Ultra-low Temperature Monitoring for Liquid Nitrogen Storage of IVF Embryos
IVF (in vitro fertilization) embryo storage is a technology of cryopreservation of embryos for a specific period of time before thawing and transplantation, which is mainly used in the field of assisted reproduction. Embryos are cryopreserved in liquid nitrogen environment at -196℃, and long-term preservation is achieved by inhibiting cell metabolism. Theoretically, it can be stored for 20 years, and the actual stable storage period is 5-10 years. The storage duration does not affect the embryo development ability, and the clinical pregnancy rate after thawing can reach 48%-63%. Therefore, it is very important to make the ultra-low temperature monitoring for liquid nitrogen storage of IVF embryos and ensure that the temperature meets the requirements. Our BlueTag TH30R-ETU Bluetooth Ultra-low temperature data logger fits perfectly.
BlueTag TH30R-ETU Bluetooth temperature monitor uses an external probe to monitor ultra-low temperature. The external probe monitors data with a high accuracy of 0.5℃ (-100℃~80℃) and ±1℃ (others) over the temperature range of -196℃ ~ 200℃. We can freely start and configure the device via the APP Tkeeper, place the external probe in the liquid nitrogen container and fix the main device outside the liquid nitrogen container. The temperature environment in the container can be remotely viewed via a Bluetooth-enabled mobile phone upon Bluetooth communication, without opening the container. Meanwhile, all data will be automatically shared with other users, facilitating teamwork and group decision making. If the temperature exceeds the preset alarm thresholds, it will be displayed in red, and will be intuitively displayed on the home page of the APP. They are all irreversible. Besides, BlueTag A100 can be optionally set for onsite audible and visual alarm. For data audit and compliance, we can add a signature on the PDF report after stopping the device.
Before leaving the factory, all devices are tested by the instruments that are calibrated by CNAS and ISO17025 accredited laboratories, and traceable to NIST according to Multi-Recognition Agreement, ensuring compliance and reliability.
