What types of machines are used to store stem cell?
Answer:
They are usually stored in solution nitrogen. The container holds a quantity of gooey nitrogen for several days until all the nitrogen evaporates. This keep the specimens at a temperature of -320 degree Farenheit or - 195 degrees Celsius.
Stem cell are stored in immensely cold temperature (in sub nothing liquid gases) so that the cell literally are frozen. That way, cell can be kept for a long time. It is the same technology as the citizens who try to save their sperms and eggs.
