冷凍容器用の温度警戒装置
Document Type and Number:
Japanese Patent JP2011503618
Kind Code:
A
Abstract:
A temperature alert device to warn of imminent devitrification due to warming of a biological specimen that uses shape memory materials. The temperature induced phase transformation of shape memory materials causes a temperature responsive actuator to extend an alert rod upon warming as the specimen temperature approaches the devitrification temperature (e.g. -130° C.). The temperature alert device is automatically reset upon immersion in liquid nitrogen.
