Septum Vial Cap Integrity: Impact on Analytical Data Quality and Reliability

characteristics. The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that

Dec 11, 2018 · The vials should be completely filled at the time of sampling, so that when the septum cap is fitted and sealed and the vial is inverted, no headspace is visible. The sample should be hermetically sealed in the vial at the time of sampling, and not opened prior to analysis to preserve its integrity.

Septa Quality The 1.5 and 4mL vials use a PTFE/silicone septum and its cleanliness is suitable for everyday applications as well as the most discriminating LCMS analyses. The septum is press-fit inside the cap without any bonding agents, which could potentially contaminate samples. It also prevents the needle from pushing the septum into the vial.

To limit the impact of siloxane bleed, a phenomenon that can compromise analytical sensitivity and reduce lab productivity, Aijiren has developed an industry-leading conditioning process. Siloxane leeches from the silicone layer of the septum and, in untreated septa, levels increase due to multiple injections, elevated temperatures or solvent

Innovative screw cap & vial design ensures proper screw cap seal every time, independent of operator, so there’s no more failures from: Cap tilt; Cap deformities; Dislodged septa; Push-through septa; Now you can reduce re-analysis costs and increase data integrity and sample throughput. No-Fail SureStop Vials & AVCS Caps ›

Data interpretation: The inherent package integrity results for all test packages must conform to the maximum allowable leakage limit demanded of the product to ensure that there is no risk to product microbiological quality, and no, or inconsequential, impact on product physicochemical quality attributes. 5.

Figure 1 illustrates a complete sample containment solution of the vial, cap, and septum, and their relationship to each other. A needle is shown piercing the cap septum and, as shown in the fi gure, the septum should be the only component that comes into contact with the needle. Autosampler needle Septum Cap Vial Sample location F igure 1.

Made of autoclavable borosilicate glass and available with a wide assortment of special closures and accessories, these vials are ideal for sample collection and small derivatization reactions

The vial sealing process is a critical process step during fill-and-finish operations, as it defines the seal quality of the final product. An adequate force to remove the f The majority of parenteral drug products are manufactured in a glass vials with an elastomeric rubber stopper and a crimp cap.

Data reliability definition. Data reliability means that data is complete and accurate, and it is a crucial foundation for building data trust across the organization. Ensuring data reliability is one of the main objectives of data integrity initiatives, which are also used to maintain data security, data quality, and regulatory compliance.
