1. What is G Force in Centrifuge?

G force (gravitational force) in a centrifuge represents the relative centrifugal force experienced by samples. It indicates how many times greater the acceleration is compared to Earth's gravity (9.81 m/s²).

2. How Does the Calculator Work?

The calculator uses the g force formula:

Where:

• \( g \) — G force (relative to Earth's gravity)
• \( v \) — Velocity (m/s)
• \( r \) — Radius (m)
• \( 9.81 \) — Earth's gravitational acceleration (m/s²)

Explanation: The formula calculates the centrifugal acceleration relative to standard gravity, providing the g-force value used in centrifuge applications.

3. Importance of G Force Calculation

Details: Accurate g force calculation is crucial for determining appropriate centrifugation parameters in laboratory settings, ensuring proper sample separation without damaging materials.

4. Using the Calculator

Tips: Enter velocity in meters per second (m/s) and radius in meters (m). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical g force range for centrifuges?
A: Laboratory centrifuges typically range from 100g to 20,000g, while ultracentrifuges can reach over 100,000g.

Q2: How does radius affect g force?
A: Larger radius at the same rotational speed produces higher g force, as the formula shows g force is inversely proportional to radius.

Q3: Can I use RPM instead of velocity?
A: Yes, but you'll need to convert RPM to linear velocity using the formula: v = (2πr × RPM) / 60

Q4: Why is 9.81 used in the formula?
A: 9.81 m/s² is the standard acceleration due to gravity on Earth, used to express centrifugal force relative to Earth's gravity.

Q5: What are common applications of centrifuge g force calculations?
A: Blood sample separation, DNA extraction, protein purification, and various laboratory procedures requiring particle separation by density.
