Estimation of time for bacteria growth.

    The "prognosis" of bacterial growth. This is important for the preparation of chemical- or electro-competent cells. The program may be used also for other organisms in the logarithmic stage of growth. It is possible to evaluate the precision of prognosis.

    The mandatory fields are indicated with (*). For evaluation it is necessary to perform two measurements in two different time points.

    The first measurement was days before at:
       h* min* => OD1 = *
    The second measurement was today at:
       h* min* => OD2 = *

    Bacterial culture will reach the indicated density

    after days at:
              =>ODf = *  

       Or, after   since the second measurement.


    Evaluation the precision of the prognosis.

    only after evaluation of the growth time

      Precision of the spectrophotometer: ±OD
      Precision of the time measurement: ±t[min]
      Precision of the evaluation: ±t[min]
    ± *
    ± *
