Container Closure Integrity of a Glass Prefillable Syringe in Deep Frozen Storage Conditions

The article "Container Closure Integrity of a Glass Prefillable Syringe in Deep Frozen Storage Conditions" by Jessica Baseggio and colleagues, published in December 2023, addresses the critical issue of ensuring container closure integrity (CCI) of glass prefillable syringes (PFS) in deep-frozen storage conditions, a necessity due to the development of new pharmaceutical drug modalities requiring such storage.

The study introduces a novel dye ingress test method tailored for low-temperature conditions to assess the CCI of PFS across a spectrum of temperatures down to -80°C. This method, alongside laser-based CO2 headspace gas analysis, was used to evaluate the integrity of glass PFS at temperatures between -50°C and -80°C.

The results consistently showed CCI failures below -70°C, primarily due to failures at the plunger-to-barrel interface, attributed to dimensional changes and loss of elastomer elasticity. This research underscores the importance of assessing the CCI of pharmaceutical packaging, particularly for products requiring deep-frozen storage, to ensure drug safety and efficacy.

The study also highlights the challenges and advancements in container closure integrity testing (CCIT) at sub-zero temperatures. Traditional CCIT methods face limitations due to the physical properties of materials at low temperatures, necessitating the development of alternative testing strategies.

The successful application of a modified dye ingress method and orthogonal headspace gas analysis in this study represents a significant step forward in ensuring the integrity of pharmaceutical packaging at extreme temperatures.

Furthermore, the research provides valuable insights into the behavior of materials used in container closure systems (CCS) under deep-frozen conditions, particularly the impact of temperature on the integrity of elastomer components.

This knowledge is crucial for the pharmaceutical industry as it moves towards more advanced drug formulations requiring specialized storage solutions.


Our Orifice Calculator
Precision in Fluid Dynamics Simplified

Our Orifice Calculator© stands as a cutting-edge solution, meticulously engineered to forecast gas flow rates through orifices with high precision. Incorporating essential variables such as orifice diameter, inlet and outlet pressures, gas type, molecular weight, and temperature, our Orifice Calculator© unravels the complexities of fluid dynamics. It provides precise flow rate calculations in standard cubic centimeters per minute, specifically tailored to meet the unique requirements of our users.

To enhance our customers' ability to choose the perfect orifice for their specific needs, we integrate this proprietary calculator into our extensive service offerings. With our advanced laser drilling technology, we precisely craft orifices to exacting standards.

The foundation of our calculator lies in the principle that accurate flow rate predictions for both gases and liquids can be consistently achieved through detailed flow calibration in controlled conditions. This ensures that our customers receive solutions that are not only precise but also perfectly aligned with their diverse application needs.

The Orifice Calculator© is a breakthrough in simplifying fluid dynamics calculations for laser drilling professionals. This tool is engineered to provide accurate gas flow rate predictions through orifices, considering factors like orifice diameter, inlet and outlet pressures, gas type, molecular weight, and temperature. It aims to make complex flow rate calculations straightforward and precise, tailored to the specific needs of each project.Incorporating the Orifice Calculator© into our laser drilling services enhances our ability to create orifices that perfectly match project specifications. This precision stems from the calculator's foundation in flow calibration under controlled conditions, ensuring reliable flow rate predictions for gases and liquids alike.

Our calculator transcends traditional measurement limitations by employing a 'flow diameter'-a value slightly adjusted from the actual throat diameter-enhancing the accuracy of flow calculations across different gases and flow conditions. This approach not only streamlines the computation process but also significantly mitigates the variability introduced by the physical characteristics of the orifice, ensuring reliability and precision in predicting fluid flow rates.
