Functional Impact
Absorbent Pad
Assembly
Consists of two Absorbent Pads and one re-
usable metal plate located below the
cryogenic chamber basket
Helps to minimize movement of free LN
₂
and facilitate optimum cryogenic thermal
conductivity
Absorbent pads should be changed once
a year.
Alarm 1
Temperature Warning Alarm (-155°C default)
Alarm 1 is activated when the cryogenic
chamber temperature reaches or
exceeds TWARNING to alert the operator
that LN
₂
charge is nearly spent.
Biospecimens should be transferred to
appropriate cryogenic storage within a
few minutes to avoid warming to the
critical biospecimen temperature or the
CryoPod should be recharged.
Alarm 2
Temperature Critical Alarm (-140°C default)
Alarm 2 is activated when the cryogenic
chamber temperature exceeds
TCRITICAL to alert the operator that LN
₂
charge is now
insufficient
to maintain
samples below critical biospecimen
temperature. Biospecimens should be
transferred immediately to appropriate
cryogenic storage or the CryoPod should
be recharged.
Firmware ID
Alpha-numeric code indicating firmware
identity
The Firmware ID is needed when
working on technical support issues. It is
displayed on the LCD screen in the time
field for a few seconds after Power ON.
NOTE:
This can be downloaded in the
CryoPod Carrier Data Log Software.
ID Code
Three digit alpha-numeric code to indicate
individual CryoPod Carrier identity. This can
be set by the operator.
Used to facilitate differentiating units for
data log file downloads, service visits
and other laboratory use.
LCD (Liquid
Crystal Display)
The display on the electronics module.
Used to display temperature, time, alarm
status, and ID code.
Liquid Level
Sensor
Tool that fits just outside the back right corner
of the chamber basket. Used to indicate
correct fill level of LN
₂
during the manual fill
process.
A marked indicator rod connected to a
float provides a visual confirmation that
the correct volume of LN
₂
has been
added to the CryoPod Carrier
