Optimize the Freeze Drying Cycle
We’ve combined the most sophisticated laboratory freeze dryer with the most powerful PC/PLC control system to enable One-Run Protocol development. Designed to automate and optimize the freeze drying cycle using Millrocks’ patent pending technique, the Revo™ provides all the tools you need to develop a robust protocol in as little as a single run.The Revo™ works with batch sizes from a single vial to a full load. The results are based on actual product temperatures, not batch averages, enabling the shelf temperature to compensate for the dynamic changes that occur throughout a freeze drying cycle. The result is the fastest cycle without melt-back or collapse.
Based on in-process product information, the Opti-Dry Auto control system will determine the proper freezing cycle, the proper vacuum level and shelf temperatures and then dynamically control the shelf temperature throughout the entire freeze drying cycle while maintaining a safe drying environment. The End of Primary Drying will automatically be determined using one or a combination of methods.Other protocol development systems require a large batch, use batch average data, and only work for a portion of primary drying, while the Opti-Dry Auto™ control system is active for the entire primary drying cycle. Opti-Dry Auto uses Millrocks’ patent pending ‘Critical Vial Method’ to control the shelf temperature from the warmest vial at all times, thus providing the maximum shelf temperature while eliminating the possibility of melt-back or collapse.
