The programmed cooling box does not need to add any alcohol liquid, and can provide - 1 ℃ for cells under the refrigerator condition of - 80 ℃

The cooling rate per minute meets the * * * conditions for the freezing of most cells. The cooling box is made of advanced polyethylene foam.

It contains an alloy inner core, which has no impact on the freezing environment and will not affect other frozen samples around. The effect of cell cryopreservation was the same

And the experimental repeatability is good.

characteristic

Easy to use

Alcohol liquids are not required for freezing

Lower subsequent use cost

Better cell viability

The experiment has good repeatability

usage method:

1. Put the cryopreservation tube containing cells into the program cooling box stored at room temperature and cover the cooling box cover.

2. Put the program cooling box into the - 80 ℃ refrigerator and freeze it for more than 4 hours to achieve the freezing effect.

3. Take out the procedure cooling box and quickly move the cryopreservation tube to liquid nitrogen environment for storage or other subsequent operations.

4. Place the program cooling box at room temperature after use, and standby after the program cooling box and alloy inner core are restored to room temperature.

matters needing attention

1. Before putting it into the refrigerator, please ensure that the metal ring lies flat at the bottom of the box and the cover is covered.

2. After putting into the refrigerator, avoid being close to other substances, and ensure that there is a gap of 2.5cm around.

3. When idle, please put it in a dry and cool place and try to avoid high temperature above 60 ℃ and ultraviolet light.

4. It is strongly recommended to check the cell activity after cryopreservation, and then terminate the culture of primitive cell line
