Sterilization Process Advisor – Tool Overview and Instructions
The Sterilization Process Advisor is a simple and interactive tool designed to help users evaluate sterilization cycles, process hold temperatures, and understand the required information for quality dossier submissions. The tool provides tailored recommendations based on selected sterilization cycles and entered temperature values. <<<<Link for using the tool >>>>>
How to Use the Tool
Select a Sterilization Cycle:
Use the dropdown menu to choose a sterilization cycle. Options include:- Ph. Eur. 5.1.1 Reference Cycle
- Overkill Cycle (F₀ ≥12 min)
- F₀ > 8 min (Non-bioburden characterized)
- F₀ > 8 min (Bioburden characterized)
- F₀ < 8 min (Post-aseptic processing)
Enter the Process Hold Temperature:
Input the sterilization process hold temperature in the provided text field (in °C). Ensure the entered value meets the minimum requirements for the selected cycle.View the Results:
Once you’ve provided both inputs:- The tool will validate the entered temperature.
- It will display whether the temperature is acceptable for the selected cycle.
- Detailed information about the process type, bioburden level, and bioburden characterization will appear.
Explore the Required Information:
The tool generates a list of required information for your quality dossier. Each item includes expandable details to help you understand the documentation requirements.
Example Use Case
- Scenario: You are using an “Overkill Cycle” with a process hold temperature of 121°C.
Steps:- Select “Overkill Cycle” from the dropdown.
- Enter “121” in the temperature field.
- The tool confirms the validity of your cycle and provides a list of documentation you need for submission.
Important Notes
- Accurate Inputs: Always ensure the entered temperature matches the actual process hold temperature for precise recommendations.
- Educational Purposes: This tool is intended for educational and advisory use; always consult with a regulatory or sterilization expert for specific requirements.

Fbiological Calculator for Moist Heat Sterilization
Calculate biological lethality (Fbio in minutes at 121°C) for overkill (heat-stable products) or product-specific (heat-sensitive) approaches. Based on SAL ≤10^-6.
For heat-stable products. Assumes worst-case bioburden (10^6 spores, D121=1 min). Targets ≥12-log reduction of BI (e.g., Geobacillus stearothermophilus, 10^6 CFU, D121 ≥1.5 min). Minimum Fbio ≥18 min. Validation: Half-cycle (6-log BI kill), full cycle doubles for 12-log.
Explanation
Formula: Fbio = DT × LR
Validation notes: Half-cycle validation demonstrates ≥6-log BI kill; doubling exposure time for the full cycle achieves ≥12-log reduction.
