In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.

Excipients are often overlooked, yet they significantly impact the overall quality and performance of the medication. For example, in liquid formulations, excipients can help ensure that the active ingredient is evenly distributed throughout the solution, maintaining uniformity in dosages. Additionally, excipients can improve the shelf life of a product by providing stability and protecting active ingredients from degradation due to moisture, heat, or light.

Moreover, real-time stability studies are conducted under recommended storage conditions. These long-term studies are essential as they help to validate the findings from accelerated studies, providing a comprehensive understanding of how the API will function during its intended shelf life. The data obtained from these stability tests inform pharmaceutical manufacturers about necessary measures for handling, packaging, and labeling, ensuring that the needs of regulatory agencies, such as the FDA or EMA, are met.
