Biological Oxygen Demand "B.O.D."
¡@
Model JPS131

PRINCIPLE

B.O.D. is the quantity of oxygen consumed by the degradation of biological material of a sample of water placed in an incubator for 5 days at a constant temperature of 20 ¢XC.


FEATURES

  • Made of chemically resistant metal the case supports 6 amber glass sample bottles of 500 ml.
  • Determination of B.O.D. is read from 4 interchangeable scales of: 0-90, 0-250, 0-600 and 0-1000 mg/l as a function of the sample, permitting a direct precise result.
  • Sample volume can be varied from 0-400 ml.
  • Comes complete with: 6 amber glass bottles, connecting tubes, 6 mercury pressure manometers, 6 places for magnetic stirrer and 6 teflon coated stir bars.
  • NOTE: To determine B.O.D. it is necessary to maintain the samples at a constant 20 ¢XC.
    This allows for the projected Kinetic curve to be determined.
  • It is recommended that a precise constant temperature incubator be used such as cooled incubator with internal power point and fan circulation.
