BOD Sensor Set - VELP

The micro-organisms already present or purposely seeded in a water sample containing biodegradable organic matter, use oxygen for their biochemical processes and produce an equivalent volume of carbon dioxide. If the process develops in a closed system and the carbon dioxide is absorbed by a strong alkali, a progressive decrease of internal pressure can be measured. The standard incubation time at 20C for a reliable measurement of BOD is now universally considered 5 days and the related value is then called BOD5. This corresponds with good reproducibility, considering all the aspects of the technique itself, to 70% of the so called BOD last, that is the value at the complete oxidation, that occurs after a period of 21-28 days.

Single test set

• This simple configuration is intended for meeting the requirements of those labs where just single measures are required.
• The BOD Sensor Set is composed by a BOD Sensor, a bottle and magnetic bar.
• The use with the magnetic stirrer type MST (code 10.0160) is suggested.
