Cryogenic vials are used for storing several different types of samples (blood, semen, embryos, etc.) in liquid nitrogen tanks. All styles and volumes we carry are designed to snap into the 13mm aluminum canes (more commonly the 6-tab canes #347556). When ordering, the important details to consider are vial volume, base design and cap style. The most common styles are listed here, but if you have a specific type you are seeking and it isn't listed - give us a call. We can special order just about any version available. Listed here in individual units (priced each piece.).
