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.
