Thermo Scientific Cryotubes 1.8 ml Total of 9 Racks of 48 Freezer Tubes

Thermo Scientific Nunc™ 374501 1.8 ml CryoTube™ (Internal Thread, Sterile)

The Thermo Scientific Nunc 374501 is a premium 1.8 ml cryogenic storage vial engineered for the long-term preservation of cells, biological samples, and genomic material. Manufactured from high-purity, medical-grade polypropylene, these vials are designed to withstand extreme thermal stress, ranging from standard laboratory freezing to the vapor phase of liquid nitrogen (-196°C). The 374501 features an internal thread design with a co-molded silicone gasket, providing a superior leakproof seal that minimizes the risk of contamination during storage or transport. With a star-foot bottom for one-handed operation in compatible racks and a large white writing area for sample identification, these CryoTubes are the industry standard for biobanks and high-density storage applications.

Technical Performance and Design

• Internal Thread with Silicone Gasket: The internal threading combined with a high-performance silicone gasket ensures a high-integrity seal, preventing the ingress of liquid nitrogen and protecting samples from environmental contamination.

• Cryogenic Reliability: Validated for use in the vapor phase of liquid nitrogen (LN2) and compatible with temperatures as low as -196°C, ensuring structural integrity during long-term cryogenic storage.

• Star-Foot Base: The specialized star-foot design allows the vial to lock into Nunc™ CryoTube™ racks, enabling convenient one-handed opening and closing for increased lab efficiency.

• High-Contrast Identification: Features a large, white thermally-bonded writing area and clear 0.1 ml graduations, allowing for easy labeling and rapid volume verification at the bench.
