Breaking Down the Features of VWR Chlorobutyl Serum and Lyophilization Stoppers, West Pharmaceutical Services 44002117 Serum Stoppers
Specifications
The VWR Chlorobutyl Serum and Lyophilization Stoppers, West Pharmaceutical Services 44002117 Serum Stoppers are molded from elastomeric formula 4432/50 Gray, known for its low levels of organic and metallic extractables. They are specifically designed without plasticizers, 2-Mercaptobenzothiazole, nitrosamine precursors, or natural rubber latex to minimize potential contamination. They are of a standard type, with a 20mm size, and correspond to West No.: 44002117.
These specifications are critical because they directly impact the purity and stability of the stored product. The low extractable levels ensure minimal interaction between the stopper and the contents of the vial, while the absence of allergenic materials makes them suitable for a wider range of applications.
Performance & Functionality
The VWR Chlorobutyl Serum and Lyophilization Stoppers, West Pharmaceutical Services 44002117 Serum Stoppers excel in their primary function: maintaining a sterile and airtight seal. The FluoroTec fluorocarbon film treatment on the top and bottom surfaces acts as an excellent barrier against organic and inorganic extractables, minimizing interactions between the closure and the stored product. The low surface energy of the film also reduces protein adsorption and provides lubricity without the need for silicone oil.
The strength lies in the consistent and reliable seal that minimizes contamination risks. A minor weakness could be the initial cost, but the long-term benefits outweigh this concern. Overall, these stoppers meet and exceed expectations for performance and reliability.
Design & Ergonomics
The stoppers exhibit excellent build quality, with a uniform density and precise molding. The gray elastomeric material provides a secure grip and is comfortable to handle. The enhanced lyophilization stoppers are coated with a cross-linkable polydimethylsiloxane on the underside of the flange, reducing friction during filling line processes.
The design is inherently user-friendly. There is minimal learning curve involved in their application.
Durability & Maintenance
The VWR Chlorobutyl Serum and Lyophilization Stoppers, West Pharmaceutical Services 44002117 Serum Stoppers are designed for long-term durability. They can withstand repeated sterilization cycles without significant degradation. They are also easy to clean and maintain.
