Thermocouple Positioning
The thermocouple is a separate sensor used to monitor and control the temperature within the refrigerator. The
factory-supplied thermocouple in the LABS cryostorage system is positioned to monitor the temperature 30”
above the tray.
Adding an Inventory Control System
The purpose of the inventory control system is to bring order to the storage of many small samples, and to
allow direct retrieval of the particular sample you need at any time. It is important to be aware that when you
lift an ICS rack from the refrigerator it is in a warmer environment. Learn to locate your sample quickly to
avoid unnecessary warming of your stored product. Keep ICS inserts (drawers or boxes) and dividers in good
repair. Replacement inserts and dividers are available from your Taylor-Wharton distributor to keep your
system as efficient as possible.
Always wear gloves when handling ICS racks or stored product, as they are very cold – read the precautions
in the Safety section of these instructions, and in Taylor-Wharton publication TW-10 “Handle With Care”, for
more detail on handling product stored in liquid nitrogen.
When removing ICS racks to retrieve product, protect the labels, plastic, and electronic areas of the
refrigerator from liquid nitrogen that may spill from the rack inserts. These parts of the refrigerator are subject
to damage from the extreme low temperature of the refrigerant.
Do not let ice or debris collect in the bottom of the freezer. Schedule periodic clean out if racks no longer
stand upright.
