With the revolution of new biologic medicines, the need for a scalable, aseptic, and precise method to dispense into cryogenic vials when moving into commercialization is of vital importance. Cook Regentec developed a closed semi-automated system to address this need. Additionally, the system was designed: to provide high throughput with filling rates of up to 600 tubes per hour; for ease of use with simple exchange for sets of cryogenic storage vials; and for elimination of cross-contamination concerns with disposable transfer tubing. The semi-automated system is widely adjustable, allowing users to tune the setting specific for their media. A variety of tests have been performed to benchmark the capabilities of this semi-automated cryogenic storage vial filling system. One specific test involved the accuracy assessment of this system. This was performed using two representative fluids (normal saline and Cryostor® CS-10) to demonstrate consistent performance at difference viscosities. The test was also conducted targeting a 0.8 mL fill in a 2 mL vial and a 5 mL fill in a 5 mL vial. Testing was performed on a statistically valid sample size from a representative batch size. Filling accuracy was determined by measuring weights of vials before and after fluid dispensing. Results indicate a high level of accuracy within sample groups. The coefficient of variation was less than 1% (saline 0.8 mL CV=0.87%; Cryostor 0.8 mL CV=0.13%; saline 5.0 mL CV=0.11%; and Cryostor 5.0 mL CV=0.02%). In conclusion, we have developed a high throughput semi-automated cryogenic storage vial filling system that achieved a high level of accuracy within a closed-system across multiple vial sizes, filling volumes, and fill fluids.
