A Look inside the Lab

The Next Step Science “A Look inside the Lab” series is comprised of short videos and novel reading passages designed to introduce students to commonly used laboratory equipment and the scientists who use it. The series can be used to enhance an existing lesson or as a starting point for introducing a concept. 

We would like to thank our colleagues at the Children's Hospital of Philadelphia Research Institute, who allowed us to join them in their labs to film the video series. We also thank the individual scientists who generously shared their time and expertise in the interviews.  

Liquid Nitrogen Freezer  

The liquid nitrogen freezer stores items at -210 degrees Celsius. This type of freezer is used for cryopreservation of cells and tissue. It is also used for certain vaccines that require low-temperature storage for product stability.
