  1. CV1, CV2 and CV3 correspond to the coefficient of variation within each vessel (vessels 1, 2 and 3). CVs correspond to the ratio between the standard deviation of each set of R1, R2 and R3, and the average of the same 3 values (as percentage).
  2. CV corresponds to the coefficient of variation between vessels.
  3. R1, R2, R3 correspond to the measurements performed to the three replicas in each vessel.
  4. St.Dev.: Standard Deviation.
