Your sample will be maintained
in a stainless steel tank filled with liquid nitrogen. The average temperature in
these vessels is -320°F or -190°C. The temperature is constantly monitored
by a computer-controlled probe. As an additional precaution, a manual reading is
periodically taken. The room containing these tanks is secured by an access control
system so only authorized personnel can enter. An alarm system alerts staff if the
room’s security has been breached or if the temperature in the tank becomes abnormal.
This system also electronically notifies a 24-7 manned call center. Back-up electrical
systems keep critical equipment working in case of a power failure. In any event,
a full tank can typically hold an adequate temperature without a refill of coolant
for approximately five days.
