1. What is the Tocris Dilution Calculator?

The Tocris Dilution Calculator calculates dilution for concentrations (molar or mg/mL) using the standard dilution formula. It helps researchers and laboratory professionals prepare solutions with precise concentrations for experiments and analyses.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C1 \) — Initial concentration (M or mg/mL)
• \( V1 \) — Initial volume (mL)
• \( V2 \) — Final volume (mL)
• \( C2 \) — Final concentration (M or mg/mL)

Explanation: The formula calculates the final concentration after diluting a known volume of stock solution to a larger volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential for preparing solutions with precise concentrations, ensuring experimental reproducibility, and maintaining consistency in laboratory procedures.

4. Using the Calculator

Tips: Enter initial concentration in M or mg/mL, initial volume in mL, and final volume in mL. All values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for concentration?
A: You can use either molarity (M) or mass concentration (mg/mL), but be consistent throughout your calculation.

Q2: Can I use different volume units?
A: The calculator uses mL for volume inputs. Convert other units to mL before calculation for accurate results.

Q3: What if my final concentration is too low?
A: You may need to start with a higher concentration stock solution or use a smaller final volume to achieve your desired concentration.

Q4: How precise are the calculations?
A: The calculator provides results with 4 decimal places for precision, but actual experimental precision depends on your measurement techniques.

Q5: Can this calculator handle serial dilutions?
A: This calculator handles single-step dilutions. For serial dilutions, you would need to perform multiple calculations sequentially.
