anaerobic chambers are tools that are used in laboratories to provide an oxygen-free, i.e. an anaerobic environment, for researchers who work with oxygen-sensitive materials. Simply put, a hydrogen (H2) gas mixture is circulated through a heated palladium catalyst that removes oxygen (O2) by forming water (H2O). Anaerobic gas systems are tools that are used for cultivating anaerobic microorganisms. These obligate anaerobes can only survive in the absence of oxygen since these organisms lack the enzymes superoxide dismutase and catalase, which destroy any lethal superoxide radicals that are formed in the presence of oxygen. Towards this end, Neutec proudly offers Biotool Swiss’ new PetriSphere Gas-System. This anaerobic gas system consists of a microprocessor-based controller connected with a diaphragm vacuum pump and a nitrogen gas reservoir. The necessary vacuum, the gas exchange pressure and the number of cycles can be programmed at the keypad of the controller. By simply pressing the start button, the process begins and runs completely automatically.

The container will be evacuated to the pressure adjusted, vented with the reaction gas connected to the system, and the pre-programmed number of cycles is processed automatically. When using this anaerobic gas system, no additional chemicals are required to create an anaerobic environment.

Anaerobic digestion is a process through which bacteria breaks down organic matter- examples include animal waste (manure), wastewater biosolids, and food waste. The chief industries that utilize anaerobic gas systems to create an anaerobic environment include renewable energy and agriculture.

The PetriSphere system is cost-saving and easy to use. Special click-connectors provide convenient, safe and time-saving operation.

Anaerobic environment: Few structures of organisms can survive exclusively in the deficiency of oxygen (an aerobically). For example, anaerobic organisms are found in microbes of the genus Clostridium, in parasitic protozoans from the gastrointestinal tract of humans and additional vertebrates, and in ciliates connected with sulfide-containing sediments.

Organisms capable of switching between aerobic and anaerobic existence are found in forms of fungi recognized as yeasts. The ability of an organism to function both in an aerobic and anaerobic environment amplifies the variety of sites in which it is able to exist and transmit some advantages over organisms with fewer adaptive perspectives.

The Petrisphere allows me to perform experiments under reproducible conditions that would otherwise be prohibitively expensive if run in anaerobic glove box. The machine itself is highly portable and easy to maneuver.
