LN2 level Alarm System
Low Liquid Nitrogen Alarm System ( LN2 Alarm )
Model : DA-102
- DA-102 can be operated by DC 9V Alkaline Battery, DC-9V Adapter and the Output port for power supply. To maximaize longevity, the unit runs for ten minutes every hour (power save mode) when the battery is used. You may use DC 9V adapter, then it is automatically changed to continuous usage (normal mode).
- DA-102 displays wide ranged informatin and secure signals such as temperature, normal, refill and alarm mute. Icon bars indicate liquid nitrogen and battery levels.
- The unit holder (clip) can be easily attached and removed to / from any side of nitrogen tank using faces tape.

Cryopreservation of hESCs
The undifferentiated hESC clumps were harvested for routinepassaging as described above and then transferred to thefreezing medium (90% SR with 10% dimethylsulfoxide[DMSO]; frozen control group) with serial increments ofDMSO (0%, 2%, 4%, 6%, 8%, and 10%). Human type IVcollagen (Sigma, St. Louis) or human laminin (1, 2, and 5μg/ml; Sigma) were added to the freezing medium in eachexperimental group. Thirty to 40 clumps of hESCs wereloaded into a straw (IMV Technologies, L’Aigle Cedex,France) with slow freezing (at the rate of –1°C per minuteuntil –80°C, seeding at –7°C) using a cell freezer (CryoMagic, Miraebiotech, Seoul, Korea) and then stored in liquidnitrogen.
