Quick Answer

Cell Doubling Calculator: N=N₀·2^(t/Td) · culture planning · passages. Cell Doubling Calculator uses standard science & engineering formulas to compute accurate results instantly.

How it works

  1. 1N=N₀·2^(t/Td); generations=t/Td
  2. 2Enter seed count, doubling time and culture duration
  3. 3Reference Td: HEK293 ~24 h, HeLa 22 h, E. coli 20 min
  4. 4Passage at 80-90% confluence in log phase

The exponential model covers log phase only — lag adaptation and plateau contact inhibition are excluded, and real yields often run 20-50% below prediction. Back-calculate seed density from your log-phase window; allow ~20% extra for freeze/passage losses. Doubling time drifts with passage and conditions — measure it before critical runs.
