Two-Stage Plunger System
See Us at Booth #363
Sodick Plustech will showcase its V-Line two-stage plunger system at NPE. The company use the unique system to mold a medical syringe made of TOPAS® cyclic olefin copolymer (COC) from TOPAS Advanced Polymers in a mold developed by Nypro Inc.
The prototype application demonstrates the use of COCs as a viable replacement for glass in syringe applications. TOPAS cyclic olefin copolymer is crystal clear with outstanding moisture barrier and dimensional consistency. For pharmaceuticals, TOPAS COC permits long-term drug storage and design flexibility, plus avoids the delamination problems associated with glass.
Unlike other engineering thermoplastics or glass, TOPAS polymer offers a non-ionic, minimally reactive surface, the company states. This non-polar substrate does not promote adsorption, denaturation, aggregation, or precipitation. With lower leachables and extractables, TOPAS resin preserves long-term drug purity ensuring better quality at high yields and potentially lower part cost.
