In aseptic filling processes, filling accuracy has always been a key indicator. However, as biologics become increasingly complex, the industry’s focus is also quietly shifting. For sensitive substances such as protein drugs, nucleic acid drugs, and high-viscosity formulations, product contact materials are becoming an indispensable aspect of process development. The filling needle is no longer just a standard component that performs the filling action; it may also become one of the variables affecting formulation stability and process flexibility. Under this trend, single-use filling needles with a non-metallic contact path are beginning to be evaluated by more and more companies as a new direction.
Stainless steel remains a mature material for product contact applications, but it is not the only answer in all scenarios.
For certain sensitive formulations, the selection of filling needles should not only consider mechanical performance and cost, but should also comprehensively take into account requirements such as contact materials.
From the above comparison, it can be seen that differences in materials ultimately translate into differences in process risks. For conventional formulations, stainless steel remains the first choice due to its excellent mechanical properties; however, when we focus on high-value biologics with complex formulations and high environmental sensitivity, the metallic interfacial properties of traditional stainless steel may pose additional process challenges.
Potential impacts that stainless steel needles may bring in specific scenarios:
1. Metal ion-related oxidation risks
In certain formulation systems that are sensitive to metal ions, metal contact interfaces and trace ion leaching may increase oxidation risks. Therefore, during the process development stage, some companies will evaluate non-metallic flow path options.
2. Material compatibility considerations for nucleic acid-based formulations
For nucleic acid-based formulations such as mRNA and plasmid DNA, the metal ion environment may affect molecular stability, so the choice of contact materials deserves key evaluation.
3. Interfacial stress: a "breeding ground" for subvisible particles
For systems such as high-concentration proteins and aggregation-prone formulations, contact interface characteristics may affect protein stability and subvisible particle control performance.
