This product looks like a ruler but is made of a special material so you can dip it into liquid nitrogen, take it out and read the level. It is black and turns white as it freezes in the nitrogen, so it is very easy to read the level. It is critical to maintain the liquid nitrogen level in AI tanks to retain the viability of the product stored. A major factor in the success of AI programmes is correct storage of AI straws. Sold as each.
