Calculadora de recuento celular

Recuento celular con hemocitómetro: células/mL a partir del conteo y la dilución.

Introducción

Cell Counting Calculator — Hemocytometer cell count: cells/mL from count and dilution. Enter Average count per square, Dilution factor to get an instant, accurate result.

Fórmula

Standard hemocytometer formula: cells/mL = average cell count per grid square × dilution factor × 10⁴ (the hemocytometer's fixed chamber-volume conversion constant).

Paso a paso

  1. Enter the Average count per square.
  2. Enter the Dilution factor.
  3. Click Calculate to see your result instantly.

Ejemplo del mundo real

Example: With Average count per square = 25, Dilution factor = 2, the Cell Counting Calculator gives Cells Per Ml: 500000.

Preguntas Frecuentes

Why is the result multiplied by 10⁴?
Each large square of a standard hemocytometer counting grid covers a chamber volume of 1/10,000 mL (10⁻⁴ mL), so multiplying the average count per square by 10⁴ converts it to cells per mL.
Why does the dilution factor matter?
If the cell suspension was diluted before counting (e.g. mixed with trypan blue), the raw count under the microscope must be multiplied back up by the dilution factor to reflect the original, undiluted concentration.
What inputs does the Cell Counting Calculator need?
You'll need to provide: Average count per square, Dilution factor. 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 Counting Calculator?
The Cell Counting Calculator applies the formula exactly as calculated — Standard hemocytometer formula: cells/mL = average cell count per grid square × dilution factor × 10⁴ (the hemocytometer's fixed chamber-volume conversion constant). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Cell Counting Calculator free to use?
Yes, the Cell Counting Calculator is completely free, requires no signup, and runs instantly in your browser.

Acerca de Calculadora de recuento celular

The Cell Counting Calculator uses a real, verifiable formula — Standard hemocytometer formula: cells/mL = average cell count per grid square × dilution factor × 10⁴ (the hemocytometer's fixed chamber-volume conversion constant). — so results are accurate every time, not an approximation.
