Table of Contents

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 -
196°C.
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.
3. Leave no areas of skin exposed.

Alert Signals

4. Always wear proper safety attire over clothing:
face shield, cryogenic gloves, cryogenic apron.
5. Do not tightly seal liquid nitrogen containers or
prevent nitrogen gas from escaping.
6. Always handle ampules with tongs. They may
explode when removed from the vessel.
7. Use extreme care to prevent spilling and splash-
ing liquid nitrogen during transfer and removal of
storage contents and holders.
8. mmediately remove any clothing or safety attire
on which liquid nitrogen has been spilled or
splashed.
9. Get immediate medical attention for any frostbite
injuries due to liquid nitrogen.
10. Never overfill liquid nitrogen vessels. Liquid
nitrogen level should never be above the tops of
the racks inside the vessel. The excess weight
will crack the neck and result in vacuum failure.
11. When inserting or removing racks be careful not
to come in contact with the neck tube area of
the vessel. Remove or insert racks slowly in a
vertical manner. Scratches on the neck tube
area can cause premature vacuum failure.
12. Do not tamper with or remove vacuum port (cov-
ered by a black plastic cap on side of vessel);
this will void warranty.
13. Do not spill liquid nitrogen on vacuum port - this
can cause vacuum failure.
14. Always keep liquid nitrogen vessel in an upright
position.
15. Do not use this Locator vessel for transport.

General Specifications

Before using your new LOCATOR or LOCATOR Plus ves-
sel, carefully inspect the vessel prior to use. Check for
signs of damage which may have occurred in shipment. t
is advisable to fill (See Filling nstructions) all new units
with liquid nitrogen and watch liquid nitrogen loss rate for
a few days. f there are any problems, call Customer
Service as soon as possible.
The Warranty Registration card enclosed with the vessel
must be completed and returned to the factory within 30
days to make warranty effective. This information must
include the serial number, which is located on the label on
the vessel.
6
Unpacking
Note
The most prevalent cause of failure of
liquid nitrogen storage vessels is
mechanical. The vessel neck tube
supports the full weight of the inner
shell and all the liquid nitrogen it con-
tains. A side blow to the vessel causes
the inner shell to swing in a pendulum-
like motion causing the neck tube to
be damaged. Any storage vessel
which has been in an accident, has
been dropped or lowered to hit on its
side will tend to fail more rapidly than
one which has not.
Note
f you must transport samples under
cryogenic conditions, consider the
Arctic Express line of Dry Shippers
found in the Thermolyne catalog.
Caution
Exercise caution when moving your
LOCATOR or LOCATOR PLUS vessel.
LOCATOR and LOCATOR Plus cryobi-
ological storage systems are not trans-
portation vessels. Transport carts are
designed for mobility within the lab or
lab to lab only. Moving full vessels
long distances, over cracks in floor,
thresholds, on inclined ramps or in ele-
vators can cause premature vacuum
failure.

Filling nstructions
To avoid damage to your LOCATOR or LOCATOR Plus
cryogenic storage vessel which may result in premature
vacuum loss, it is important that the following procedure
be used when adding liquid nitrogen to a warm vessel:
1. Add only a small amount of liquid nitrogen (5-10
liters) to a new or warm vessel.
2. Allow this small amount of liquid nitrogen to sit
in the covered vessel for a minimum of 2 hours.
This will limit stress caused by the sudden tem-
perature change associated with adding liquid
nitrogen to a warm vessel.
3. Add an additional 15 liters of liquid nitrogen to
the vessel.
4. Allow vessel to sit for 48 hours and monitor liq-
uid nitrogen consumption with a wooden yard-
stick or Level Monitor.
5. Fill LOCATOR or LOCATOR Plus as indicated.
(See Caution on this page.) Remember to allow
for displacement of liquid nitrogen when racks
and boxes are inserted.
6. nsert and remove racks slowly. Allow liquid
nitrogen to run out of boxes and off of racks.
Measuring Liquid Nitrogen
Quantity
1. Use a wooden yardstick to measure liquid nitro-
gen level. Never use a hollow tube or plastic
dipstick to measure the liquid nitrogen level.
2. Level will be indicated by frost line which devel-
ops when dipstick is removed.
3. Level Monitor can be used for constant meas-
urements.
7
Operation
Caution
• Never overfill your LOCA-
TOR or LOCATOR Plus ves-
sel with liquid nitrogen. The
liquid nitrogen level in your
tank (with racks inserted)
should never be above 20
inches (50 cm) for LOCATOR
4 and LOCATOR 8, 10 inch-
es (25 cm) for LOCATOR Jr.,
22 inches (55.8 cm) for
LOCATOR 4, 6 and 8 Plus
and 12 inches for LOCATOR
Jr. Plus. Filling the tank up to
or above the bottom of the
neck tube may cause imme-
diate or premature vacuum
failure to occur.
• When inserting or removing
racks, be careful not to come
in contact with the neck tube
area of the vessel. Remove
or insert racks slowly in a
vertical manner. Scratches
on the neck tube area can
cause premature vacuum
failure.
• Do not spill liquid nitrogen on
vacuum port (covered by a
black plastic cap on side of
vessel) - this can cause vac-
uum failure.

Storing Samples in Vapor
Phase
1. Remove the 2 bottom-most cryoboxes from
each rack.
2. Measure the height of 2 cryoboxes stacked on
top of each other.
3. Fill vessel with liquid nitrogen to the height
obtained from step 2 using a yardstick to meas-
ure liquid level in vessel.
4. Place racks into vessel without the 2 bottom-
most cryoboxes.
— Samples are now above the liquid nitrogen and are
stored in the vapor phase.—
mportant—A level monitor should always be used when
you store your samples in the vapor phase because of
the already low levels of liquid nitrogen. Please refer to
page 12 for the correct level monitor for your system.

Principles of Operation
The innovative L QU D N TROGEN LEVEL MON TOR
from THERMOLYNE utilizes ultrasonic sound waves to
sense the level of liquid nitrogen inside a or LOCATOR
Plus cryogenic storage vessel. A microprocessor control
provides continuous indication of the liquid nitrogen level
inside the LOCATOR or LOCATOR Plus. Audible and
visual alarms also provide an early warning of low level
conditions.
ULTRASON C sound waves sense the level of liquid
nitrogen inside the LOCATOR or LOCATOR Plus vessel.
By using ultrasonic sound waves to sense the level of liq-
uid nitrogen, no physical probe is required to sense the
level of liquid nitrogen. Conventional devices use probes
which must be in physical contact with the liquid. This
physical contact increases liquid nitrogen consumption.
There is NO increase in liquid nitrogen consumption by
using the THERMOLYNE LEVEL MON TOR.
Microprocessor Functions
5 segment LED indication of the liquid nitrogen level.
The LED display is graduated in 5 segments; Full, 3/4,
1/2, 1/4 and Empty, similar to a fuel gauge on an automo-
bile. The bright orange LED display provides quick and
reliable visual indication of the level of liquid nitrogen
inside the LOCATOR or LOCATOR Plus vessel.
Audible and Visual alarms
1. “LOW LEVEL” indicator light flashes on and off
when 2” of liquid nitrogen remains inside the
LOCATOR or LOCATOR Plus vessel. n this sit-
uation, the level of liquid nitrogen is low, and
you are alerted to re-fill the vessel as soon as
possible.
2. An AUD BLE alarm will sound intermittently
when 1” of liquid nitrogen remains inside the
LOCATOR or LOCATOR Plus vessel. The “LOW
LEVEL” light described above will continue to
flash as well. n this situation, the liquid nitrogen
15
ACCESSORY LIQUID NITROGEN LEVEL MONITOR OERATION

is dangerously low, and you are alerted to re-fill
the vessel immediately.
3. The 5 segment LED display becomes lit and an
audible alarm sounds continuously when the
LOCATOR or LOCATOR Plus vessel has no
more liquid nitrogen or if the level inside the
vessel is falling at a rate of 1/2” per hour or
more. n this situation, you are alerted that an
emergency exists. Either there is no more liquid
nitrogen inside the LOCATOR or LOCATOR
Plus vessel, or the level of liquid nitrogen is
dropping rapidly, due to a vacuum failure of the
LOCATOR or LOCATOR Plus vessel.
Safety Feature
A “RESET” switch lights and an audible alarm sounds
intermittently if the user does not reset the monitor after
removing vessel cover. The microprocessor must be reset
each time the cover is removed from the LOCATOR or
LOCATOR Plus.
Before removing the cover, the reset button must be
pushed, illuminating the reset light. While in this
reset/hold mode, the monitor is not sensing. After five
minutes in the reset/hold mode, an audible alarm will
sound, alerting you to deactivate the reset/hold mode and
replace the cover on the vessel.
Operation of Level Monitor
Once the cover with the monitor has been placed on the
vessel and plugged in, it will take the system about 15
minutes to equilibrate before an accurate measurement of
the liquid nitrogen will be indicated. This equilibration
process will occur each time the vessel is used. Each
time a vessel is opened, the stabilized chamber tempera-
ture is disrupted. The system requires a stable tempera-
ture to determine an accurate liquid nitrogen level.
f you have just purchased a new LOCATOR or LOCA-
TOR Plus along with your monitor, allow at least 1 day for
the liquid nitrogen to equilibrate the vessel before plug-
ging in the unit. This will avoid false alarms.
