We developed  new respirometer intended for monitoring respiration of
algae, fungi, insects, animals, bacterial response to antibiotics,
respiration of soil contaminated by heavy metals, bioleaching in
hydrometallurgy etc.  Up to 80 sample chambers can be connected to
Micro-Oxymax Respirometer which is equipped with O2 and CO2 analyzers
having 0.001% resolution.    Multiple experiments of different lengths can
be conducted at the same time using liquid or solid samples.  Due to the
exceptionally high sensitivity of 0.2 uL of gas/hour,  O2/CO2 Respirometer
can monitor very slow biodegradation processes in  contaminated water and
