Cell Doubling Time Calculator (DT) – Calculate Culture Growth Rates

Quickly determine the growth rate of your cell culture. This tool calculates the Doubling Time (DT) based on cell counts taken at two different time points.
Just enter your initial cell count (N1) and the time it was taken (T1), followed by your final count (N2) and time (T2). The calculator uses the logarithmic growth formula to provide the precise doubling time in hours.
If you have any questions or confusions about the topic, ask Sophie AI!

Cell Seeding & Mix Calculator – Hemocytometer Counting to Seeding

This all-in-one calculator takes your raw hemocytometer counts and generates a complete "Master Mix" recipe for seeding multi-well plates.

Select your plate type (e.g., 48-well).
Enter the raw counts from your hemocytometer squares (1–4) and your dilution factor.
Enter your desired target cells per well.
Result: You get a specific recipe telling you exactly how much cell stock and media to combine, and the precise volume to dispense per well.

IC50 & EC50 Calculator – Dose-Response & Inhibition Analysis

This tool performs linear interpolation to find the exact concentration required for 50% inhibition (IC50) or 50% effect (EC50). It automatically detects whether your compound is an inhibitor or an agonist.

Enter your desired concentration unit, average Blank signal (background) and average Negative Control signal (Concentration 0 : 100% viability).
Select how many concentration points you tested (2–12).
Input the concentration and average signal for each point.
Result: The tool calculates the exact IC50/EC50 value and reports if the potency is outside your tested range.

Solution Conversions Calculator: Molarity, Dilutions & Percentages

Whether you are making a molar stock from powder, preparing a percentage solution (w/v), or calculating a dilution series, this tool provides step-by-step recipes:

Select your calculation mode (e.g., Molarity, Dilution, or Dilution Factor).
Fill in the required fields (Molecular Weight, Target Volume, etc.).
Result: Receive a clear instruction, such as "Dissolve 5g in 80mL of water, then QS to 100mL," or "Mix 1 part sample with 9 parts buffer."

Standard Curve Calculator – Linear Regression & Concentration Analysis

This tool generates a linear regression line (y = mx + b) from your standards and automatically calculates the concentration of your unknown samples, including Standard Deviation adjustments.

Enter your Concentration unit an dilution factor.
Select the number of Standards and Unknown Samples you have.
Enter the concentration and average signal (Data) for your standards to generate the curve. (Notice, first concentration Conc1 is 0 as your blank)
Enter the average data and the Standard Deviation (SD) for your samples.
Result: View a real-time scatter plot of your standard curve and a bar graph of your sample concentrations.
