Safety Information
Your Thermolyne LOCATOR and LOCATOR Plus Series
have been designed with function, reliability and safety in
mind. For safe operation, please pay attention to the alert
signals throughout the manual.
Please Read
All cryopreservation vessels, regardless of who manufac-
tures them, use a vacuum to provide the super insulative
properties needed to keep nitrogen in a liquid form. They
are very similar, in fact, to the thermos vessels you may
have used to store coffee, soup or milk. Remember how
fragile they were? Since no vacuum is perfect or will last
forever, we suggest that you monitor the consumption of
liquid nitrogen used by your vessel on a regular basis, i.e.
every 1-2 days. By monitoring, you may be able to antici-
pate subtle changes in consumption and possibly react to
problems before they arise. You may opt to use a level
monitor for this purpose. (See page 7 for level monitor
operation.).
Also, if your samples are super critical, one-of-a-kind, or
irreplaceable, consider allocating your samples to 2 sepa-
rate vessels. Remember the old adage about placing all
your eggs into one basket....
Finally, because no vacuum will last forever, consider
having your vessel tested by a qualified cryovessel manu-
facturer every 7-10 years, regardless of any problems (or
lack thereof) you may have had in the past. This will help
insure your samples against sudden loss of nitrogen due
to vacuum failure.
Warnings
1.
Liquid Nitrogen is extremely cold; it boils at -

2.
To avoid injury due to frostbite or ruptured vials
use extreme care whenever handling liquid
nitrogen, liquid nitrogen storage or transfer ves-
sels, or any objects which have come in contact
with liquid nitrogen.
