Cryogenic Vials, 2.0ml, Sterile, External Threads, Attached Screwcap with O-ring seal, RB, PG, WS

What is Cryogenic Vials, 2.0ml, Sterile, External Threads, Attached Screwcap with O-ring seal, RB, PG, WS?

Cryogenic Vials, 2.0ml, Sterile, External Threads, Attached Screwcap with O-ring seal, RB, PG, WS are precision-engineered vials designed for reliable, long-term storage of biological samples at cryogenic temperatures. Manufactured by Globe Scientific under the RingSeal™ brand and sold by AmScope, these 2.0ml vials feature external threads and an attached screw cap with an integrated o-ring seal to ensure leak-proof performance. Built for stability in extreme conditions, they maintain integrity from -196°C to 121°C, making them ideal for liquid nitrogen storage, cell banking, and molecular research applications. Each vial is sterile, certified DNase, RNase, and pyrogen-free, ensuring sample purity and minimizing contamination risks in sensitive workflows.

Key features

• Leak-Proof Design — O-ring seal provides leak protection up to 9kPa.
• Temperature Resilience — Safe for use from -196°C to 121°C.
• Sterile & Certified — DNase, RNase, and pyrogen-free for sample integrity.
• External Threads — Compatible with standard lab automation and sealing systems.
• Large Writing Area — Facilitates clear sample labeling and tracking.
• Autoclavable — Can be sterilized without structural damage.
• Round Bottom (RB) — Optimized for uniform freezing and storage in racks.

Who is Cryogenic Vials, 2.0ml, Sterile, External Threads, Attached Screwcap with O-ring seal, RB, PG, WS for?

These vials are designed for laboratory professionals in biomedical research, clinical diagnostics, and biobanking. They suit scientists handling cell lines, DNA, RNA, proteins, and tissue samples requiring secure, long-term cryopreservation. The external thread design and autoclavable construction make them ideal for labs using automated systems or requiring repeated sterilization. Their certified purity supports applications in genomics, drug discovery, and regenerative medicine.

How does Cryogenic Vials, 2.0ml, Sterile, External Threads, Attached Screwcap with O-ring seal, RB, PG, WS compare?

Compared to standard polypropylene cryo vials, these RingSeal™ vials offer superior leak resistance due to the o-ring seal, reducing contamination risk during long-term storage. Unlike vials without certification, they are guaranteed free of nucleases and pyrogens, critical for sensitive molecular assays. Their external thread design provides better compatibility with sealing mats and automation than internal-thread models. While more expensive than basic vials, their durability and reliability justify the cost for high-value sample storage.
