Corning Cryogenic Vial 5 mL Internal Thread Round Bottom Self Standing Case of 500 Vials

Corning Cryogenic Vials (430656) – 5 mL Internal Thread, Self-Standing, Case of 500

The Corning 430656 is a high-capacity, sterile cryogenic vial engineered for the safe storage and preservation of biological specimens down to vapor-phase liquid nitrogen temperatures. Featuring a 5 mL storage volume and an internally threaded cap layout, this vial is designed to maximize packing density in standard storage boxes and automated retrieval systems. This wholesale case of 500 vials provides the reliable material integrity required by high-density biobanks, biorepositories, and advanced genomic research facilities.

Technical Performance & Design

• Internal Thread Design: The internally threaded closure creates a flush outer profile, allowing the vials to fit seamlessly into standard 81-well or 100-well storage grids without catching or crowding.
• Silicone Lip Seal Performance: Features a precision-engineered rubber silicone washer built into the cap to guarantee a secure, leak-proof seal under extreme thermal contraction and expansion cycles.
• Medical-Grade Polypropylene: Fabricated from ultra-pure, virgin polypropylene that complies with USP Class VI standards, ensuring exceptional optical clarity and **minimal extractable interference** with sensitive cell lines.
• Skirted Self-Standing Base: Built with a **skirted, round-bottom geometry** that locks into corresponding workspace racks, permitting fast and ergonomic one-handed capping and uncapping workflows.
