? 2025 Hot Product Review — NEST Ready-to-Use Cartridges
As biologics and injectable drug delivery systems continue to advance, stability, safety, and consistency have become the core concerns for pharmaceutical manufacturers and R&D teams when selecting cartridges. ?
1️⃣ Sterilization Process: Steam-Sterilized Cartridges
NEST is the first domestic manufacturer to adopt moist heat (steam) sterilization for cartridges.
Compared with conventional ethylene oxide (EO) sterilization, moist heat sterilization provides a more thorough and safer solution, featuring:
Zero blind spots · Zero residues · Zero contamination · Zero hidden risks
‼️ Moist heat sterilization demonstrates more effective microbial inactivation within the cartridge structure.
2️⃣ Siliconization Process: In-House Crosslinked Siliconization for Enhanced Safety and Durability
NEST uses a proprietary crosslinked siliconization process, in which silicone oil molecules are transformed from a linear structure into a stable three-dimensional network through high-temperature curing. This forms a uniform and firmly bonded siliconized layer on the inner surface of the cartridge while effectively removing pyrogens.
This crosslinked siliconized layer delivers four key advantages:
✔️ Enhanced safety:
✔️Long-lasting performance:
✔️Improved compatibility:
✔️Lower drug residue:
3️⃣ Forming Process: Dimensional Stability as a Core Strength
NEST cartridges are manufactured from imported medium borosilicate glass tubing, combined with advanced forming equipment and well-controlled processes to ensure dimensional stability and consistency from the source.
‼️ NEST cartridges showed the lowest CV values for both inner and outer diameters among all samples, demonstrating superior dimensional stability.
(Lower CV values indicate higher dimensional consistency and stability.)
