Introduktion
Cell Viability Calculator — Percent viability from live and dead cell counts. Enter Live cells, Dead cells to get an instant, accurate result.
Formel
Cell viability % = live cells / (live cells + dead cells) × 100 — the standard trypan-blue exclusion viability formula.
Trin for trin

Eksempel fra virkeligheden
Example: With Live cells = 90, Dead cells = 10, the Cell Viability Calculator gives Viability Percent: 90.
Ofte Stillede Spørgsmål
What viability percentage is considered healthy for a cell culture?
Viability above roughly 90% is generally considered good for most mammalian cell cultures; significantly lower values suggest stress, poor handling, or an aging culture.
How are live and dead cells distinguished when counting?
Commonly with a dye like trypan blue, which is excluded by intact (live) cell membranes but stains dead cells whose membranes have broken down.
What inputs does the Cell Viability Calculator need?
You'll need to provide: Live cells, Dead cells. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Cell Viability Calculator?
The Cell Viability Calculator applies the formula exactly as calculated — Cell viability % = live cells / (live cells + dead cells) × 100 — the standard trypan-blue exclusion viability formula. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Cell Viability Calculator free to use?
Yes, the Cell Viability Calculator is completely free, requires no signup, and runs instantly in your browser.
Om Cellevitalitet-beregner
The Cell Viability Calculator uses a real, verifiable formula — Cell viability % = live cells / (live cells + dead cells) × 100 — the standard trypan-blue exclusion viability formula. — so results are accurate every time, not an approximation.
