O2/CO2 Respirometer measures respiration of bacteria or algae

New respirometer is intended  to measure respiration of alga,fungi, 
bacterial response to antybiotics and toxins, respiration of soil  etc. 
Up to 80 sample chambers ( variety of sizes)  can be connected to 
  Respirometer which is equipped with O2 and CO2, analyzers 
.Optional CH4 and H2S, H2 are also avilable.  Sample 
chambers can be refreshed from the compress gas bottles or 
from the programmable gas blender. 
Respirometer is capable to measure head space gas 
exchanges on 24h basis. Multiple experiments of different 
length can be conducted in the same time using liquid or 
solid samples.
Due to the exceptionally high sensitivity 0.2 uL of gas /h, 
 Respirometer can monitor very small changes in the bacterial culture
It can also be used for testing biodegradation of plastics, hydrocarbons, 
explosives, creozote as well as respiration of insects, aquatic plants and
