Cryovials are minor plastic tubes that are designed to store biological samples at very low temperatures, typically in liquid nitrogen or a deep freezer.
Cryovials are classified based on their size and the type of cap they use. The most common sizes are 1.5 ml and 2 ml, but smaller and larger sizes are also available. The caps can be either screw-on or snap-on and may be colored to indicate the type of sample inside.
Cryovials are an essential tool for any laboratory working with biological samples, providing a safe and effective way to store and transport samples over long periods of time while preserving their integrity.
