Dipstick for liquid nitrogen - 24" (AI tank dipstick)

Liquid nitrogen dipstick - 24"

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.  

Dipsticks are available in 2 lengths - 1m and 24".  Don't ask me why one is imperial and one is metric - it is just one of those things.

The picture is of the 1m one, but the 24" looks very similar.
