Program cooling device, also known as program-controlled cooling deviceIt is a reasonable program for temperature controlled freezing of biological samples before ultra-low temperature freezing.You can choose one according to the different needs of various frozen samplesidealSuitable cooling rate for freezing. As a result, the survival rate of frozen samples is greatly improved.The technological advantages and functions of the program cooling device will directly affect the cell survival and resurrection of biological samples.

programmable controllerThe main technical advantages are:

1The temperature measurement display range should not be less than+40 ℃~-180℃.

2The temperature control range should not be less than room temperature-180℃.

3. Cooling rate: within the range of 0.5 ℃/min to 40 ℃/min, with a minimum unit of 0.1 ℃/min.

4. Heating rate: Within the range of 0.5 ℃/min to 30 ℃/min, the minimum unit can be selected as 0.1 ℃/min.

5. Temperature measurement error: should not exceed ± 1 ℃.

6. Accuracy of constant temperature control: The error should not exceed ± 0.5 ℃ in the range of 0 ℃ to -40 ℃, and the error should not exceed ± 1 ℃ in other ranges.

7The Program Cooling DeviceAccuracy of temperature rise and drop rate control:

A、When the speed is ≤ 3 ℃/min, the error should not exceed ± 0.5 ℃/min;

B、When the speed is greater than 3 ℃/min, the error should not exceed ± 5%.

8. Freezing chamber capacity: 200 × 200 × 200 millimeters. The room is equipped with four sample drawers, which can accommodate 160 freezing tubes or 8 200ml frozen blood bags at the same time.
