(In the event the reagent is additional over the sample floor, you might introduce oxygen in the sample.) Squeeze the pipette slowly and gradually so no bubbles are introduced by way of the pipette.

Pros: VCS testing is reasonably priced, quick, and straightforward. It will also be very easily recurring all through remedy. A person review observed that VCS scores were lower amongst employees of a faculty that were subjected to water harm than personnel at an unaffected school [8].

(b) addition of the seed straight to the sample BOD bottles. Process (a) needs a calculation to find out the quantity of seed for every dilution because the level of seed will fluctuate with the amount dilution water utilized for each sample dilution.
