standing, 10-liter liquid nitrogen dewar. The researcher did not properly secure the bar on the rack which holds the samples in place when the rack is lowered into the liquid nitrogen. Because of this, the tubes were not secure and fell to the bottom of the liquid nitrogen dewar when the rack was being immersed in the liquid nitrogen.

1. Take sample and cut into smaller pieces roughly ½ inch square 2. Place sample pieces into cryo bucket filled with liquid N in a strainer 3. Once the boiling has stopped, pull the strainer from the liquid N bath and let any residual liquid drain back into the bucket 4.

Liquid nitrogen can be used in both the liquid and vapor form to store biological samples. In the liquid form, samples are submerged directly into the LN2. Advances in technology have allowed for vapor phase nitrogen freezers where samples are stored above the liquid nitrogen rather than directly in it. Table of Contents show.

Liquid nitrogen is a colorless, odorless, tasteless liquid, with a boiling point of -195.79 °C (-320 °F). Liquid nitrogen can cause rapid freezing on contact with living tissue, and can result in serious injuries if exposed to the skin or eyes. Beyond injury through contact exposure, rapid boiling of liquid results in nitrogen gas production.
