A cryo vial (1.8 mL) is a specialized type of container used for the long-term storage of biological samples, such as cells, blood, tissue, or other biomolecules, at very low temperatures, often in liquid nitrogen or ultra-low temperature freezers. The 1.8 mL size refers to its capacity, which is ideal for small sample volumes.

Key features of cryo vials include:

• Material: Typically made of medical-grade polypropylene, which can withstand freezing temperatures down to −196°C (the temperature of liquid nitrogen) without cracking.
• Screw cap: Equipped with a secure, leak-proof screw cap that may also have an O-ring seal for added protection against contamination or evaporation.
• Graduation marks: Some vials have markings for precise measurement of sample volume.
• External or internal thread: Cryo vials come in two varieties—external thread vials for greater sample volume and internal thread vials for a more secure seal.
• Sterility: Cryo vials are often pre-sterilized to prevent contamination during sample collection and storage.
• Labeling: Many cryo vials have areas for writing sample information or are compatible with barcoding for tracking purposes.

These vials are widely used in research labs, clinical settings, and biobanks for the storage of cell cultures, DNA/RNA samples, proteins, and other biological materials that need to be preserved for future analysis or experiments.
