Frequently Asked Questions

What does this calculator calculate?

The Sterile Filtration Integrity Margin Index Calculator estimates Integrity Margin Index based on the input parameters you provide

Why is bubble point pressure important in this calculation?

bubble point pressure is inversely proportional to integrity margin index. When you enter bubble point pressure in Pa, the calculator uses it in the engineering formula to compute the output

How should I interpret the result integrity margin index?

The calculator outputs integrity margin index. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Bubble Point Pressure (Pa), Diffusive Flow Test Pressure (Pa), Critical Microbial Size (m), Fluid Viscosity (Pa·s). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
