1. What is G Force Calculation For Centrifuge?

Definition: This calculator estimates the relative centrifugal force (RCF) experienced in a centrifuge based on its rotational speed and radius.

Purpose: It helps laboratory technicians and researchers determine the G force for proper sample separation in centrifuges.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — Relative centrifugal force (RCF) in g units
• \( RPM \) — Rotational speed in revolutions per minute
• \( r \) — Rotor radius in centimeters

Explanation: The G force increases with the square of the rotational speed and linearly with the radius.

3. Importance of G Force Calculation

Details: Proper G force calculation ensures effective separation of components in biological samples while preventing damage to sensitive materials.

4. Using the Calculator

Tips: Enter the centrifuge's RPM and the radius from the center of rotation to the sample. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is G force important in centrifugation?
A: G force determines the separation efficiency of particles based on their size, shape, and density differences.

Q2: How do I measure the radius (r)?
A: Measure from the center of the centrifuge rotor to the bottom of the sample tube when it's in the horizontal position.

Q3: What's a typical G force range for common applications?
A: Clinical centrifuges typically operate at 1,000-15,000 g, while ultracentrifuges can reach 100,000-1,000,000 g.

Q4: Why does RPM have a squared relationship with G force?
A: Because centrifugal force depends on angular velocity squared (ω²) in the physics equation F = mω²r.

Q5: Can I convert between G force and RPM?
A: Yes, the formula can be rearranged to solve for RPM if you know the desired G force and radius.
