Maxell Seiki recently launched the “Intelligent Microtube,” which is aimed at the medical device and drug-development markets. Designed with an embedded RFID chip, the microtubes are used to cryopreserve expensive cells, protein and DNA. Because the RFID chip is embedded into the bottom of the microtube, fatigue failure seldom occurs because the coil-on-chip RFID component is tolerant of heat shock and thermal stresses. This enables samples to be stored at –80°C.
The Intelligent Microtube can save the data because the coil-on-chip RFID part can rewrite the data. Also, the reader/writer for the Intelligent Microtube can read and write even if frost attaches to the microtubes because the RFID chip is integrated into the bottom of the microtube. Moreover, the reader/writer can simultaneously localise microtubes in a rack without handling and read or write to 48 microtubes using a single operation.
