Regardless of temperatures source
在ice
- Adapts from ambient (25˚C) to <4˚C in 60-90 seconds*
- 样品和标签保持干燥
- Hours of ice cooling without direct ice contact
在dry ice
- Adapts from ambient (25˚C) to -78˚C in approximately 5-7 minutes*
- Eliminates ethanol from snap freezing
- Equal or better freezing rate as compared to direct immersion into dry ice or alcohol slurry
In liquid nitrogen
- 从环境(25°C)适应大约12-14分钟的大约-150°C*
- 蒸气屏障可防止环境空气
- No direct contact between samples and LN2
Heat sources
- Use with water baths, hot plates, incubators and other heat sources to keep samples warm
