Corning Cryogenic Vial 4 mL External Thread Round Bottom Self Standing Case of 500 Vials

Corning Cryogenic Vials (430662) – 4 mL External Thread, Self-Standing, Case of 500

The Corning 430662 is a premium, sterile cryogenic vial designed for the long-term preservation of biological samples, cells, and reagents down to vapor-phase liquid nitrogen temperatures. Featuring a 4 mL capacity and an externally threaded cap, this vial is engineered to maximize sample volume while minimizing the risk of cross-contamination. This bulk case of 500 vials is ideal for high-throughput biobanks, clinical research facilities, and cell culture laboratories requiring dependable sample security and traceability.

Technical Performance & Design

• External Thread Security: The externally threaded design ensures that the cap threads never touch the inner vial wall, reducing the risk of fluid entrapment and preventing sample cross-contamination.
• Silicone Washer Seal: Equipped with a co-molded or integrated silicone washer that provides a tight, leak-proof seal capable of maintaining structural integrity during rapid temperature shifts.
• Ultra-Pure Polypropylene: Manufactured from medical-grade, virgin polypropylene that meets USP Class VI standards, ensuring low extractables and high clarity for visual sample verification.
• Self-Standing Base: Features a skirted, self-standing bottom that locks into specialized laboratory racks, allowing for easy, one-handed capping and uncapping operations.
