Tools: Bacteria Growth Calculator

The Calculator estimates the growth rate of bacteria in 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 (*).

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]
