This DIY Anaerobic chamber is considered a fully functional piece of Bio Art, As a statement from the Maker DIY community to the large Institutions that have a tendency to withhold knowledge. It was designed and built to grow cultures of Geobacter Sulfurreducens bacteria, to do research and experimentation on my other Bio Art project: a Microbial Fuel Cell project called "BactElecTric".
It is important to state the fact that this is piece of equipment intended to be used in a Bio Safety Level 1 lab environment.
Also, it was conceived to keep a low oxygen level atmosphere inside of the chamber, it is constantly pumped with inert gas such as Nitrogen or Argon.
It is NOT(repeat...not) intended to keep organisms from going outside of the chamber, it is intended to keep a desired atmosphere inside, with positive pressure.
It is NOT air tight, the positive pressure and small leaks keeps outside air from going in.
This is a functional piece of biology lab equipment, it was welcomed inside GENSPACE, the first community Biolab, based in Brooklyn, New York.
