Product feature
3 core advantages to establish new standards for long-term sample storage
- Frequent refilling or dewar replacement can be reduced, meaning highly improved LN2 operation safety
- Temperature rise caused by high-temp nitrogen during refilling can be alleviated, which guarantees the safety of stored items
- LN2 loss caused by ebullition, high-pressure impact and pipeline residual can be prevented
4 core technologies enable safer preservation of bio-samples
- Hot gas bypass design can exhaust the residual AT nitrogen in the pipeline during filling, which prevents drastic temperature fluctuation accordingly and reduces LN2 consumption
- Capacitive sensors use capacitance changes to measure the fluid level, realizing real-time display of accurate fluid level data and ensuring safe and reliable auto-filling
- With vortex baffle structure, LN2 will bump to the tank wall after filling to form vortex, which ensures stable filling and no ebullition
- Unique design of heat insulation sandwich keeps the temperature stable under -180℃ in spite of frequent or long-time stock-in and stock-out operations, ensuring the storage safety
Comprehensive software functions
- Multi-level alarm functions: high temperature alarm, high/low fluid level alarm, LN2 supply interruption alarm, lid open overtime alarm, temperature sensor failure alarm, fluid level sensor failure alarm
- Manual/automatic defogging methods give a clearer view of stored items
- Use manual start/stop key on the touch panel to control manual filling function
- Multi-level protections, such as electronic lock and mechanical lock to guarantee storage safety
- Supply tank is equipped with fluid level monitoring and fluid level alarm to guarantee LN2 supply and storage safety of stored items
- Data such as container temperature and fluid level can be viewed through data graph and data list, and data can be exported through USB port
- Information such as running status, electromagnetic valve open/close state, temperature and fluid level can be viewed in real time
- Parameters such as control parameter and alarm parameter are settable within safe setting range Parameter unit is adjustable A. Temperature switch：℃ and ℉ B. Volume switch: L and gal C. Fluid level height switch: mm and in
- Multi-level access is settable
- History alarm and history operation can be recorded, such as lid-open times
