CRYO VIALS External Thread

The generated image shows laboratory cryo vials with external screw threads, designed for secure closure. The vials are made of transparent plastic, allowing clear visibility of the contents inside. Each vial is topped with a blue screw cap that threads externally onto the vial body, providing a tight and reliable seal suitable for ultra-low temperature storage. These small-sized vials are commonly used for cryogenic storage of biological samples, ensuring sample integrity and preventing contamination. The design is clean and functional, optimized for laboratory use in cryopreservation.
