Precision Vacuum Extraction

or over 70 years, influenza vaccines have been grown in fertilized eggs, with new strains selected annually to match evolving viruses. Millions of eggs are processed every flu season to manufacture vaccines that protect people worldwide.

A critical step in this process is the harvesting of allantoic fluid, which contains the virus. This step is often automated using vacuum extraction methods, where precision is crucial:

🔹 The vacuum level must be carefully controlled to extract only the desired allantoic fluid, avoiding contamination.
🔹 Extraction machines work with multiple harvester nozzles, processing eggs in batches as trays move through the system.
🔹 As non-compliant eggs are rejected, vacuum requirements fluctuate, requiring the system to instantly adjust to variations in the batch.

Traditional vacuum systems may take several seconds to respond to changes in egg count or vacuum load. In contrast, the Equilibar Vacuum Regulator (EVR) responds in milliseconds, ensuring continuous and efficient operation.

Equilibar EVR: Instantaneous & Precise Vacuum Control

The Equilibar EVR is uniquely suited for this demanding application due to its instantaneous response and high precision vacuum regulation.

Key Benefits of Equilibar Vacuum Regulators

✅ Instant Response to Process Changes – Adjusts in milliseconds to vacuum fluctuations caused by batch variations.
✅ Precise Vacuum Control – Maintains exact setpoints to prevent over-extraction or fluid loss.
✅ Automatic Compensation for Filter Blockages – Ensures continuous operation without manual recalibration.
✅ Efficient & Reliable Performance – Keeps egg extraction systems running smoothly for high-throughput vaccine production.

Conclusion

In vaccine manufacturing, precision vacuum extraction is essential for high-yield, contamination-free harvesting. Equilibar vacuum regulators (EVR) offer ultra-fast response times and unmatched control, making them the ideal solution for automated allantoic fluid extraction.
