3、 Product Function and Usage
1. Suitable for rapid and repetitive freezing of biological samples in molecular biology, such as alcohol precipitation of DNA/RNA, it is your best choice for protecting, transporting, and storing sensitive samples and safely terminating reactions.
2. Used for ice bath, transfer, and storage of deep frozen samples, it can be used to prevent enzyme inactivation, PCR sample preparation, sample transfer, and slow thawing of frozen samples.
3. No need to melt in an ice bath to reduce the risk of pollution.
4. The ice box can effectively cool the sample and maintain the temperature at 4 ℃, -21 ℃, -55 ℃ and other temperature states for a long period of time for up to 3 hours.
5. Each product is equipped with a temperature sensitive color change function. When the temperature exceeds 7 ℃, the color of the ice box bottle cap changes from blue to white. Different colors can be displayed according to the temperature change, allowing you to more intuitively "see" the ice box temperature, ensuring safe operation, saving space, and pollution-free.
6. The specially designed hole pattern can prevent sample freezing.
7. Each product comes standard with a transparent protective cover, effectively extending the temperature control time and providing more protection for your experiment.
