Product Overview
The Blizzard NU-99728J -86°C Ultralow Temperature Freezer provides dependable storage for sensitive biological samples, including stem cells, blood, tissue, and vaccines. With a spacious 28.1 cu. ft. (796 L) interior, this unit supports high-volume sample preservation for research-intensive environments.
Precision temperature control is achieved through a dual-compressor cascade system and vacuum-insulated panel construction, ensuring stable and uniform storage conditions. Smart monitoring via audible and visual alarms, combined with a battery backup, keeps your lab informed even during power disruptions. Optional CO₂/LN₂ backup offers added security for mission-critical applications.
Engineered for durability and ease of use, the NU-99728J combines quiet operation, ergonomic access, and robust build quality; a reliable choice for PIs and lab managers dedicated to long-term research success.
Maximise Lab Efficiency with Smart Control Freezer
NuAire's Ultralow Freezer features an advanced electronic control system strategically placed at eye level, making monitoring crucial data at a glance effortlessly accessible. This intelligent interface not only displays the internal temperature, ambient temperature, and voltage in real time but also ensures the safety of your precious samples with an integrated audible and visual alarm system. With several indicator lights, users gain insight into the freezer's condition: operational status, alarm triggers, or maintenance alerts. The intuitive navigation arrows and set key empower users to customise access via passcode, adjust temperature settings, define alarm limits, and tailor freezer preferences to their specific needs, enhancing security and operational efficiency in your laboratory environment.
Secure & Efficient Storage with Advanced Insulation
The Ultralow Freezer NU-99728J revolutionises dependable research storage with its cutting-edge insulation and refrigeration system. Featuring insulated inner doors with individual latches, it ensures temperature stability, which is vital for the integrity of sensitive samples. Vacuum Insulated Panels (VIP) combined with high-density, low-conductivity polyurethane foam enhance temperature uniformity and maximise storage capacity, making every inch count. Hydrocarbon (HC) refrigerants, an eco-friendly choice, offer efficient cooling without harming the ozone layer. The quadruple outer and single-gasket inner doors create a pressure-tight seal, drastically reducing icing and thermal intrusion. This freezer is designed to meet the rigorous research storage demands, providing peace of mind with every use.
Effortless Access with Smart Freezer Design
Blizzard Ultralow Freezers are engineered for seamless access without compromising sample security or temperature stability. The innovative Pressure Equalisation Port, equipped with a heated, spring-assisted mechanism, ensures the freezer door can be easily opened right after sample insertion, preventing icing. The outer door features a locking claw latch that maintains a tight seal to minimise frost build-up and allows for effortless opening with minimal effort. The door includes a key lock and padlock option for enhanced security, ensuring your valuable research materials are safeguarded. Inside, individual latching inner doors maintain pressure-tight seals, making organising and accessing samples straightforward without affecting the entire storage environment. This freezer combines practical usability with the stringent security measures essential for high-value research storage.
Seamless Data Management in Freezers
The NU-99728J Ultralow Temperature Freezer introduces seamless data management and connectivity for modern laboratories, featuring a USB Data Port for easy download of freezer data directly from the electronic control centre. With a standard remote alarm and RS-485 ports in the power switch panel, this freezer allows for the transmission of temperature and alarm data to independent software for comprehensive monitoring and recording. An optional Circular Chart Recorder offers an extra layer of data reliability with internal temperature monitoring and recording, ensuring your research data is accurately tracked and securely managed. This integration of advanced connectivity options ensures that Blizzard ULTs meet and exceed the data management needs of today's fast-paced scientific environments.
